Pulse Instruments PI-451

Manuals – Specifications – Links – Pictures

The Pulse Instruments PI-451 is a MOS/CCD driver plug-in for the TM500 system.

The PI-451 is described as a "MOS/CCD Driver", the PI-451A as a "Programmable Pulse Driver."

A TTL-level input pulse controls an output with programmable high and low voltages and transition times.

Key Specifications

Output low level	+24 V to –25 V open circuit, or +12 V to –12.5 V into 50 Ω
Output swing	1 V min. to 30±3 V max. open circuit, or 0.5 V min. to 15±1.5 V max. into 50 Ω
Output level control	manual, voltage programming (1:1, offset ≤80 mV @ ×1 transition time), or (Opt.002) digital
Transition time	2 ns/V to 2 μs/V @ 25 V and 100 pF load, continuously variable in 3 ranges, independent leading and trailing edge controls
Trigger input	TTL level, 2−5 V into 50 Ω
Trigger output	TTL level, 3 V into 50 Ω, delayed 100 ns from input
Delay	15 ns or ≤100 ns to ≥100 μs from trigger output, 3 decade ranges + 10:1 variable
Pulse width	same as input, or ≤100 ns to ≥100 μs, 3 decade ranges + 10:1 variable
