36.Record the multiple response rejection in Table 4-9 on page 144 as Multiple Response

Rejection #4.

37.On the spectrum analyzer, press

CENTER FREQUENCY and tune to the next multiple

response by entering the frequency value for the corresponding band listed below:

for an 11974A: Response not in band. Skip to step 40.

for an 11974Q: Response not in band. Skip to step 40.

for an 11974U: Response not in band. Skip to step 40.

for an 11974V: 72.863100 GHz (n

′

= 12+)

38.Record the above frequency in Table 4-9 on page 144 as Multiple Response Frequency

#5. Press

PEAK SEARCH to place the delta marker at the top of the multiple response.

The absolute value of the delta marker amplitude is the multiple response rejection.

39.Record the multiple response rejection in Table 4-9 on page 144 as Multiple Response

Rejection #5.

40.On the spectrum analyzer, press

CENTER FREQUENCY and tune to the next multiple

response by entering the frequency value for the corresponding mixer listed below:

for an 11974A: Response not in band. Skip to step 43.

for an 11974Q: Response not in band. Skip to step 43.

for an 11974U: Response not in band. Skip to step 43.

for an 11974V: 73.613033 GHz (n

′

= 12−)

41.Record the above frequency in Table 4-9 on page 144 as Multiple Response Frequency

#6. Press

PEAK SEARCH to place the delta marker at the top of the multiple response.

The absolute value of the delta marker amplitude is the multiple response rejection.

42.Record the multiple response rejection in Table 4-9 on page 144 as Multiple Response

Rejection #6.

43.Set the synthesized sweeper for a CW signal at the frequency listed below for the

corresponding band:

for an 11974A: 40.00 GHz

for an 11974Q: 50.00 GHz

for an 11974U: 60.00 GHz

for an 11974V: 75.00 GHz
