5. Frequency Readout and Marker Count Accuracy, HP 8593EM, HP 8595EM, and HP 8596EM

Procedure

This performance veri￿cation test consists of two parts:

Part 1: Frequency Readout Accuracy

Part 2: Marker Count Accuracy

Perform \Part 1: Frequency Readout Accuracy" before performing \Part 2: Marker Count Accuracy."

Part 1: Frequency Readout A ccuracy

1.Connect the equipment as shown in Figure 2-5. Remember to connect the 10 MHz REF OUT of the synthesized sweeper to the EXT REF IN of the EMC analyzer.

Option 026 only: Use the 3.5 mm adapter to connect the cable to the EMC analyzer input.

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

CW : : :: : : : : : : : : : : : : : : : : : :: : : : : : : : :: : : : :: : : :: : : : :: : : : : : : : :: : : 1.5 GHz

POWER LEVEL :: : : : : : : : :: : : : : : : : : : : : : : : : : : : : : : : :: :: : : : : : : 010 dBm

3.Press 4PRESET5 on the EMC analyzer, wait for the preset routine to ￿nish, then press 4FREQUENCY5 1.5 4GHz5.

4.On the EMC analyzer, press the following keys to measure the frequency readout accuracy:

4SPAN5 20 4MHz5

4MKR !5 MARKER ! HIGH

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

6.Change to the next EMC analyzer span setting listed in Table 2-2.

7.Repeat steps 4 through 6 for the EMC analyzer 10 MHz and 1 MHz span settings as listed in Table 2-2.

8.Change the synthesized sweeper CW frequency and the EMC analyzer center frequency and span as required by Table 2-2 and repeat steps 4 through 7.
