Chapter 1 Performance Tests
Test 3: Channels 1 and 2 Frequency Sensitivity (HP 53131A/132A Only)
Assembly-Level Service Guide 1-25
1
10 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.
NOTE
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
1 Leave the signal generator connected to Channel 2. Change the
signal generator settings to 200 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 200 MHz reading.
The Counter should display 200 MHz when the input signal level is
≤−
17.5 dBm (30 mVrms).
4 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).
5 Record the actual reading in the Performance Test Record
(Test 3, Line 3).
6 Connect the signal generator to Channel 1.
7 On the Counter, press Freq & Ratio key until
Frequency 1
is
displayed.
