Hello
I have a SMPS and would like to measure ripple and noise from 9Khz to 100Khz using a spectrum analyzer.
So I have a DSA 875 from Rigol that can measure from 9Khz and up.
This is the first time I am using a spectrum analyzer and I have no idea what to do. Should I use a capacitor in line (to block the DC) ? I assume that C and R(50R) will make a HPF so I calculated that C should be at least 2.2uF
I would like the results to be very accurate (uV level).
