INSTRUMENTS COVERED BY MANUAL
You will find a two-part serial number on the rear panel of the instrument.
The first four digits and the letter are the serial number prefix. The last
five digits are the sequential suffix which is unique to each test set. The
contents of this manual apply directly to test sets with the same serial
number prefix as the one(s) on the title page under the heading Serial
Numbers.
If the serial prefix of your test set is not listed on the title page, your
instrument differs from those documented in this manual. The differences are
documented in the yellow manual changes supplement supplied with the manual.
To keep this manual as current and accurate as possible, Hewlett-Packard
recommends that you periodically request the latest manual changes supplement,
as it may contain replacement information as well as change information. The
supplement for this manual is keyed to the manual’s print date and part number
(on the title page) and is available on request from Hewlett-Packard.
You can order this manual in microfiche form (the part number appears on the
title page). With the manual (in 4 x 6 inch microfilm transparency format) you
will also receive the latest manual changes supplement.
DESCRIPTION AND OPERATING CHARACTERISTICS OF THE INSTRUMENT
The combination of the HP 8514B test set with the HP8510 network analyzer and
source provides a system for making S-parameter measurements over the
frequency range of 45 MHz to 20 GHz. This system is suited for making
measurements on two port devices when it is inconvenient or inexpedient to
physically reverse the DUT (device under test) to measure all four
S-parameters.
The HP8514B uses two couplers for signal separation. For measurements of
active devices, the standard HP 8514B includes:
l four RF to IF converters to measure all four S-parameters without
reconnecting the DUT, l two 90 dB programmable step attenuators for changing
(in 10 dB steps) the incident power
level at both ports, l two bias tees for applying external dc bias to both
test port center conductors.

General Information
HP 8514B/85l2A Test Sets
In the “High Forward Dynamic Range Configuration” (option 003) the Port 2
coupler is reversed to optimize dynamic range in the forward measurement
direction. Because the b2 sampler is connected to the coupler through path
instead of the coupled arm, there is less isolation between the b2 sampler and
Port 2, and the b2 power level will be higher than bl. This configuration is
better for wide dynamic range or reciprocal devices or components like
filters, cables, or antennas, where S,, is generally not measured. However, as
a result of the lower isolation between the test port and the sampler,
“sampler bounce,” appearing as an occasional spurious response related to the
VT0 frequency, can be noticeable in this “asymmetrical” test set.
The HP 8512A reflection/transmission test set uses one coupler for signal
separation. The standard HP 8512A has:
l three RF to IF converters, for making reflection (S,,) and transmission
(S,,) measurements, l no step attenuators to internally change the incident
power level, l no bias tees to apply external DC bias to the test port center
conductors.
Tables 1 and 1B list additional characteristics of the HP85148 and 8512A,
respectively. Figure l-2 shows the HP 8514B in a typical measurement set-up.

HP 8514B/85E!A Test Sets
Connect the system bus cable from the HP85148 (or 8512A) J12 8510 SYSTEM BUS
connector to the 8510 INTERCONNECTconnector of the HP85101 display/processor.
The test set IF interconnect cable and the system bus cable transmit control
signals between the test set and the network analyzer.
Signal Path Connections. The IF signals from the test set are transmitted to
the HP 85102 IF Detector by the test set IF interconnect cable (see above).
RF signals are transmitted from the source to the test set by the 3.5 mm
flexible RF cable supplied with the test set. Recommended torque is 56 N-cm
(5in.-lb) for the RF cable-to-test-set/RF input connection.
Anti-Rotation Clamps. (HP8514B only) Use these clamps to stabilize the test
port/RF cable connection. Connect the test port cables to the test ports and
tighten them as specified in the cable manual. Loosen the anti-rotation clamp
thumb screw sufficiently to slip the clamp over the cable and up to the front
panel. The clamp end with the flats should come to rest on the flats of the
test port shoulder. Finger tighten the thumb screws to prevent further
loosening or tightening of the test port/RF cable connection.
The internal O-ring is field replaceable without disassembling the anti-
rotation clamp. Pry it out with fine tweezers or a similar tool when it no
longer holds the RF cable securely. Insert the new O-ring by engaging one side
of it in the slot of the phenolic clamp donut. Use your fingers to push the
O-ring into the rest of the slot.
The HP part number of the O-ring is 0900-0007 (CD 7).
PACKAGING
If reshipping is required, each test set should be repackaged in the original
factory package. Containers and materials identical to those used by the
factory are available through Hewlett-Packard offices.
Alternatively, comparable packaging materials may be used. Wrap the test set
in heavy paper or antistatic plastic. If shipping to an HP Office or Service
Center, complete and attach a service tag (in the HP 8510 manual set). Use
sufficient shock absorbing material on all sides of the test set to provide a
thick, firm cushion and prevent movement. Seal the shipping container securely
and mark it FRAGILE.
In any correspondence with HP, refer to the test set by full model and serial
number.

Operation
HP 8514J3/8512A Test Sets
Controlling Multiple Test Sets
Option 001 for the HP 851X-series test sets allows an HP 8510 to alternately
control up to four test sets. While a measurement is proceeding on Test Set
number 1, which is equipped with option 001, test device hookup can be
accomplished on Test Set number 2, which does not need to be equipped with
option 001, unless another test set is to be connected. When the measurement
on test set number 1 is complete, then the HP 8510 can control test set number
2. Only one HP 8516A test set may be used in a multiple test set
configuration.
In a standard test set, the 20 MHz IF and control signals are applied directly
to Jll TEST SET INTERCONNECT, which connects to the HP 8510. Option 001 adds a
set of IF switches, control switches, and the JlO TEST SET INTERCONNECT
connector. This allows the selection of 20 MHz test set IF signals. As shown
in Figure 3-5, test set number 1 can apply its IF to the HP 8510 or it can
switch to pass the IF from test set number 2 through the JlO TEST SET
INTERCONNECT to the HP 8510.
INSTALLATION
Set each test set rear panel address switch to the address listed in Figure
3-5, if using a two test set configuration and Figure 3-6, if configuring more
than two test sets. Use the supplied Test Set Interconnect cable to connect
test set number 1, Jll to the HP 8510. Use the supplied Test Set Interconnect
cable to connect test set number 2, Jll to test set number 1, JlO. You may
continue this test set “daisy chain” to include up to four test sets if the
total length of all Test Set Interconnect cables does not exceed 13 meters
(about 40 feet). The last test set in the chain does not require option 001.
If the RF coaxial switch(s) is not incorporated into the system, then the RF
input to the test set must be manually switched to the active test set.
OPERATION
Initialization at Pow er-up
Upon power-up, the IF switches must be configured so that only one system test
set is active. The following procedure shows how to make one test set active.
1. Check the active lights of all system test sets.
2. Check the HP 8510’s expected test set address by pressing [LOCAL] [TEST
SET]. This should match the address of the desired test set. If not, change
the address.
3. If unselected test sets are active, (active light ON), deactivate the test
set by temporarily addressing it. Then return to the desired address.

Selecting a Test Set
Test Set IF Switching. The active test set is selected by the built-in
capability of the HP 8510 to generate an addressed command to the test set.
Each time the HP 8510 ADDRESS of TEST SET function is changed (see HP 8510
LOCAL Menu), the HP 8510 switches the previously addressed test set IF to
external and the newly addressed test set IF to internal. The test set front
panel ACTIVE indicator shows the test set status. When the test set is active
the IF signals from the test set are applied directly to Jll TEST SET
INTERCONNECT. When the test set is inactive the IF signals appearing at JlO
are passed through to Jll and on to the next test set or the HP 8510.
The address of the test set can be changed manually from the HP 8510 front
panel by selecting the ADDRESS of TEST SET function then entering the address
of the test set and pressing [xl], or it can be changed under program control
using the HP 8510 HP-IB ADDRTESS; command. The HP-IB address of a particular
test set is set by address switches on the test set rear panel.
RF Switch Driver Commands. A related feature of the HP 8510 is that when the
HP 8510 ADDRESS of TEST SET function is changed, a code sequence is
automatically issued over the HP 8510 system bus to the device at the ADDRESS
of RF SWITCH. In the recommended configuration, this device is an HP 11713A
Attenuator/Switch Driver which in turn controls one or more HP 33311C Coaxial
Switchs. As shown in Figures 3-5 and 3-6, these switches are used to select
which of the test sets receive the RF output of the network analyzer source.
The exact command issued depends upon the new value of the ADDRESS of TEST SET
function, also shown in Figures 3-5 and 3-6.
After selecting the active test set, perform the system calibration procedure
as usual. When you select a different test set, make sure that you recall the
Cal Set that applies to that test set.
Since the Cal Set Limited Instrument State does not include the number of the
active test set, a Cal Set which does not apply to the current test set can be
turned on without any HP 8510 caution messages appearing. This will cause
errors in the displayed data because incorrect error coefficients are applied
to the measured data.
It may be convenient to store a Hardware State file and an Instrument State
file for each combination of test set and cal set. You may also store your
Hardware State file on a tape or disc for future use. To change the
configuration, simply recall the appropriate Hardware State file, which sets
the Address of Test Set and issues the RF switch command, then the appropriate
Instrument State file, which recalls the Cal Set.
Operational Checks
To check operation of a multiple test set configuration, first connect a
device with a known response at test set number 1, then press HP 8510 [LOCAL]
[TEST SET], [ADDRESS of TEST SETI, enter the address of test set number 1
(this would be 20) then press [xl]. The test set number 1 measurement should
appear. Press [DISPLAY] [DATA–MEMORY] [DISPLAY: DATA and MEMORY] to store the
trace for later comparison. Now use ADDRESS of TEST SET to select test set
number 2, then switch back to test set number 1. Observe any difference in the
response between the stored trace and the result after switching back and
forth between the test sets. Repeat for each of the test sets. Any difference
in the data believed due to the option 001 IF switch or RF switching must be
investigated.
Performance Verification
Standard System Performance Verification procedures are used to verify the
operation of the option 001 test set as test set number 1. To verify the
performance of another test set in the chain, select it as the active test set
and proceed as usual.

Cable and Anti-Rotation Clamp Installation
The HP 08515-60003 Anti-Rotation Clamps are used to secure the RF connections
at the test ports of several Hewlett-Packard test sets. When installed, each
clamp holds the large nut that secures the test set RF port connector to the
front panel, and the RF cable connector or the front panel adapter mated with
the port connector.
Without the clamps, the test port connections may become loose after moving
the connected device and could invalidate calibrations and measurements.
NOTE: Although the anti-rotation clamps may be used with front panel adapters,
these instructions refer to an installation using the HP RF Cables. Adapter
installations will be similar.
1. Two anti-rotation clamps are included in the test set accessories box.
Remove one from the box and loosen the thumbscrew until it is almost out of
the counter-bored hole in the clamp body.
Gently push the clamp (round-hole end first) over and past the RF cable
connector you will connect to the test set RF port. The rubber O-ring in the
round end of the clamp will fit tightly over the connector. Wiggle the clamp
if necessary to get it over the connector.
Connect the cable to the test port and tighten as specified in the cable
manual. Make sure that you do not twist the cable as you attach it to the test
port. Use the torque wrench supplied with your calibration kit to tighten the
cable to no more than 90 N-cm (8 in.-lb.). 2. Important! The test set RF
connector is easily loosened so hold the RF cable throughout the rest of this
procedure. Do not allow the cable to rotate.
3. See Figure 3-7. Turn the clamp so that the thumbscrew is pointing up. From
there, turn the clamp to visually align the clamp flats with the flats on the
test port connector nut. This will minimize rotating the connector in the next
step.
NOTE: The flats may be in any orientation in respect to the front panel.

TEST SET TEMPERATURE
The processor on the A4 HP-IB assembly monitors the test set temperature with
a comparator on the A3 VT0 summing amplifier. The temperature sensor is
located on the Al4 VTO/driver assembly. If the temperature of the VTO/driver
exceeds 85°C the HP 85101 displays the “Test Set Too Hot” prompt.
TEST SET TOO HOT means turn off the test set immediately. This message is only
a prompt. It does not turn off the test set.
Determine the reason for the prompt before again subjecting the test set to
continuous use. Make sure the fan is operating properly and is not covered by
a piece of paper, etc. Make sure the fan and the side panel air exhaust has at
least 8 cm (about 3 inches) clearance, and top cover exhaust has at least 1.5
cm (about 0.5 inches) clearance.
CHECK ALL CONNECTIONS (loose, broken, crimped, etc.)
Power holes (power loss at a specific frequency) often result from faulty
connections. Check the following connections:
l Test set rear panel (including the extension links) l Cables connected to
the A3 summing amplifier and A5 Attenuator/Switch l Sampler cables l RF path
connections from rear panel to front panel
CHECK POWER SUPPLY/REGULATOR, FUSES, AND SWITCHES

TEST SET SELF-TEST INDICATORS
If the ACTIVE LED on the front panel does not light within two seconds of turn
on, or lights immediately, the test set has not passed its self-test. You can
determine what part of the self-test failed by determining which HP-IB LEDs on
the A4 assembly are lit. The table below shows the possible self-test
failures:

Two seconds after turn-on all four HP-IB LEDs should go off, and the front panel ACTIVE LED should light simultaneously. After going out briefly, the HP- IB LEDs will light according to the state of the test set. If you are using multiple test sets, the first test set in line will be the active test set until another is chosen.
If Self-test Fails to Run
If the portion of memory which contains the self-test programming is faulty,
the self-test will not run properly. The following conditions indicate that
the self-test ROMs are faulty:
0 all LEDs flash briefly and go off l all LEDs flash briefly and stay on l
ACTIVE LED goes on before HP-IB LEDs go out l ACTIVE LED does not go on at all
(check LED operation before proceeding)

Figure 5-2. Location of A3 Assembly and A3 Configuration Switch Settings
The configuration switch is on the A3 summing amplifier assembly (see Figure
5-2). It is not easy to access or reset (you must remove the top cover, a
bracket, and the A3 assembly). Therefore, unless one of the following
conditions exist, don’t change it. Reasons to suspect these switches are set
incorrectly include:
l HP 8510 turn-on frequencies are not those of test set.
l HP 8510 allows selection of two port S-parameters with a

CHECK VTO/DRIVER (LO)
There are two procedures provided to check the VTO. The first one (a) checks
the VT0 at two frequencies, the second one (b) is more thorough and checks the
VT0 at 12 frequencies throughout the VT0 range. a. Using a frequency counter
and a voltmeter, check the VT0 fundamental frequency and A3
summing amplifier output as follows: Disconnect the Test Set-IF Interconnect
cable. Using a BNC-to-snap-on cable (provided in the service kit) connect the
frequency counter to A14Jl (labeled VT0 AUX, on the VT0 board assembly). Check
that A14Jl is between 165 MHz and 195 MHz. Disconnect the cable to A3J4. The
VT0 frequency should be between 150 MHz and 190 MHz. Check that A3J4 is
between -5.6 and -6.8 Vdc. If the VT0 frequency is not correct, but the
voltage at A3J4 is correct, suspect a bad VTO. If the voltage at A3J4 is not
correct, suspect a bad A3 summing amplifier assembly (assuming the HP 85102 is
working). b. Use a power supply and a frequency counter to check the VT0 as
follows: Inject a -1 to -12V DC voltage ( in -1 volt steps) into the Al4 VT0
drive (Al4J2). Monitor A14Jl to verify that the VT0 steps through its range of
65 MHz to 300 MHz (about -21.3 MHz/volt). Figure 5-3 illustrates the
relationship of voltage at A14J2 to VT0 oscillation frequency.

Time domain response of the test set can be used to identify problems in the RF path. The plots below show typical time domain responses of the HP 8512A, 8513A, 8514A/B, and 8515A test sets. These can be used as rough standards when trying to locate a problem in the RF path. Keep in mind that the absolute location in time and absolute height of the responses will vary from test set to test set. The significant factor is the relative height of the main impulse (determined by the calibrated short) and the discontinuities. Discontinuities that may be causing a problem will usually stand out as being much greater than the typical response.
Set up the system as follows to obtain a time domain trace:
1. Connect a short or shielded open to the test set port 1.
2. Press [PRESET] [DOMAIN] [TIME BAND PASS] STIMULUS [MENU] [NUMBER OF POINTS] [4] [0] [l] [Sll] [LOG MAGI.
3. Set the START/STOP TIME, SCALE, and REF VALUE as indicated in Table 5-3, below.

Unratioed Power Test
This procedure allows you to check the output power level of each test set
sampler/mixer assembly and its associated IF amplifier alone. The normal power
level display, Sll for example, is a ratio (in this case, bl/al). The network
analyzer automatically powers and phase-locks a predefined port or ports to
make the measurement selected.
Ratioed measurements provide useful data but they can mask certain
malfunctions. Assume, for example, the task is to measure an S-parameter at a
specific power level. If the test set has a 20 dB power hole due to a faulty
RF input connector, that deficiency would be invisible (ratioed out) in a
ratioed measurement. But the data would be incorrect; it would not have been
taken at the specified power level.
Similarly, troubleshooting system faults in a ratioed measurement mode can be
deceptive. The solution is to check each channel singly, to check the power in
an unratioed mode. To do so requires specifying which port to drive power to
and which channel to achieve phase lock with. The following procedures include
steps to redefine parameters as required.
Figures 5-13 through 5-18 show which assemblies are parts of the signal path
of each channel. Realizing that some assemblies are common to two, or all
four, channels is a powerful troubleshooting tool. Figures 5-11 and 5-13
through 5-18, following these procedures, show typical traces.

Test Set Troubleshooting
HP 8514B/85l2A Test Sets
IF ANY USER CHANNEL LOOKS BAD
One or more user channels appear faulty. The question is, what is at fault?,
the source or test set or IF/ detector (HP 85102). The service adapter is a
source/test set emulator. It provides the same 20 MHz signal to the HP 85102B
as the test set and source. Thus it indicates whether the problem is in the
IF/ detector.
Equipment
l HP 85102B service adapter (provided in the HP8510B Service Manual, see
SERVICE TOOLS) l BNC to BNC cable

Test Set Troubleshooting
5-29
Service Adapter Procedure
1. Connect the HP 851026 service adapter to the HP 85102B rear panel “20 MHz
OUT” connector and the “J2 IF-DISPLAY INTERCONNECT” connector.
2. Press [PRESET] [MARKER] STIMULUS [MENU] [STEP] PARAMETER [MENU] and each
User softkey to observe the unratioed power level of the User1 through User4
channels. The traces should be flat lines, quite close to each other, as
indicated by the marker value (typically about -28+5 dB).
Service Adapter Conclusions
l If all of the channels look good (with the service adapter) and all looked
bad in the unratioed power test, the HP85101 and 85102 are working. The
problem is probably source related. Refer to the Source Tests and Service
Program sections of the Service Manual to continue troubleshooting the
problem.
l If all four User channels look bad (with the service adapter), suspect the
20 MHz signal from the A6 clock board assembly. Refer to the paragraph titled
HP85702 IF/Detector Tests in the Service Program section to verify the 20 MHz
output.
0 If one or more (but not all) channels look bad, troubleshoot the HP 85102 by
refering to the Service Program and Block Diagrams sections of the Service
Manual. Then recheck the unratioed channel power levels.
Single channel problems suggest the IF Mixer board corresponding to the User
function (channel al, bl, al, or a2) is faulty. Refer to the Overall System
Block diagram located in the Block Diagrams section of the Service Manual.
Multiple channel problems indicate the problem is most likely in the circuitry
after the IF Mixer boards (for example, the IF amplifiers or synchronous
detectors). Refer to the HP 85702A Overall Block Diagram in the Block Diagrams
section of the Service Manual.
Determine whether the failure is in the reference path or the test path.
Test the suspect board(s) using the procedures provided in the Service Program
section.
Check the IF Amplifiers and Synchronous Detectors by swapping the reference
and test board assemblies (since they are identical) and seeing if the problem
moves.

Section 6. Replaceable Parts
INTRODUCTION
This section contains information for ordering parts. Exchange Assemblies
Available describes how to order assemblies which are available on an exchange
basis. Table 6-1 is a list of manufacturers (by code number) and reference
designations. HP8514B replaceable parts are identified by Table 6-2 and
Figures 6-l through 6-7. HP8512A replaceable parts are identified by Table 6-3
and Figures 6-3, 6-4 and 6-8 through 6-10.
EXCHANGE ASSEMBLIES AVAILABLE
The items below are replaceable on a rebuilt exchange basis at a cost saving. They are not fieldrepairable. Defective assemblies must be returned for credit to realize the cost savings. Thus, assemblies required for spare parts stock should be ordered by the new assembly part number which is included in the replaceable parts list of this section. See the parts list for the orderable part numbers.

The replaceable parts lists consist of illustrations and tables. Use the
illustrations to identify the part to be ordered; use the tables to determine
the ordering information. Each table is arranged in alphanumerical order by
reference designator. The reference designator keys the part listed to the
illustration. The first part number listed is HP’s part number and may differ
from the manufacturer’s part number. The check digit serves as an error check
of the part number and should be used when ordering a part. Quantity refers to
the total number of that part in the instrument. The description is a brief
written description of the part and may be used for ordering purposes.
Manufacturers code is a five digit number assigned to each manufacturer
(identified in Table 6-l). The manufacturer part number may or may not be the
same as the HP part number.
The replaceable parts of ports 1 and 2 of the HP 8514B are identified in
Figure 6-6.
The replaceable parts of ports 1 and 2 of the HP8512B are identified in Figure
6-10. Additional center conductor and outer nut replacement information is in
Service Note 8572A-4A.
For information concerning the repair of 3.5 mm rear panel connectors, refer
to the Test Set Troubleshooting section of the HP8510B Service Manual or
Service Note 8511A-1.
