Chapter 1 Performance Tests

Test 4: Option 015/030/050/124 Channel 2 Frequency Sensitivity

Assembly-Level Service Guide 1-61

2.8 to 3.0 GHz Sensitivity for Option 030 Only

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

(see Figure 1-14), 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 3.0 GHz.

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

4 Sweep the frequencies from 3.0 GHz to 2.8 GHz.

The Counter should read frequencies from 3.0 to 2.8 GHz at ≤ −21.0 dBm.

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

6 Disconnect the test setup.

200 MHz to 5.0 GHz Sensitivity for Option 050 only

1 Connect the 8340B Sweep Oscillator to Channel 2 of the counter.

2 Change the settings of the Sweep Oscillator to 5.0 GHz, −30 dBm.

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

of approximately 5.0 GHz.

The Counter should display 5.0 GHz at ≤ −23 dBm.

NOTE Use a power meter and sensor to ensure the accuracy of the power being input.

4 Sweep the frequencies from 200 MHz to 5.0 GHz.

The Counter should read frequencies from 200 MHz to 5.0 GHz at ≤ −23 dBm.

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