The Datapulse Model lOOA is an economical high performance pulse generator designed for general purpose testing of a variety of electronic equipment. Unique, all solid state circuits reduce complexity and provide versatile performance in a conveniently compact package. Simultaneous positive and negative outputs deliver Z watts into 50 ohms, and pulse rate, width, amplitude, and delay are continuously variable over broad ranges. Front panel controls select either single or double pulse operation, synchronous or asynchronous gating, and either internal, external, or manual single cycle triggering. Two synchronizing trigger outputs are supplied for system application and to provide a reference for pulse delay in the single pulse mode.
