Hi everyone,
I am planning to buy a DSO (Siglent 1000X most likely). I am curious how good is the FFT function of these scopes? are they able to show the harmonics and their relative powers (not accurate but approximate) of a RF device whose frequencies (e.g. 144 MHz) are higher than the Analog bandwidth of the scope itself (e.g. -3db bandwidth of 50 or 100 MHz)?
How good is the resolution power and relative power measurement capability of these scopes in the lower RF band (< 30 MHz) for a DSO with 100Mhz analog bandwidth?
Many thanks in advance.
