24. Other Input Related Spurious Responses, HP 8591EM

Procedure

1.Zero and calibrate the measuring receiver and power sensor in log mode (power reads out in dBm), as described in the measuring receiver operation manual. Enter the power sensor's 542.8 MHz Cal Factor into the measuring receiver.

2.Press INSTRUMENT PRESET on the synthesized sweeper and set the controls as follows:

CW :: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: : 542.8 MHz

POWER LEVEL :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: : 020 dBm

3.Connect the equipment as shown in Figure 2-33. Connect the output of the synthesized sweeper to the power sensor.

4.Adjust the synthesized sweeper power level for a 020 dBm 60.1 dB reading on the measuring receiver.

5.On the synthesized sweeper, press SAVE 1.

6.Enter the power sensor's Cal Factor for 1142.8 MHz into the measuring receiver.

7.Set the CW frequency on the synthesized sweeper to 1142.8 MHz.

8.Adjust the synthesized sweeper power level for a 020 dBm 60.1 dB reading on the measuring receiver.

9.On the synthesized sweeper, press SAVE 2.

10.Enter the power sensor's Cal Factor for 500 MHz into the measuring receiver.

11.Set the CW frequency on the synthesized sweeper to 500 MHz.

12.Adjust the synthesized sweeper power level for a 020 dBm 60.1 dB reading on the measuring receiver.

13.Connect the synthesized sweeper to the RF INPUT of the EMC analyzer as shown in Figure 2-33.

14.On the EMC analyzer, press 4PRESET5, then wait for the preset routine to ￿nish. Set the EMC analyzer by pressing the following keys:

4FREQUENCY5 500 4MHz5

4SPAN5 10 4MHz5

4AMPLITUDE5 97 4dB￿V5
