Performance Tests and Checks
System Performance Verification
Improving the Verification Results
IMPORTANT Inspect all connections. Do not remove the test port cable from the analyzer
test port. This will invalidate the calibration that you performed earlier.
1. Disconnect and clean the device that failed the verification measurement.
2. Reconnect the device making sure that all connections are carefully torqued.
3. Measure the device again using the previous calibration.
4. If the device still fails the verification measurement, repeat the full system verification process
including calibration.
Saving Verification Results
When you have system verification results that represent current system performance, save the
results files (five files for each port pair) in the appropriate subdirectory under D:\sysver results.
