Operational Check with Cal Kit
1-
Figure 40
Reflection Tracking Trace (Port 5-8)
Response from 10 MHz to 500 MHz is normal due to the analyzer’s couplers
in comparison to the test set bridges. The bridges have more gain in the
coupled RF path.
Verifying a Cal Kit Operational Check Failure
If your test results fail the Cal Kit Operational Check Reflection Tracking limits,
verify the following:
1.
Ensure the test set is On and connected properly to the analyzer.
2.
Check all appropriate analyzer and test set connectors for damage,
cleanliness, and proper torques.
3.
Repeat the relevant 1-Port calibrations using another ECal or mechanical
standard.
4.
Verify that the analyzer is operating properly and meeting its published
specifications. If the analyzer is connected to the test set it will fail the
Operational Check. Refer to
“Network Analyzer Requirements” on page 4
ECal Confidence Check
The following procedure is a method to verify the accuracy of a 1-Port
calibration performed with mechanical standards or an ECal module. To
perform this check, the test port of the ECal module must connect directly to
the Test Port being verified (without adapters).
