90PF Slot Card

Dual Channel Programmable Introduction Filter/Amplifier Card

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 band-reject (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. Features • 0.1 Hz to 300 kHz Tuning Range • Selectable single-ended or differential input • Gain/phase matched channels • LED clipping indicators • Memory storage for up to 9 set-ups/slot card • <-100 dB signal-to-noise ratio to 100 kHz BW • Programmable gain, 60 dB pre and 20 dB post Applications • Anti-Aliasing • Sound Measurement • Noise Testing • Audio Communications • Medical Research • Industrial Process Control • Seismic Analysis • Vibration Analysis
