The 73A-270 Arbitrary Pulse/Pattern Generator Module is a printed circuit board assembly for use in a card cage conforming to the VXIbus Specification, such as the 73A-021 used in the CDS 73A IAC System. The module provides two completely independent output channels with a common VXIbux backplane interface. Each channel can be individually programmed to generate an arbitrary string of active and inactive TTL or bipolar analog pulse or pattern outputs.
