Procedure

1. Connect the equipment as shown in Figure 4-2. Remember to connect the 10 MHz REF

OUT of the analyzer to the 10 MHz REF IN of the synthesized sweeper.

2. Perform the following steps to set up the equipment:

a. Press INSTRUMENT PRESET on the synthesized sweeper, then set the controls to:

CW, 1.490, GHz

POWER LEVEL, 10, – dBm

b. Pre ss System, Power On/Preset, Preset Type (Factory), Preset on the analyzer, then

wait for the preset routine to finish. Set the analyzer by pressing the following keys:

Frequency, 1.490, GHz

SPAN, 10, MHz

BW/Avg, Res BW, 100, kHz

Video BW, 30, kHz

CAUTION Use only 75 Ω cables, connectors, or adapters on analyzers with 75 Ω inputs,

or damage to connectors will occur.

3. Press Peak Search on the analyzer to measure the frequency readout accuracy. Record

this in the Marker Frequency Readout column in Table4-2 on page 141.

4. Press Span, 100, kHz, BW/Avg, Res BW, 1, kHz, Video BW, 1, kHz.

5. Press Peak Search on the analyzer to measure the frequency readout accuracy. Record

this in the Marker Frequency Readout column in Table4-2 on page 141.

NOTE The Frequency Readout Accuracy in now complete. Continue with the Marker

Count Accuracy functional check.
