3-channel plug-in filter/amplifier carrier card

1Amplifier carrier carddescription

The FLX-303 analog filter/amplifier carrier card for FLX-3007 chassis is an ideal choice for applications that require signal conditioning with Bessel or Butterworth filters. You can choose high pass, low-pass, or band-pass filtering. The cut-off frequency range defined by the customer is 1Hz to 1MHz (low-pass and band-pass) and 1Hz to 600kHz (high pass), and offers a 6dB to 96dB/octave roll off option for any filter type. FLX-303 accepts input signals between ± 10V. FLX-303 has low noise of 10 μ V (referred to as input) and a signal-to-noise ratio>120dB.

The differential input amplifier and output amplifier in each channel allow programmable resistor gains ranging from 1 to 100, with a total gain of up to 10000 if needed. The available peak gain is determined by the cutoff frequency and bandwidth of the selected filter.

The filter and amplifier characteristics are defined by the customer in each channel and can be changed later by replacing the filter/amplifier plugin 3F filter/amplifier module for each channel.

FLX-303 is one of the many plug-in cards available for FLX-3007, a 7-slot chassis system.
