Overview
FAST IMPULSE GENERATOR
Optical trigger versions compatible with Highland optical transmitter products:
V880 System Timing Module
V720 Electrical/Optical Converter VME Module
J720 Electrical/Optical Converter
J724 Electrical/Optical Converter
V951-6 Optical-Output VME Delay Generator
Typical waveform driving 50-ohm load.
Features
- Generates 65 volt, 350 ps positive pulses.
- Compact, rugged extruded package allows the pulse generator to be located wherever most convenient, including embedded applications.
- Accepts trigger inputs from the Highland electrical signal generators or compatible sources. Optionally equipped units can also accept optical triggers from Highand e/o converters or compatible sources.
- Adjustable logic-level inputs are compatible with TTL, LVTTL, ECL, NIM and most other common logic levels.
- Optionally equipped optical trigger version T250-1 uses commonly available 62/125-m, 850-nm, ST-connectorized multimode fiber with user-adjustable optical threshold level. The T250-3 & T250-5 versions are suited for use with singlemode or multimode fiber at 1310 and 1550 nm.
- On-board O/E converter provides fast analog electrical output for monitoring fiberoptic link quality.
- Timing jitter typically below 3 ps RMS.
- Ideal accessory for Highland Model P400 Digital Delay/Pulse Generator
