8.Frequency Span Readout Accuracy, HP 8591EM

3.Press INSTRUMENT PRESET on the synthesized sweeper, then set the controls as follows:

CW :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: 74 MHz

POWER LEVEL :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: 05 dBm

4. Set the synthesizer/level generator controls as follows:

FREQUENCY :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: : 66 MHz

AMPLITUDE : :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: : 0 dBm

5.Adjust the EMC analyzer center frequency to center the two signals on the display.

6.On the EMC analyzer, press 4SGL SWP5. Wait for the completion of a new sweep, then press the following keys:

4MKR !5 MARKER ! HIGH

More 1 of 3 More 2 of 3 MARKER 1

More 3 of 3 NEXT PEAK

The two markers should be on the signals near the second and tenth vertical graticule lines (the ￿rst graticule line is the left-most).

7.Record the MKR-1 frequency reading in the performance veri￿cation test record as TR Entry 2. The MKR-1 frequency reading should be within the limits shown.

8. Press 4MKR5, More 1 of 3 , then MARKER ALL OFF on the EMC analyzer.

9.Change the equipment to the next settings listed in Table 2-4.

10.On the EMC analyzer, press 4SGL SWP5. Wait for the completion of a new sweep, then press the following keys:

4MKR !5 MARKER ! HIGH

More 1 of 3 More 2 of 3 MARKER 1

More 3 of 3 NEXT PEAK

11.Record the MKR-1 frequency reading in the performance veri￿cation test record.

12.Repeat steps 8 through 11 for the remaining EMC analyzer span settings through TR Entry 6 (refer to Table 2-4).
