Step 8. Calculate the following formula:
Test Result (Hz) = frequency value Ch2 - Frequency value Ch1
Step 9. Verify that the test result is 500 Hz ± 150 Hz.
Step 10. If the check failed, a failure in the Oven Ch1 is suspected.
To Check the Oven Ch2
Procedure
This check is performed using a frequency counter and a power meter.
Step 1. Connect the frequency counter to the Ext Ref Out connector, and then verify that the
frequency value is 10 MHz ± 50 Hz.
Step 2. Connect the power meter to the Ext Ref Out connector, and then verify that the power
value is 2.5 dBm ± 3 dB.
Step 3. If the check failed, a failure in the Oven Ch2 is suspected.
