Performance Tests and Checks PNA Series Microwave Network Analyzer System

System Preparation and Analyzer Warm Up
NOTE To achieve the maximum system stability, allow the analyzer to warm up for at least 90
minutes.
Complete the procedures in Chapter 3 , “System Installation,” to assemble and configure the system. After
you press the Preset button, the PNA should display a frequency range of 10 MHz to 110 GHz.
Torquing Connections
All connections made during the System Check and System Performance Verification procedures should be
carefully torqued using the tools provided in the 85059A kit.
Long Term Storage of Test Results
It is recommended that you store results from the System Check and the System Performance Verification
procedures for future reference. Prior results can be useful when evaluating changes in system
performance. After completing a successful test process that accurately represents the system
performance, store the test result files in the directory D:\sysver results. It may be necessary to create this
directory if it does not already exist.
Protect Against Electrostatic Discharge (ESD)
This is important. If not properly protected against, electrostatic discharge can seriously damage your
analyzer, resulting in costly repair.
CAUTION To reduce the chance of electrostatic discharge, follow all of the recommendations outlined
in “Electrostatic Discharge Protection” on page 1-4, for all of the procedures in this chapter.
