60. Tracking Generator Feedthrough, HP 8593EM, HP 8595EM, and HP 8596EM Option 010

11.Press 4FREQUENCY5 and adjust the center frequency until the LO feedthrough peak is on the left-most graticule line, then set the EMC analyzer as follows:

4SPAN5 50 4kHz5

4AMPLITUDE5 REF LVL 57 4dB￿V5

4BW5 IF BW AUTO MAN (MAN) 1 4kHz5 AVG BW AUTO MAN (MAN) 30 4Hz5

4TRACE5 More 1 of 4 More 2 of 4 DETECTOR SMP PK (SMP)

12.Press 4AUX/USER5, Track Gen , SRC PWR ON OFF (ON), then enter 106

4dB￿V5.

13.Press 4SGL SWP5 , then wait for completion of a new sweep. Press 4DISPLAY5,

DSP LINE ON OFF (ON).

14.Adjust the display line so that it is centered on the average trace noise, ignoring any residual responses. Record the display line amplitude setting in Table 2-78 as the noise level at 400 kHz.

15.Repeat steps 13 and 14 for the remaining Tracking Generator Output Frequencies (EMC analyzer center frequency) listed in Table 2-78.

16.In Table 2-78, locate the most positive Noise Level Amplitude. Record this amplitude as TR Entry 1 of the performance veri￿cation test record.
