: If RSA3015N, RSA3030N, and RSA3045N have not been installed with the RSA3000-BW1
option, then the maximum value of IF BW is 3 MHz.
Remarks:
⚫ Reducing the IF BW of the receiver can undermine the impact of random noises
on the measurement.
⚫ Reducing the IF BW to 1/10 of the original bandwidth can reduce the ground
noise by 10 dB.
