200 MHz to 225 MHz Sensitivity for Agilent 53131A/132A
1 Leave the signal generator connected to Channel 1. Change the signal generator
settings to 225 MHz at −30 dBm.
2 On the Counter, press Run key.
3 Increase the power level by 0.1 dB steps until the Counter displays a stable
reading of 225 MHz.
The Counter should read 225 MHz when the input signal level is
≤ −15.0 dBm (40 mVrms).
4 Sweep the signal generator frequency from 225 MHz to 200 MHz.
The Counter should read frequencies from 225 MHz to 200 MHz when the input
signal level is ≤ −15.0 dBm (40 mVrms).
5 Record the actual reading in the Performance Test Record (Test 3, Line 5).
6 Connect the signal generator to Channel 2.
7 On the Counter, press Freq & Ratio key until Frequency 2 is displayed.
8 Repeat steps 1 through 4 for Channel 2.
9 Record the actual reading in the Performance Test Record (Test 3, Line 6).
10 Disconnect the test setup.
