12. Other Input Related Spurious Responses
A synthesized source and the spectrum analyzer are set to the same frequency and the amplitude of the source is set to -10 dBm. A marker-amplitude reference is set on the analyzer. The source is then tuned to several different frequencies which should generate image responses. At each source frequency, the source amplitude is set to -10 dBm and the amplitude of the response, if any, is measured using the spectrum analyzer marker function.
The marker-amplitude difference is then compared to the specification.
There are no related adjustment procedures for this performance test.

Procedure
1. Zero and calibrate the measuring receiver and the power sensor in log mode so that power is read out in dBm. Enter the power sensor’s 542.8 MHz Cal Factor into the measuring receiver.
Option 001 only:
Use 75 61 power sensor.
2. Press INSTRUMENT PRESET on the synthesized sweeper and set the controls as follows:

3. Connect the equipment as shown in Figure l-17. Connect the output of the synthesizer to the power sensor using adapters.
Option 001 only:
Use the minimum loss adapter and 75 D adapter to connect to the 75 Q power sensor.
4. Adjust the synthesized sweeper power level for a -10 dBm *O. 1 dB reading on the measuring receiver.
5. On the synthesized sweeper, press SAVE 1.
6. Enter the power sensor’s Cal Factor for 1142.8 MHz into the measuring receiver.
7. Set the CW frequency on the synthesized sweeper to 1142.8 MHz.

8.
Adjust the synthesized sweeper power level for a - 10 dBm fO.1 dB reading on the measuring receiver.
9.
On the synthesized sweeper, press SAVE 2.
10.
Enter the power sensor’s Cal Factor for 500 MHz into the measuring receiver.
11.
Set the CW frequency on the synthesized sweeper to 500 MHz.
12.
Adjust the synthesized sweeper power level for a - 10 dBm fO.1 dB reading on the measuring receiver.
13.
Connect the synthesized sweeper to the RF INPUT of the spectrum analyzer using the appropriate cable and adapters.
Option
001
only:
Use the minimum loss adapter and 75 Q adapter as shown in Figure 1-17.

For each of the frequencies listed in ‘Ruble 1-16, do the following: a. Set the synthesized sweeper to the listed CW frequency by pressing RECALL 1 for a CW frequency of 542.8 MHz or RECALL 2 for a CW frequency of 1148.8 MHz.
b.
Press [SGL) and wait for the completion of a new sweep.
c. On the spectrum analyzer, press
(

)
and record the marker-delta amplitude reading in ‘Iable 1-16 as the Actual MKR AAmplitude.
The Actual MKR A Amplitude should be less than the Maximum MKR A Amplitude listed in the table below.
The Maximum MKR A Amplitude is 10 dB more positive than the specification. This is due to the 10 dB change in reference level made in step 15.
