• 100 Hz (-3dB at 100 Hz, < -18dB at 50Hz). Useful for attenuating the
signal at 50/60 Hz. Gives a better signal-to-noise ratio for measuring
harmonics
in mains or measuring weak signals at high frequencies without
the fundamental overloading the dynamic range.
Response with the different filters, slightly different if a limit has been selected or not.
