Performance Verification Tests

9. System-Related Sidebands

a. Set the synthesized signal generator controls as follows:

FREQUENCY, 500 MHz

AMPLITUDE, 0dBm (50 Ω Input only)

AMPLITUDE, 6 dBm (75 Ω Input only)

AM Off

FM Off

b. Connect the equipment as shown in Figure 2-9.

c. Press Preset on the analyzer. Press the Factory Preset softkey, if it

is displayed. Set the analyzer by pressing the following keys:

FREQUENCY, 500 MHz

SPAN, 10 MHz

2. Set the analyzer to measure the system-related sideband above the

signal by performing the following steps:

a. Press the following keys:

Peak Search (or Search)

FREQUENCY, Signal Track (On)

SPAN, 200 kHz

BW/Avg, 1kHz

Video BW, 30 Hz (Man)

Allow the analyzer to take two complete sweeps. Then press the

following keys:

FREQUENCY, Signal Track (Off)

CF Step, 130 kHz (Man)

b. Press Single and wait for the completion of the sweep. Press

Peak Search (or Search), then Marker, Delta.

c. Press the following keys:

↑(step-up key)

3. Measure the system-related sideband above the signal by pressing

Single on the analyzer. Wait for the completion of a new sweep, then

press Peak Search (or Search).

4. Record the marker delta amplitude as Test Record entry 1 of the

performance verification test record.

5. Set the analyzer to measure the system-related sideband below the

signal by pressing the following keys:

FREQUENCY

↓ (step-down key)

6. Measure the system-related sideband below the signal by pressing
