System Description
General
The 203M is a versatile charge amplifier covering the frequency range from 5 Hz
to 30,000 Hz. It will accept inputs with sensitivities varying from 1 to 110 mV or
pC/g and provides an output of either 10 mV/g or 100 mV/g with selectable peak
or RMS indication. It also integrates the input signal to provide velocity and
displacement outputs with sensitivities of 10 mV/unit.
