HP 181A manual MHz to 200 MHz Sensitivity for HP 53131A/132A

Chapter 1 Performance Tests

Test 3: Channels 1 and 2 Frequency Sensitivity (HP 53131A/132A Only)

10Record 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

1Leave the signal generator connected to Channel 2. Change the signal generator settings to 200 MHz at −30 dBm.

2On the Counter, press Run key.

3Increase 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).

4Sweep 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).

5Record the actual reading in the Performance Test Record (Test 3, Line 3).

6Connect the signal generator to Channel 1.

7On the Counter, press Freq & Ratio key until Frequency 1 is displayed.
