The capacitive load at the input of the amplifier has an impact on the resolution of the measurement. The rms noise contribution for particle spectroscopy as a function of the capacitive input load is shown on the left.
With an input capacitance of 1 nF, the noise contribution of the CxL-100 is about 1e4 electrons. Depending on the acceptable noise contribution of the amplifier a maximum input capacitive load is to be specified, from which the acceptable detector cable length is derived for the measurement setup.
