Preliminary Checks
Preliminary checks include the following:
- The Operator’s Check
The Operator’s Check tests the basic functionality of the source, switches,
and receivers in the network analyzer.
- “The Test Port Cable Checks” on page 2-14
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
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 internal attenuators
- calibration of the receivers
- frequency response of the receivers
-phase lock
-noise floor and trace noise
- various voltages throughout the network analyzer
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
1. On the soft front panel, click Utility > System > Service > Operator’s
Check.
2. In the PXI Operator’s Check dialog box (refer to Figure 2-3), under
Configure, click 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.
In most cases, the short/open is not required since the analyzer test port’s
female connector acts an “open.” However, if the test fails, confirm the
failure with a short/open attached.
Allow the network analyzer to warm up for at least 15 minutes before
performing the Operator’s Check.
