This module is an ideal component for building boxcar averager systems. It includes a wide bandwidth variable gain AC/DC coupled input amplifier with continuous input offset adjustment and a high speed sampling gate with variable width and delay controls. It operates in normal or two baseline sampling modes and features a switch-selected choice of how many samples are included in the averaging process. Separate outputs for the average and last sample taken are also provided. A gate monitor supplies a synchronized gate output pulse for application to an oscilloscope trigger or for referencing associated processing electronics. Trigger input is ECL or TTL or can be derived from the moduleÕs own adjustable trigger generator.
