PNA Series Microwave Network Analyzers Tests and Adjustments
E8362B, E8363B, E8364B System Verification
Performing System Verification
The following verification procedure is automated by the analyzer firmware. For each
verification device, the analyzer reads a file from the verification disk and sequentially
measures the magnitude and phase for all four S-parameters.
IMPORTANT
For system verification to perform correctly, it is NECESSARY that the
verification devices be measured with their female connectors connected to
Port 1 and their male connectors connected to Port 2.
NOTE
The following procedure, and the connection prompts given, assumes only one
female-to-female cable connected to Port 2. However, this procedure can also
be performed with the addition of a female-to-male cable connected to Port 1.
NOTE
Although the performance for all four S-parameters are measured, the S
11
and S
22
phase uncertainties for the attenuators and airlines are less
important for verifying system performance. Therefore, the limit lines will
not appear on the printout.
Equipment Supported by the System Verification Procedure
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 to 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 RF cable specified in the above table,
“Equipment Supported by 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.
