System Verification
Performing System Verification
The following verification procedure is automated by the network analyzer
firmware. The process for the verification is:
- connect cables to the analyzer test ports
-perform a calibration or recall a recent calibration
- run the system verification program for the verification devices
Each time through the verification process, you are prompted to make
necessary connections and perform or recall a calibration as part of performing
the verification. If you select to perform a calibration, you are guided through
the calibration procedure. This part of the process can be eliminated if you
choose to load an existing recent calibration. If necessary, refer to the network
analyzer’s Help system for information on storing and recalling calibrations.
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.
Equipment Used in the System Verification Procedure
For system verification to perform correctly, it is NECESSARY that the
verification devices be measured with their female connectors connected
to the network analyzer’s Port 1 and male connectors to Port 2.
Although the performance for all 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.
