5 Check to see if the analyzer is phase locking to the external CW signal:
6 On the external source, press CW, 50, MHz/µ.
7 On the analyzer, press 50, M/µ.
8 Repeat
In Case of
Difficulty
1 Be sure the external source power is set within 0 to –25 dBm.
2 Make sure the analyzer's "Ext Source Auto" feature is selected. In addition,
3 Verify that all connections are tight.

3. Test Port Output Power Accuracy
• If the analyzer displays any phase lock error messages, write "unlock" in the
"Performance Test Record" for the set CW signal.
• If the analyzer does not display any phase lock error messages, write "lock"
in the "Performance Test Record" for the set CW signal.
Step 5

listed in the "Performance Test Record." For analyzers with Option 006, change
the power sensor to the Agilent 8481A for frequencies above 4 GHz.
verify that the analyzer is set to measure its input channel R.
