1-4 Basic Maintenance

Maintain Operating System Integrity
The Microsoft Windows Embedded operation system on the ShockLine MS46322A/B is configured for optimum performance when the instrument leaves the factory. To maintain the system’s operating integrity, follow proper Windows shutdown procedure and DO NOT modify the operating system configuration, the firewall settings, the system registry, the solid state drive partitions, or the Anritsu user account.
Antivirus Protection Best Practices
If the VNA is attached to a network, best practices recommend installing antivirus software. Anritsu recommends connecting the instrument only to a secure network. The user assumes the responsibility to provide virus protection because this is not supplied with the instrument. Contact your network administrator for information about your network security and antivirus protection policies.
Note Stability of the system is not guaranteed with all antivirus software.

Windows OS Updates
Not all Microsoft updates are compatible with the ShockLine MS46322A/B VNA and, if installed, may affect the performance of the instrument.

Caution

Changing some of the default Windows settings may cause a loss of instrument control or undesired instrument behavior. Changing the Windows Regional and Language Options settings may cause unstable menu operation. These settings must be maintained as English (United States) as is set at the factory by default.

Chapter 2 — MS46322A Performance Verification
2-1 Introduction to Performance Verification
This chapter provides procedures to be used to verify the performance of ShockLine MS46322A.
There are many levels to the concept of VNA “verification”.
On the explicit VNA hardware level are operational checkout items such as port power and noise levels.
On the calibrated instrument level (which includes the VNA and the calibration kit or AutoCalTM Automatic Calibrator) are the system residual specifications (corrected directivity, source match, load match, and tracking) which are measured using airlines (traceable impedance standards).
An intermediate level which can look at overall system behavior (VNA, calibration kit, cables, environment) in a traceable fashion is through the use of a verification kit. While not intended for day-to-day use, the verification kit can provide a periodic check on system behavior without going through the rigor needed for full residual analysis (which can usually be done less often).
While there are many ways of verifying VNA performance, sometimes simpler procedures are desired. The use of verification kit, available from Anritsu, is a simpler method of verifying the measurement capabilities of the instrument by analyzing the measurement of artifacts that are traceable to International System of Units (SI) via national metrology institutes.
2-2 VNA Traceability and Uncertainty
Vector network analyzers (VNAs) are precision instruments for making high frequency and broadband measurements in devices, components, and instrumentations. The accuracy of these measurements is affirmed by demonstrated and adequate traceability of measurement standards. Metrological traceability, per International Vocabulary of Metrology, JCGM 200:2012, is property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty. For the accuracy of VNAs and quality assurance by users, two standard approaches were created to ensure sound metrology traceability. One is to construct tight uncertainty budget and specifications in three tiers from the ground up, and the other is to develop a calibration hierarchy for systematic verification. The three-tier process is depicted in the sections below.
First Tier of Uncertainty The VNA Calibration
A traceable VNA itself requires proper calibration for several key quantities, e.g., frequency, power level, and high level noise, via traceable standards to the SI units. Each contributing uncertainty was evaluated at the time of instrument calibration.
The inception of a precision VNA is accuracy-enhanced 50 ohm impedance, which is characterized in lieu of coaxial transmission lines all with proper propagation properties throughout the whole measurement systems including the device-under-test. A transmission line for VNAs is best represented by a coaxial airline, which was precisely selected and machined based on the electromagnetic properties such as conductivity, skin depth, and etc. Therefore, the dimensional measurement accuracy of the airline gives out the first tier of measurement uncertainty of impedance quantity.

2-2 VNA Traceability and Uncertainty

MS46322A Performance Verification

Second Tier of Uncertainty Systematic Measurement Errors
The second tier of uncertainty, corrected or residual uncertainty, is the result of the accuracy enhancement of VNA calibration to remove systematic errors. Systematic measurement errors are components of measurement error that in replicate measurements remains constant or values in a predictable manner. This accuracy enhancement is usually the function of calibration kits. The choice of calibration kits used will dictate the level of uncertainties for the intended measurements or applications.

Third Tier of Uncertainty Random Measurement Error
The third tier of uncertainty is random measurement error that in replicate measurements varies in an unpredictable manner. The examples are connector repeatability, cable stability, and etc. Random measurement error equals measurement error minus systematic measurement error.

Standards and Verification
Most often instrument end users demand system verifications in order to provide quality check or assurance. This is accomplished by utilizing a set of known or characterized devices, e.g., verification kit, for comparison. It can also be done by using devices that are different from the calibration kit. The calibration hierarchy of verification uncertainty is built through unbroken chain comparisons with the national standards, as illustrated in Figure 2-1.

2-3 Electrostatic Discharge Prevention

2-3 Electrostatic Discharge Prevention
A VNA is a precision electronic instrument consisting of components and/or circuitries that are sensitive to electrostatic discharge (ESD). In order to prevent intrusion of electrostatic charge and mitigate risk of costly ESD damage, it is important to take preventive measures to protect against ESD before and during usage. For example, prior to connecting a test port cable to the VNA test port, take steps to eliminate the static charges built up on the test port cable. This can be done by terminating the open end of the cable with the short from the calibration kit and then grounding the outer conductor of the connector on the cable.

2-4 Calibration and Measurement Conditions
The surrounding environmental conditions and the condition and stability of the test port connectors, thru cable, and calibration kit determine system measurement integrity to a large extent.
These are all user controlled conditions, and as such, should be evaluated periodically for impact on system performance.
The standard conditions specified below must be observed when performing any of the operations in this chapter both during calibration and during measurement.
· Warm-up Time: · 30 minutes
· Environmental Conditions · Temperature · 23 °C ± 3 °C, with < 1 °C variation from calibration temperature · Relative Humidity · 20-50% recommended
Using best measurement practices and maintaining environmental conditions within specified limits during calibration and measurements are critical requirements for performing system verification that involves reliable high- quality measurements with associated measurement uncertainties. Note that both of these key factors affect the measurement uncertainty.

MS46322A Performance Verification

2-5 System Verification

The System Performance Verification Software guides the user to perform a full 12-term calibration on the VNA using the appropriate calibration kit, measure the S-parameters of the impedance transfer standards in the verification kit, and confirm that the measured values are within the specified measurement uncertainty.
The verification kit consists of four impedance transfer standards, and each are supplied with S-parameter data. Each standard verifies a primary S-parameter with uncertainty windows provided at each data point as follows:
· 20 dB Attenuation Standard S21, S12 Magnitude and Phase · 50 dB Attenuation Standard S21, S12 Magnitude and Phase · 50 Ohm Air Line Standard S21, S12 Phase · 25 Ohm Mismatch (Beatty) Standard S11, S22 Magnitude Pass/Fail status of the measurements is displayed on the computer. The software can also provide hardcopy (printout) of the test reports which include the measured data, the measurement uncertainties, and the Pass/Fail status.

Verification Result Determination
The software verification process compares the measured S-parameter data of the impedance transfer standards against the original standard (characterization) data for those devices that was obtained using the Factory Standard Vector Network Analyzer (at Anritsu).
The Factory Standard Vector Network Analyzer system is traceable to International System of Units (SI) through the impedance Standards of the Anritsu Calibration laboratory. These standards are traceable to International System of Units (SI) through precision mechanical measurements, microwave theory impedance derivation methods, and electrical impedance comparison measurements.
At each frequency point, the verification measurement is compared to the characterization measurement in the context of the uncertainties. If the delta between the two measurements is consistent with the uncertainty window, the measurement is considered acceptable at that point.
The metric of comparison, termed En, is a check to see if the measurement differences are consistent with the uncertainty windows of both the characterization and the verification measurements. The quantity is shown in the following formula:

Equation 2-1

———-X—–x–y—c–h—a—r——-X—–x–y–v—e—r———Uxychar2 + Uxyver2

where:
· The numerator contains the magnitude or phase of S-parameters measured during characterization (by Anritsu) and during verification (by the user).
· The denominator contains the respective uncertainties.
These uncertainties are calculated based on the VNA, the calibration kit, and repeatability. If this quantity En is less than 1, then the measurements during the two phases are within the overlap of the uncertainties and one can consider the measurements “equivalent” and, in some sense, verified.
The quality of the verification results is very dependent on the degree of care taken by the user in maintaining, calibrating, and using the system. The most critical factors are:
· The stability and quality of the devices in the calibration kit and verification kit.
· The condition of the VNA test port connectors and test port cables.

The System Performance Verification Software guides the user to perform a full 12 Term calibration on the VNA using the appropriate calibration kit, measure the S-parameters of the impedance transfer standards in the verification kit, and confirm that the measured values are within the specified measurement uncertainty.
The verification kit consists of four impedance transfer standards and each are supplied with S-parameter data. Each standard verifies a primary S-parameter with uncertainty windows provided with each data point as follows:
· 20 dB Attenuation Standard S21, S12 Magnitude and Phase · 50 dB Attenuation Standard S21, S12 Magnitude and Phase · 50 Ohm Air Line Standard S21, S12 Phase · 25 Ohm Mismatch (Beatty) Standard S11, S22 Magnitude Pass/Fail status of the measurements is displayed on the computer. The software can also provide hardcopy (printout) of the test reports which include the measured data, the measurement uncertainties, and the Pass/Fail status.

3-7 System Verification Procedure

MS46322B Performance Verification

The metric of comparison, termed En, is a check to see if the measurement differences are consistent with the uncertainty windows of both the characterization and the verification measurements. The quantity is shown in the following formula:

———-X—–x–y—c–h—a—r——-X—-x—y–v—e—r———Uxychar2 + Uxyver2

Equation 3-1
where:
· The numerator contains the magnitude or phase of S-parameters measured during characterization (by Anritsu) and during verification (by the user).
· The denominator contains the respective uncertainties. These uncertainties are calculated based on the VNA, the calibration kit, and repeatability. If this quantity En is less than 1, then the measurements during the two phases are within the overlap of the uncertainties and one can consider the measurements “equivalent” and, in some sense, verified.
The quality of the verification results is very dependent on the degree of care taken by the user in maintaining, calibrating, and using the system. The most critical factors are:
· The stability and quality of the devices in the calibration kit and verification kit. · The condition of the VNA test port connectors and test port cables. · The pin depths of all connectors and the proper torquing of connections. These same factors also affect
the VNA measurement quality. Consult the reference manual supplied with Anritsu Calibration Kits and Verification Kits for proper use, care, and maintenance of the devices contained in these kits.

3-7 System Verification Procedure
The System Verification procedure is described below. The procedure assumes that the System Verification Software (PVS) has been installed to an External Personal Computer running Microsoft Windows Operating System and the National Instruments VISA runtime.

Chapter 5 — Troubleshooting

5-1 Introduction
This chapter provides information about troubleshooting tests that can be used to check the MS46322A/B Vector Network Analyzer for proper operation. These tests are intended to be used as a troubleshooting tool for identifying the faulty components and checking the functionality of internal components and sub-assemblies in the MS46322A/B VNA.
Only qualified service personnel should replace internal assemblies. Major subassemblies that are shown in the replaceable parts list are typically the items that may be replaced.
Because they are highly fragile, items that must be soldered may not be replaced without special training. Removal of RF shields from PC boards or adjustment of screws on or near the RF shields will de tune sensitive RF circuits and will result in degraded instrument performance.

5-2 General Safety Warnings
Many of the troubleshooting procedures presented in this chapter require the removal of instrument covers to access sub-assemblies and modules. When using these procedures, please observe the warning and caution notices.

Warning

Hazardous voltages are presented inside the instrument when AC line power is connected. Before removing any covers, turn off the instrument and unplug the AC power cord.

Caution

Many assemblies and modules in the MS46322A/B VNA contain static-sensitive components. Improper handling of these assemblies and modules may result in damage to the assemblies and modules. Always observe the static-sensitive component handling precautions.

5-7 Troubleshooting Measurement Problems

5-7 Troubleshooting Measurement Problems
If the MS46322A/B measurement quality is suspect, the following paragraphs provide guidelines and hints for determining possible quality problems.

VNA Measurement Quality
The quality of MS46322A/B VNA measurements is determined by the following test conditions and variable: · The condition of the MS46322A/B. · The quality and condition of the interface connections and connectors. · The quality and condition of the calibration components, thru cables, adapters and fixtures. · The surrounding environmental conditions at the time of the measurement. · The selection and performance of the calibration for the DUT being measured.

Checking Possible Measurement Problems
When determining possible measurement problems, check the following items:
1. Check the DUT and the calibration conditions:
a. Ensure that the Calibration Components Coefficients data has been installed into the VNA for the Calibration Kit in use.
b. Ensure that the proper calibration was done for the device being measured:
· For high insertion-loss device measurements, the calibration should include isolation, high number of averages, and narrow IF Bandwidth setting during calibration.
· For high return-loss device measurements, a high quality precision load should be used during calibration.
c. Check the condition of DUT mating connectors and their pin depth.
d. If possible, measure an alternate known good DUT.
e. Check if the environment is stable enough for the accuracy required for the DUT measurement.
· The VNA should not be subjected to variations in temperature. · The VNA should not be placed in direct sun light or next to a changing cooling source, such
as a fan or air conditioning unit. 2. Check the calibration using known good components from the calibration kit. If measurements of these
devices do not produce good results, try the following:
a. Check Thru Cable stability including condition and pin depth. Replace with a known good cable, if necessary.
b. Check condition and pin depth of calibration kit components. Replace with known good components, if necessary.
c. Check condition and pin depth of test port adapters. Replace with known good ones if necessary.
3. Check the system performance as described in Chapter 2 — MS46322A Performance Verification and Chapter 3 — MS46322B Performance Verification
