Test 3: Channels 1 and 2 Frequency Sensitivity (HP 53131A/132A Only)
Record the actual reading in the appropriate place in the
Performance Test Record (Test 3, Line 2).
If you are testing a Counter with front-panel terminals (Standard),
record the reading on Line 2 of the Standard portion of the test record.
If you are testing a Counter with rear terminals (Option 060),
record the reading on Line 2 of the Option 060 portion of the test record.
The remaining sensitivity procedures are NOT required for Counters that
contain Option 060 Rear Terminals; thus, this completes the sensitivity
portion of the Frequency Performance Test. Go to the Frequency Accuracy
Test on page 1-27.

100 MHz to 200 MHz Sensitivity for HP 53131A/132A

Leave the signal generator connected to Channel 2. Change the
signal generator settings to 200 MHz at −30 dBm.
On the Counter, press Run key.
Increase the power level by 0.1 dB steps until the Counter
displays a stable 200 MHz reading.
The Counter should display 200 MHz when the input signal level is
≤ −17.5 dBm (30 mVrms).
Sweep the signal generator frequency from 200 MHz to 100 MHz.
The Counter should read frequencies from 200 MHz to 100 MHz when the
input signal level is ≤ −17.5 dBm (30 mVrms).
Record the actual reading in the Performance Test Record
(Test 3, Line 3).
