Connecting the instrument to your PC Before connecting your APx517 instrument
to your PC, install the APx500 measurement software as described above.
Connecting the instrument prior to software instal-
APx517 B Series Acoustic Audio Analyzer: Installation
lation may cause Windows to select an incorrect USB driver for the instrument.
USB driver selection The measurement software communicates with the APx517
using a USB 2.0 interconnection. Once the software is successfully installed,
connect one end of the USB cable to a USB 2.0 port on the PC, and the other
end to the PC INTERFACE port on the rear of the APx517. We strongly recommend
that you use the USB cable included with your instrument (AP part number
CABAPSI). We have tested other USB cables that perform poorly.
Note: Some PCs have optional USB ports on the front of the PC, or on extension
brackets on the rear. In many cases these convenience ports have compromised
performance due to the extra cable length within the PC. We recommend using
USB ports directly connected to the PC motherboard, typically at the rear of
the PC.
Connect the APx517 mains power cord to the instrument and to a source of ac
mains power. See the Mains Power and Fusing section that follows for more
information about mains connections.
Turn the instrument on by rocking the mains power switch to ON ( | ). The
mains power switch is located in the power entry module on the rear of the
APx517. Windows will detect the presence of the APx517 on the USB port and
will open the Hardware Update Wizard to search for the correct software
driver. Select “Install the soft-
APx517 B Series Acoustic Audio Analyzer: Installation
ware automatically.” Windows will find the Audio Precision driver software
installed with APx500 and connect to the APx517.
Launch APx500 by double-clicking on the installed shortcut. With the APx517
connected, you may be asked to update the instrument firmware during the first
launch of the measurement software. APx500 will start, and in a short time you
will be presented with the opening screen. Refer to the APx500 User’s Manual
for more information about making measurements.
The APx500 User’s Manual is available as a PDF on the APx500 Application Disc
and online at ap.com; a hard-copy version can be ordered from Audio Precision
or your local distributor.
Mains Power and Fusing
Connect the APx517 mains power cord to the instrument and to a source of ac
mains power. Turn the APx517 on by rocking the mains power switch to ON ( | ).
The mains power switch is located in the power entry module on the rear of the
analyzer.
Connecting your instrument to the electrical mains supply
A n APx517 must be connected to a 5060 Hz alternating current (ac) electrical
mains supply. The minimum voltage is 100 Vac; maximum voltage is 240 Vac. Use
only adequately rated detachable mains power cords.
25
The analyzer is fitted with a universal power supply that does not require
voltage configuration or change of fuse type to accept mains voltages within
the specified range.
Removing and installing mains fuses
For all rated voltages, use two mains fuses of type
· 4 A T/SB (5×20 mm) 250 V.
Use only certified fuses of the appropriate specifications.
To remove the mains fuse carrier module, refer to the figures below and
proceed as follows:
Remove the mains power supply cord from the connector on the power entry
module, located on the APx517 rear panel. The mains fuse carrier module is
part of the power entry module, below the power switch.
Insert a small screwdriver into the slot at the bottom of the power entry
module as shown in figure 1, and pry open the hinged door to reveal the red
mains fuse carrier module. Lift the fuse carrier module with the screwdriver
as shown in Figure 2, and then pull it out of the power entry module using
your fingers. The two mains fuses are loosely mounted within the fuse carrier
module; take care not to let them fall.

Modular Headphone Connector Panels
The APx517 has field-swappable modular headphone output connector panels that
fit in the headphone amplifier output bay. The panels are available with one
of three connector types:
· 1/4 inch jack
· 3.5 mm jack
· Dual BNC
If changes in testing requirements require a different headphone connector,
the headphone panel can be replaced. Additionally, as headphone connectors
wear out from the repeated plugging and unplugging of cables during production
test, they can be replaced.
Removing a Modular Headphone Connector Panel
To remove the headphone connector panel from the APx517 chassis:
1. Loosen the two thumbscrews to release the connector panel from the APx517
chassis. (See Figure 5)
2. Holding the thumbscrews, pull the panel straight out from the APx517
chassis. The panel slides on a slotted rail on each side of the panel opening
in the chassis.
Figure 5
Installing a Modular Headphone Connector Panel
To install the headphone connector panel in the APx517 chassis:
1. Carefully remove the headphone connector panel from the protective
packaging.
2. Holding the connector panel by the panel face or by the thumbscrews, align
the sides of the panel with the panel rail slots on each side of the panel bay
and insert the connector panel straight into the chassis. (See Figure 5)
APx517 B Series Acoustic Audio Analyzer: Installation
27
If the connector panel does not slide in smoothly, check to ensure that the
panel is inserted straight in the chassis and that the left and right edges
are sliding in the panel rail slots in the panel bay.
3. Slide the panel completely into the APx517 chassis so that the panel face
is flush with the chassis front panel.
4. Tighten the thumbscrews so that they hold the panel securely against the
chassis.
If the thumbscrews are not secure, unplugging a headphone connector can loosen
the panel connection and cause inconsistent measurement results.

This illustration shows the PDM module, model 236.
The PDM option provides a complete solution for addressing circuits or devices
with a PDM input or output. The PDM signal output consists of an APx generator
audio signal, interpolated by a broad choice of oversampling ratios, and
modulated into a 1-bit PDM bitstream. A 4th-order modulator is the default; a
5th-order modulator can be selected. The PDM Option also provides a signal
input with its associated clock connection. The input accepts a 1bit PDM
bitstream, which is then decimated by one of a wide range of decimation ratios
and filtered into baseband audio at the Decimated Rate. The input bitstream
can also be analyzed directly (before decimation) in the Signal Analyzer to
view out-of-band components.
These specifications cover the digital input and output functions of the Audio
Precision PDM interface for the current version, model 236.

NP0020.00046 rev 000 November 2019
This illustration shows the PDM 16 module, model 243, and PDM 16 remote
interface pod.
The PDM 16 option provides a solution for addressing circuits or devices with
multiple PDM outputs. The PDM 16 option provides up to 16 acquisition channels
that connect through the module’s PDM 16 remote interface pod. All 16 channels
can be measured simultaneously to provide sample-accurate interchannel
information. The input accepts 1-bit PDM bitstreams, which are then decimated
by one of several available decimation ratios and filtered into baseband audio
at the Decimated Rate. The PDM 16 also provides a variable Vdd supply (0.0
V-3.6 V, 50 mA max.) and a bit clock that can be configured as an input or an
output.
The PDM 16 remote interface pod provides a 40-pin, 0.1″ (2.54mm) pitch IDC
connector as an interface to PDM MEMS microphones. All signal pins are
provided with individual, shared grounds. All clock outputs are redundant but
individually buffered to drive multiple clock inputs if required. The Vdd
output provides DC power, if required, for the device under test. The 8 data
input pins can be used to interface up to 16 microphones simultaneously. The
input is compatible with commonly available IDE / parallel ATA I/O cables.
