9. Frequency Span Readout Accuracy, HP 8593EM, HP 8594EM, HP 8595EM, and HP 8596EM

Part 1: 1800 MHz Frequency Span Readout A ccuracy

1.Connect the equipment as shown in Figure 2-10 (Figure 2-11 for HP 8594EM). Note that the power splitter is used as a combiner.

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

4FREQUENCY5 900 4MHz5

4SPAN5 1800 4MHz5

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

CW :: :: :: : : : : : :: : : : :: : : :: : : : :: :: :: : : :: : : : :: : : : : : : : :: : : : : : : : : 1700 MHz

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

4. On the signal generator, set the controls as follows:

FREQUENCY (LOCKED MODE) :: : : : : : : : : : : : : : : : : : : : : : : : : : : 200 MHz

CW OUTPUT : : :: : : : :: :: :: : : : :: : : : : : : : :: : : : : : : : :: : : : : : : : : : : : : : : 0 dBm

5.Adjust the EMC analyzer center frequency, if necessary, to place the lower frequency on the second vertical graticule line (one division from the left-most graticule line).

6.On the EMC analyzer, press 4SGL SWP5 .

Wait for the completion of a new sweep, then press:

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.Press More 1 of 3 More 2 of 3 MARKER 1 More 3 of 3 , then continue pressing NEXT PK RIGHT until the marker 1 is on the right-most signal.

8.Record the MKR 1 frequency reading as TR Entry 1 of the performance veri￿cation test record.

The MKR reading should be within the 1446 MHz and 1554 MHz.
