3 Increase the power level in 1 dB steps until the Counter reads

500 MHz.

The Counter should display 500 MHz at

≤ −

27.0 dBm (20 mVrms).

4 Sweep the frequencies from 100 MHz to 1.5 GHz.

The Counter should read frequencies from 100 MHz to 1.5 GHz

≤ −

27.0dBm (20 mVrms).

5 Record the actual reading in the Performance Test Record

(Test 4, Line 1).

100 MHz to 2.7 GHz Sensitivity for Option 030 Only

1 Set the HP 8663B Synthesized Signal Generator to output a

60 dBm sine wave, and connect the signal to Channel 3

of the Counter as shown in Figure 1-14.

2 On the Counter, Press Run key.

3 Increase the power level in 1 dB steps until the Counter reads
