eLockIn 204

The extraordionary filtering quality of this lock-in amplifier
resulting in more than 130 dB Dynamic Reserve
is achieved by a well chosen oversampling rate of 40 MHz and
a fully digital design with 96 bit wide digital filters.

This warranties best results in all input ranges and allows for
the display of 7 digits of the 32 bit wide floating point results
on all demodulation output channels.

The dedicated analogue input stage
is designed for lowest noise,
a small input capacitance and
optimized for 1 MHz bandwidth.
