Chapter 1 Performance Tests

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

53131A/132A Only)

3Increase 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).

4Sweep 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).

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

2.7 to 3.0 GHz Sensitivity for Option 030 only

1Disconnect the HP 8663A Synthesized Signal Generator from the Counter (see Figure 1-9), and connect the HP 8340B Sweep Oscillator to Channel 3 of the Counter.

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

3Increase 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.

4Sweep 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.

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

6Disconnect the test setup.
