PNA Series Microwave Network Analyzer System Performance Tests and Checks
N5250A 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 a system verification result that represents the current performance of the system, save the
five resulting files to D:\sysver results.
