1217-C

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
• Internally Generated: 2.5 Hz to 1.2 MHz, ±5%
• Externally Controlled: DC to 2.4 MHz with 1 V_RMS input, (0.5 V at 1 MHz and lower)

• OUTPUT PULSE CHARACTERISTICS
• Duration: 100 ns to 1 s in 7 decade ranges, ±5% of reading or ±2% of full scale or ±35 ns, whichever is greater
• Rise and Fall Times: Less than 10 ns into 50 or 100 Ω; typically 60 ns + 2 ns/pF external load capacitance into 1 kΩ (40 V)
