100 MHz to 200 MHz Sensitivity for Agilent 53181A
1 Change the signal generator settings to 110 MHz at −30 dBm.
2 Increase the power level by 0.1 dB steps until the Counter displays a stable 110
MHz reading.
The Counter should read 200 MHz when the input signal level
is ≤ −17.5 dBm (30 mVrms).
3 Sweep the signal generator frequency from 100 MHz to 200 MHz.
The Counter should read frequencies from 100 MHz to 200 MHz when the input
signal level is ≤ −17.5 dBm (30 mVrms).
4 Record the actual reading in the Performance Test Record (Test 2, Line 2).
200 MHz to 225 MHz Sensitivity for Agilent 53181A
1 Change the signal generator settings to 200 MHz at −30 dBm.
2 Increase the power level by 0.1 dB steps until the Counter displays a stable 200
MHz reading.
The Counter should read 200 MHz when the input signal level is
≤ −15.0 dBm (40 mVrms).
3 Sweep the signal generator frequency from 200 MHz to 225 MHz.
The Counter should read frequencies from 200 MHz to 225 MHz when the input
signal level is ≤ −15.0 dBm (40 mVrms).
4 Record the actual reading in the Performance Test Record (Test 2, Line 3).
5 Disconnect the test setup.
