90PF Slot Card Dual Channel Programmable Filter/Amplifier Card
Description Each 90PF slot card provides channels precision, noise distortion (-100 typical) programmable filters with post adjustable gain. Filter modules programmable from utilizing 11-bit tuning ranges. When assembled with high-pass filter channel low-pass filter channel (2), 90PF slot cards configured operate low-pass, high-pass, band-pass, bandreject (notch) filter. Customers select combination available filter modules slot card meet their application specific signal conditioning needs. Front panel mounted BNC' provide easy access connection signal input output. Other features include differential single-ended input, DC-coupled input, single ended output, clipping indicators fine adjustment offset. Operating 90PF filter BYPASS mode allows design engineer each channel precision instrumentation grade programmable amplifier. Features Tuning Range Selectable single-ended differential input Gain/phase matched channels clipping indicators Memory storage set-ups/slot card <-100 signal-to-noise ratio Programmable gain, post Applications Anti-Aliasing Sound Measurement Noise Testing Audio Communications Medical Research Industrial Process Control Seismic Analysis Vibration Analysis
