Chapter 1 Performance Tests

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

3Increase 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).

4Sweep the frequencies from 100 MHz to 1.5 GHz.

The Counter should read frequencies from 100 MHz to 1.5 GHz at ≤ −27.0dBm (20 mVrms).

5Record the actual reading in the Performance Test Record (Test 4, Line 1).

100 MHz to 2.7 GHz Sensitivity for Option 030 Only

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

500 MHz, −60 dBm sine wave, and connect the signal to Channel 3 of the Counter as shown in Figure 1-14.

2On the Counter, Press Run key.

3Increase 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).

4Sweep the frequencies from 100 MHz to 2.7 GHz.

The Counter should read frequencies from 100 MHz to 2.7 GHz at ≤ −27.0 dBm (20 mVrms).

5Record the actual reading in the Performance Test Record (Test 4, Line 2).
