E4407B, and E4408B

29. Other Input-Related Spurious Responses:

This test measures the ability of the analyzer to reject image, multiple,

and out-of-band responses. A synthesized source and the analyzer are

set to the same frequency and the amplitude of the source is set to –10

dBm and –20 dBm. A marker amplitude reference is set on the analyzer

for each source amplitude setting. The source is then tuned to several

different frequencies which should generate image, multiple, and

out-of-band responses. At each source frequency, the source amplitude

is set to the appropriate amplitude and the amplitude of the response, if

any, is measured using the analyzer marker functions.

There are no related adjustment procedures for this performance test.

Procedure

Band 0

1. Zero and calibrate the power meter and power sensor in log mode

(power reads out in dBm), as described in the power meter operation

manual. Enter the power sensor 2 GHz calibration factor into the

power meter.

2. Preset the synthesized sweeper and set the controls as follows:

CW, 2000 MHz

POWER LEVEL, –4 dBm

3. Connect the equipment as shown in Figure 2-44. The analyzer

provides the 10 MHz reference for the synthesized sweeper.
