42. Displayed Average Noise Level, HP 8595EM

Adjust the display line so that it is centered on the average trace noise, ignoring any residual responses (refer to the Residual Responses veri￿cation test for any suspect residuals).

12.Record the display line amplitude setting as TR Entry 2 of the performance veri￿cation test record as the noise level at 1 MHz. The average noise level should be less than the speci￿ed limit.

1 MHz to 2.9 GHz

13. Press the following EMC analyzer keys:

4FREQUENCY5 More 1 of 2 Band Lock 0-2.9 Gz BAND 0

4FREQUENCY5 START FREQ 1 4MHz5

STOP FREQ 2.9 4MHz5

4BW5 IF BW AUTO MAN (MAN) 1 4MHz5

AVG BW AUTO MAN (MAN) 10 4kHz5

4SWEEP/TRIG5 SWEEP CONT SGL (CONT)

14.Press 4FREQUENCY5, then adjust the center frequency, if necessary, to place the LO feedthrough just o￿-screen to the left.

15.Press the following EMC analyzer keys:

4SGL SWP5

4TRACE5 CLEAR WRITE A

More 1 of 4 More 2 of 4 VID AVG ON OFF (ON) 10 4Hz5

Wait until AVG 10 is displayed to the left of the graticule (the analyzer will take ten sweeps, then stop).

16.Press 4MKR !5 MARKER ! HIGH and record the MKR frequency as the Measurement Frequency in the appropriate band under test in Table 2-53.
