12. Sweep Time Accuracy, HP 8590 EM-Series

Procedure

1.Set the signal generator to output a 500 MHz, 010 dBm, CW signal. Set the AM and FM controls to o￿.

2.Set the synthesizer/function generator to output a 500 Hz, +5 dBm triangle waveform signal.

3.Connect the equipment as shown in Figure 2-15.

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

4FREQUENCY5 500 4MHz5

4SPAN5 10 4MHz5

4MKR !5 MKR ! HIGH

4MKR5 More 1 of 3 MK TRACK ON OFF (ON)

4SPAN5 50 4kHz5

5.Wait for the AUTO ZOOM routine to ￿nish, then press the following EMC analyzer keys:

4SPAN5 ZERO SPAN

4BW5 3 4MHz5

4SWEEP5 20 4ms5

4AMPLITUDE5 SCALE LOG LIN (LIN)

6.Adjust signal amplitude for a midscreen display.

7.Set the signal generator AM switch to the AC position.

8. On the EMC analyzer, press 4SWEEP/TRIG5 Trigger VIDEO , then adjust the video trigger so that the EMC analyzer is sweeping.

9.On the EMC analyzer, press 4SGL SWP5. After the completion of the sweep,

press 4MKR !5 MKR ! HIGH . If necessary, press NEXT PK LEFT until the marker is on the left-most signal. This is the \marked signal."

10.Press More 1 of 3 More 2 of 3 MARKER DELTA More 3 of 3 and then

press NEXT PK RIGHT eight times so the marker delta is on the eighth signal peak from the \marked signal."

Record the marker 1 reading as TR Entry 1 in the performance veri￿cation test record.
