Mhz To 200 Mhz Sensitivity For Hp 53181A - HP 53132A Assembly And Service Manual

Chapter 1 Performance Tests
Test 2: Channel 1 Frequency Sensitivity (HP 53181A Only)

100 MHz to 200 MHz Sensitivity for HP 53181A

Change the signal generator settings to 110 MHz at −30 dBm.
1
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 HP 53181A
Change the signal generator settings to 200 MHz at −30 dBm.
1
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.
