17. Image, Multiple, and Out of Rand Responses Test

Procedure

1. Connect equipment as shown in Figure 2-31 with the synthesized

sweeper RF OUTPUT connected to the analyzer input.

2. Press INSTR PRESET on the synthesized sweeper. Key in the

following sweeper settings:

CW FUNCTION

....................................

3000.000 MHz

POWER LEVEL

..........................................

0.0

dBm

3. Press

(2)

on the analyzer. Key in the following analyzer

settings:

[CENTER FREQUENCY)

........................................

GHz

[FREQUENCY

SPAN)

.........................................

100

kHz

4. Press DISPLAY LINE

(ENTER)

and key in -70

dBm.

5. Press MARKER

[PRESEL

PEAK) and wait for PEAKING! message to

disappear from the display. Press MARKER

(j).

6. Adjust the power level of the synthesized sweeper to place the

peak of the signal trace at the top CRT graticule line.

Note

If the maximum output power level of the synthesized sweeper is not

enough to place the signal peak at the top CRT graticule line, then

adjust the spectrum analyzer REFERENCE LEVEL

as.required

place the signal peak at the top CRT graticule line.

7. Press MARKER

Ia].

Using the DATA knob, determine the

amplitude of the spurious response and enter the result in

‘Ihble

2-20.

8. Set the synthesized sweeper to the frequencies in

‘Pable

2-20

corresponding to an analyzer center frequency of 3

GHz.

The

maximum allowable amplitude of the spurious response at the

analyzer center frequency for each setting is shown in the table.
