Programmable gain amplifiers support overall gains from 0 to ±100.00x in steps of 0.01x. Full-scale input range is settable from 1Vpp to 20Vpp and the outputs are fully buffered with an output drive to 22Vpp. The standard filters are linear phase, finite impulse response (FIR) digital filters from 3 to 128 taps in dual channel mode, or up to 256 taps in single channel mode giving a passband to stopband transition width as small as 0.4KHz for a 10KHz low-pass filter. Filter settings are easily stored and recalled from any of five memory locations.
A liquid crystal display shows the filter settings or bar-graph type VU-level meters that display the I/O signal dynamics. Filter parameters may be adjusted with the knob or by sending simple ASCII commands through the built-in RS-232 serial port. An optional PC can control an unlimited number of daisy-chained Versa-Filter systems. For more details, see the VF Users Guide below.

General Description of Versa-Filter System
The Versa-Filter System is a versatile 2-channel electronic filter and signal conditioning system built around the Versa-Filter Module; a DSP based filter module with analog I/O. The System features programmable gain amplifiers, fully tunable low-pass, high-pass, band-pass, band-stop, notch and inverse-notch filters that operate from DC to 20KHz with a 1Hz tuning resolution. The Versa-Filters are also user programmable with custom filter coefficients to meet special filtering needs.
