30. Spurious Response, HP 8593EM

11.Measure the noise level at 5.6 GHz using the following steps:

a.Remove any cable or adapters from the EMC analyzer INPUT 50 ￿.

b.Press 4PRESET5 on the EMC analyzer, then wait for the preset routine to ￿nish. Set the EMC analyzer by pressing the following keys:

4FREQUENCY5 5.6 4GHz5

4SPAN5 ZERO SPAN

4AMPLITUDE5 REF LVL 67 dB￿V

4BW5 IF BW AUTO MAN (MAN) 1 4kHz5

AVG BW AUTO MAN (MAN) 30 4Hz5

More 1 of 2 VID AVG ON OFF (ON) 10 4ENTER5

4SWEEP/TRIG5 SWP TIME AUTO MAN (MAN) 5.0 4sec5

c.Press 4SGL SWP5. Wait until AVG 10 is displayed along the left side of the CRT display.

d.Press 4MKR !5 MARKER ! HIGH on the EMC analyzer and record the marker amplitude reading as the Noise Level at 5.6 GHz in Table 2-47.

12.Press 4PRESET5 on the EMC analyzer, then wait for the preset routine to ￿nish. Set the EMC analyzer by pressing the following keys:

4FREQUENCY5 More 1 of 2 Band Lock 2.75-6.5 BAND 1

4FREQUENCY5 2.8 4GHz5

4SPAN5 10 4MHz5

13.Connect the equipment as shown in Figure 2-42, with the output of the synthesized sweeper connected to the input of the power splitter, and the power splitter outputs connected to the EMC analyzer and the power sensor.

Option 026 only: Use the BNC to SMA adapter with an APC 3.5 (f) to (f) adapter.

14.On the synthesized sweeper, press the preset key, then set the controls as follows:
