4. Frequency Readout and Marker Count Accuracy, HP 8591EM and HP 8594EM

Part 2: Marker Count A ccuracy

Perform \Part 1: Frequency Readout Accuracy" before performing this procedure.

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

4FREQUENCY5 1.5 4GHz5

4SPAN5 20 4MHz5

4BW5 IF BW AUTO MAN (MAN) 300 4kHz5

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

More 2 of 3 CNT RES AUTO MAN (MAN) 100 4Hz5

2.Press 4MKR !5 MARKER ! HIGH , then wait for a count to be taken (it may take several seconds).

3.Record the CNTR frequency reading as TR Entry 5 of the performance veri￿cation test record. The reading should be within the limits of 1.4999989 GHz and 1.5000011 GHz.

4.Change the EMC analyzer settings by pressing the following keys:

4SPAN5 1 4MHz5

4MKR5 More 1 of 3 More 2 of 3 CNT RES AUTO MAN (MAN) 10 4Hz5

5.Press 4MKR !5 MARKER ! HIGH , then wait for a count to be taken (it may take several seconds).

6.Record the CNTR frequency reading as TR Entry 6 of the performance veri￿cation test record. The reading should be within the limits of 1.49999989 GHz and 1.50000011 GHz.

7.Set the EMC analyzer by pressing the following keys:

4BW5 IF BW AUTO MAN (MAN) 300 4Hz5

4SPAN5 20 4kHz5

8.Press 4MKR !5 MARKER ! HIGH on the EMC analyzer.

9.Record the MKR frequency reading as TR Entry 7 of the performance veri￿cation test record. The reading should be within the limits of 1.49999989 GHz and 1.50000011 GHz.
