22.Calculate the 3 dB bandwidth at this frequency using the following equation:
High DAC number Low DAC number
--------------------------------------------------------------------------------------------------------- -
where n represents the harmonic number listed below:
11974A: 8
11974Q: 10
11974U: 10
11974V: 14
NOTE
The above equation applies only when the spectrum analyzer is an 8566B.
When using an 8563A or 71000C spectrum analyzer, use the following
equation:
High DAC number Low DAC number
--------------------------------------------------------------------------------------------------------- -
23.Set the synthesized sweeper for a CW signal at the frequency listed below:
for an 11974A: 33.25 GHz
for an 11974Q: 41.5 GHz
for an 11974U: 50 GHz
for an 11974V: 62.5 GHz
24.Set the center frequency of the spectrum analyzer by pressing
then entering the corresponding value for the band listed below:
for an 11974A: 33.25 GHz
for an 11974Q: 41.5 GHz
for an 11974U: 50 GHz
for an 11974V: 62.5 GHz
25.Repeat
step 15
through
Table 4-11
on page 146.
26.Set the synthesized sweeper for a CW signal at the frequency listed below:
for an 11974A: 40 GHz
for an 11974Q: 50 GHz
for an 11974U: 60 GHz
for an 11974V: 75 GHz
