The General Radio 1217-C Unit Pulse Generator was introduced in Catalog S (1965) and remained available through Catalog 1973.
Type 1217-C is a general-purpose unit type pulse generator, an improved version of Type 1217-B with increased pulse repetition frequency and faster transition times to less than 10 ns.
The 1217-C features a 1.2 MHz PRF internally which doubles to 2.4 MHz with external drive. Other features are front-panel outputs for positive- and negative-going pulses with variable amplitude control.
Pulse duration is continuously variable from 0.1 μs to 1 s in seven ranges. Front panel synchronizing outputs are available for triggering external devices.
The 1217-P2 Pulse Trigger accessory was available for single pulse triggering.
Recommended power supplies are Types 1201-C and 1203-B.
Specifications
- PULSE REPETITION RATE
