The Manual TTL Pulser is a hand-held device that, at the press of a button, sends digital signals (TTL pulses) to label stimulus, behavior or other events during a recording (fiber photometry, microscopy, optogenetics, electrophysiology, etc.)

Manual TTLPulser has two modes:

  • Pulse - short TTL pulse outputs every time the button is selected
  • Gated - continuous 0 or 1 outputs depending on the position of the switch


The Manual TTL pulser pairs readily with any of Doric Lense's console: NC500, FPC, BBC300, OTPG and any of Light Sources Drivers. It will also work with any DAQ or drivers that can support 5V digital input signals.
