End of Procedure
1 Reference spectrum analyzer phase noise performance specification to ensure that noise floor of analyzer
does not limit analyzer range.
Use Datasheet 2 below to record the results of the spectral purity test.
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.
