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
uncertainties for the attenuators and airlines are less important for verifying system
performance. Therefore, the limit lines will not appear on the printout.

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,

Kit Substitution
Non-Agilent calibration kits and verification kits are not recommended nor supported.
