5.2.2 Analog Modulation Analysis
When AM or FM modulation type is selected, analog modulation analysis is carried out.
5.2.2.1 IFBW
After entering into the mode AM or FM modulation analysis, set the intermediate frequency bandwidth
(IFBW).
Press Meas Setup, you can set the "IFBW" again.
It specifies the IFBW of the signal to be analyzed. The measurement accuracy will be impacted if this
value isn't set precisely. The IFBW should be as narrow as possible to improve the S/N ratio.
For AM modulation analysis, the IFBW should be larger than twice the modulation frequency. For FM
modulation analysis, the IFBW should be larger than twice the sum of the deviation frequency and the
modulation frequency.

5.2.2.2 EqLPF
After entering into the mode AM modulation analysis or FM modulation analysis, set the equivalent low
pass filter (EqLFP).
Press Meas Setup, you can set the "EqLFP" again.
It specifies the EqLPF bandwidth of the signal to be analyzed. The measurement accuracy will be
impacted if this value isn't set precisely. The EqLPF is an additional low pass filter. It can conveniently
