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.
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.
Note Stability of the system is not guaranteed with all antivirus software.
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 AutoCal™ 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.

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
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.

2-5 System Verification
The system verification procedures verify the measurement capabilities of the VNA, calibration kit, test port
cables, and any required adapters as a system by analyzing the measurement of artifacts that are traceable to
national standards laboratories. The procedures are automated by using the automated System Verification
Software (PVS), in conjunction with the appropriate Anritsu Calibration and Verification Kits listed in the
table below.
