19.On the spectrum analyzer, press
by entering the frequency value for the corresponding band listed below:
for an 11974A: 35.226200 GHz (n
for an 11974Q: 41.169650 GHz (n
for an 11974U: 49.919650 GHz (n
for an 11974V: 58.279767 GHz (n
20.Record the above frequency in
#1. Press
PEAK SEARCH
The absolute value of the delta marker amplitude is the multiple response rejection.
NOTE
If the signal is buried in the noise floor, reduce the video bandwidth to 100 Hz
to help identify the signal. At some frequencies, however, instrument
performance is so good that an image response may not be visible.
21.Record the multiple response rejection in
Rejection #1.
22.On the spectrum analyzer, press
response by entering the frequency value for the corresponding band listed below:
for an 11974A: 36.083269 GHz (n
for an 11974Q: 41.973150 GHz (n
for an 11974U: 50.723150 GHz (n
for an 11974V: 59.029700 GHz (n
23.Record the above frequency in
#2. Press
PEAK SEARCH
The absolute value of the delta marker amplitude is the multiple response rejection.
24.Record the multiple response rejection in
Rejection #2.
25.Set the synthesized sweeper for a CW signal at the frequency listed below for the
corresponding band:
for an 11974A: 33.25 GHz
for an 11974Q: 41.50 GHz
for an 11974U: 50.00 GHz
for an 11974V: 62.50 GHz
