Chapter 1 Performance Tests

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

1-60 Assembly-Level Service Guide

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

at ≤ −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 Agilent 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.

2 On the Counter, Press Run key.

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 2.7 GHz.

The Counter should read frequencies from 100 MHz to 2.7 GHz

at ≤ −27.0 dBm (20 mVrms).

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