Chapter 1 Performance Tests

Test 5: Option 030/050/124 Channel 3 Frequency Sensitivity (Agilent

53131A/132A Only)

1-32 Assembly-Level Service Guide

3 Increase the power level in 5 dB steps until the Counter displays a stable reading

of approximately 2.5 GHz.

The Counter should display 2.5 GHz at ≤ −27.0 dBm (10 mVrms).

4 Sweep the frequencies from 2.5 GHz to 200 MHz.

The Counter should read frequencies from 2.5 GHz to 200 MHz at

≤ −27.0 dBm (10 mVrms).

5 Record the actual reading in the Performance Test Record (Test 5, Line 1).

2.7 to 3.0 GHz Sensitivity for Option 030 only

1 Disconnect the Agilent 8663A Synthesized Signal Generator from the Counter

(see Figure 1-9), and connect the Agilent 8340B Sweep Oscillator to Channel 3 of

the Counter.

2 Change the settings of the Sweep Oscillator to 3.0 GHz, −40 dBm.

3 Increase the power level in 1 dB steps until the Counter displays a stable reading

of approximately 3.0 GHz.

The Counter should display 3.0 GHz at ≤ −21.0 dBm.

4 Sweep the frequencies from 3.0 GHz to 2.7 GHz.

The Counter should read frequencies from 3.0 to 2.7 GHz at ≤ −21.0 dBm.

5 Record the actual reading in the Performance Test Record (Test 5, Line 2).

6 Disconnect the test setup.
