Why does my E6651A fail Source Modulated Power Level Accuracy in TME?
A compatibility issue exists between E6651A firmware versions 126.96.36.199/188.8.131.52 and TME release 1.0.
The issue affects the Source Modulated Power Level Accuracy test, causing all datapoints to fail by a significant amount. The test limit is ±1.4dB, and failures in the region of +3dB are common with this issue.
The workaround for this issue is to downgrade the firmware to 184.108.40.206/220.127.116.11, test the E6651A, and upgrade the firmware back to 18.104.22.168/22.214.171.124 once the procedure is complete.
This issue has been logged in our software quality system, and will be fixed in due course.
