Chapter 1 Performance Tests

Test 2: Channel 1 Frequency Sensitivity (Agilent 53181A Only)

1-54 Assembly-Level Service Guide

100 MHz to 200 MHz Sensitivity for Agilent 53181A

1 Change the signal generator settings to 110 MHz at −30 dBm.

2 Increase the power level by 0.1 dB steps until the Counter displays a stable 110

MHz reading.

The Counter should read 200 MHz when the input signal level

is ≤ −17.5 dBm (30 mVrms).

3 Sweep the signal generator frequency from 100 MHz to 200 MHz.

The Counter should read frequencies from 100 MHz to 200 MHz when the input

signal level is ≤ −17.5 dBm (30 mVrms).

4 Record the actual reading in the Performance Test Record (Test 2, Line 2).

200 MHz to 225 MHz Sensitivity for Agilent 53181A

1 Change the signal generator settings to 200 MHz at −30 dBm.

2 Increase the power level by 0.1 dB steps until the Counter displays a stable 200

MHz reading.

The Counter should read 200 MHz when the input signal level is

≤ −15.0 dBm (40 mVrms).

3 Sweep the signal generator frequency from 200 MHz to 225 MHz.

The Counter should read frequencies from 200 MHz to 225 MHz when the input

signal level is ≤ −15.0 dBm (40 mVrms).

4 Record the actual reading in the Performance Test Record (Test 2, Line 3).

5 Disconnect the test setup.
