PNA Series Microwave Network Analyzers Tests and Adjustments
E8362B, E8363B, E8364B Preliminary Checks
Preliminary Checks
Preliminary checks include the following:
• “The Operator’s Check” on page 3-11
The operator’s check tests the network analyzer’s basic functionality of the source,
switch, step attenuators, and receivers.
• “The Test Port Cable Checks” on page 3-13
The test port cable checks are not required, but are recommended to verify the
performance of the test port cables before performing the verification test.
The Operator’s Check
NOTE
To achieve the maximum system stability, allow the analyzer to warm up for
at least 90 minutes before performing the Operator’s Check.
The operator’s check is a software driven test that checks the basic operation of the
assemblies in the Port 1 and Port 2 signal paths. By performing the operator’s check, the
following are determined:
• repeatability of the RF test port switch
• attenuation ranges of all installed attenuators
• calibration of the receivers
• frequency response of the receivers
• phase lock and leveling
• noise floor and trace noise
Accessories Used in the Operator’s Check
Performing the Operator’s Check
1. From the System menu, point to Service, and then click Operator’s Check.
2. In the PNA Operator’s Check dialog box (refer to Figure 3-3), under Configure, select
either Prompt for attachment of Short/Open, to pause at each step in the process to
allow moving the short/open to the appropriate port, or Shorts/Opens are attached to
ALL ports, to run through the test without stopping. Shorts and opens can be mixed on
the test ports.
