N5242A System Verification
Cable Substitution
The test port cables specified for the network analyzer system have been characterized for
connector repeatability, magnitude and phase stability with flexing, return loss, insertion
loss, and aging rate. Since test port cable performance is a significant contributor to the
system performance, cables of lower performance will increase the uncertainty of your
measurement. Refer to the plots in the cable tests (earlier in this chapter) that show the
performance of good cables. It is highly recommended that the test port cables be regularly
tested.
If the system verification is performed with a non-Agilent cable, ensure that the cable
meets or exceeds the specifications for the test cable specified in the previous table,
“Equipment Used in the System Verification Procedure.” Refer to the cable’s user’s guide
for specifications.
Kit Substitution
Non-Agilent calibration kits and verification kits are not recommended nor supported.
System Verification Procedure
1. If you desire printed test outputs, connect a printer to the analyzer. For the printer,
ensure that the correct driver is loaded and the printer is defined as the default printer.
Refer to the embedded help in the analyzer for printer setup. Let the analyzer warm up
for at least 90 minutes.
2. Insert the verification kit disk into the analyzer disk drive.
3. Press UTILITY , then , then . The
