Chapter 1 Performance Tests
Test 3: Channels 1 and 2 Frequency Sensitivity (Agilent 53131A/132A
Only)
Assembly-Level Service Guide 1-25
1
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 Agilent 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.
8 Repeat steps 1 through 4 for Channel 1.
9 Record the actual reading in the Performance Test Record (Test 3, Line 4).
