11.
Set the AM Sensitivity of the UUT to 50 % and repeat steps 8 through 9 for each of the test frequen-
cies in Datasheet 6, recording the AM depth for each measurement in the appropriate column.
12.
Set the AM Sensitivity of the UUT to 75 % and repeat steps 9 and 10 for each of the test frequencies
in Datasheet 6, recording the AM depth for each measurement in the appropriate column.
13.
After you have entered all of the test results onto the datasheet, compare the test results with the
following to verify compliance of the 2500B:
End of Procedure
NOTE:
In the datasheet below, test the 2500B only at the frequencies within the range of your specific model of 2500B.
For frequencies not within your instrument’s range, enter “N/A” in the test results column(s) of the datasheet.
