Assembly-Level Service Guide 1-61
1
2.8 to 3.0 GHz Sensitivity for Option 030 Only
1 Disconnect the HP 8663A Synthesized Signal Generator from the
Counter (see Figure 1-14), and connect the HP 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).
