STEP 5. Verify Operation of the Network Analyzer Modules
The Operator’s Check
NOTE Allow the network analyzer modules to warm up for at least 15 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 all of the measurement port signal paths. By performing
the operator’s check, the following are determined:
• attenuation ranges of all installed attenuators
• calibration of the receivers
• frequency response of the receivers
•phase lock
• noise floor and trace noise
• various voltages throughout the network analyzer module
Accessories Used in the Operator’s Check
Male short(s) or open(s) from a 3.5 mm calibration kit.
Performing the Operator’s Check
NOTE Perform the Operator’s Check on each network analyzer module in your configuration.
1. On your PC screen, click the Network Analyzer icon.
2. Select a network analyzer module in your configuration.
3. On the soft front panel, select Utility > System > Service > Operator’s Check.
4. In the PXI Operator’s Check dialog box (refer to Figure 1-11 on page 22),
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.
5. Select Begin.
6. If shorts and opens are not connected to all ports, you will be prompted to
connect them as they are needed.
7. The result of the operator’s check will be shown as a PASS or FAIL next to
each test (refer to Figure 1-11 on page 22.
