Multichannel Systems provide high channel count solutions for signal conditioning applications such as anti-aliasing in digital signal processing, separating specific bandwidths of information, enhancing signal-to-noise ratio, low noise pre-amplification and more. Five-slot and 16-slot chassis are available for total channel counts from 1 to 32. All filter/amplifier cards plug-in from the rear panel and are controlled via the front panel keyboard or over the GPIB interface.
