90PF Slot Card
Dual Channel Programmable
Filter/Amplifier Card
Introduction
Description
Each 90PF slot card provides two channels of
precision, low noise and distortion (-100 dB typical)
programmable filters with up to 60 dB of pre and 20
dB of post adjustable gain.
Filter modules are programmable from 0.1 Hz to
300 kHz utilizing 4, 11-bit tuning ranges. When
assembled with a high-pass filter in channel one
(1) and a low-pass filter in channel two (2), 90PF
slot cards can be configured on the fly to operate
as a low-pass, high-pass, band-pass, or bandreject (notch) filter. Customers can select any
combination of two available filter modules per slot
card to meet their application specific signal
conditioning needs.
Front panel mounted BNC’s provide easy access
for connection of signal input and output. Other
features include differential or single-ended input,
AC or DC-coupled input, single ended output, LED
clipping indicators and fine adjustment of DC
offset. Operating the 90PF in filter BYPASS mode
allows the design engineer to use each channel as
a precision instrumentation grade programmable
amplifier.
