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 high level +25 V to –24 V open circuit, or +12.5 V to –12 V into 50 Ω
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
Max. frequency 10 MHz @ 20 V, 20 pF down to 4 MHz @ 25 V, 300 pF
Options Opt. 002 – digitally programmable output voltage levels (12 bit parallel TTL), plus additional TTL clock input and a high level output on the rear interface

Rear interface

  • 3A / 4A – mainframe +11.5 V common return = signal ground
  • 21A – Output low level (connected to green or blue front panel banana jack)
  • 22A – Output high level (connected to red front panel banana jack)
  • 24A (23A GND) – Pulse output (parallel to front panel output unless disconnected via internal switch)
  • 27A (26A GND) – Rear trigger input
  • 25A – /PS Plugin select, must be 0 to load data
  • 28A – /MS Mainframe select, must be 0 to load data
