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.
Although the performance for all four S-parameters are measured, the S

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,
