Preliminary Checks
Preliminary checks include the following:
• “The Operator’s Check” on page 3-10
The operator’s check tests the network analyzer’s basic functionality of the source, switch, and
receivers.
• “The Test Port Cable Checks” on page 3-12
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.
3. Click Begin.
