Two channel Stimulator/Pulse generator for neurophysiology and behavioral studies

Two channel TTL pulse stimulator
Two channel TTL pulse stimulator


In contrast with a standard lab stimulator Invilog Stimulator/Pulse generator provides automatic scheduled stimulation during weeks or months – for example, it may switch complex stimulation patterns on and off every 12 hours. It may also finish each cycle of daily stimulation with a specific pulse parameter (option for use with Invilog wireless stimulators with microcontroller).

Pulse length, frequency of stimulation, burst length, burst period, train length, interval between trains (experiments) can be set for each experiment. Invilog stimulator also permits one to control  Invilog Wireless Stimulators.

Small size (17 x 12 x 4 cm) and touch screen interface makes Invilog stimulator suitable for any laboratory space. You may also preprogram each terminal box for one cycle stimulation (e.g. 8 hours) and use it independently from the main unit for example in the animal center or an area without electricity supply. In this case power to the terminal boxes is taken from the conventional power banks.

Key features

  • Two independent output channels produce TTL pulses with a specified length, frequency and patterns
  • Pulse generation for each channel can be initiated/interrupted:
    • by predefined schedule
    • from a touch screen
    • by external TTL pulses from trigger input
  • The scheduled stimulation delivers patterns of pulses during specific time and then automatically stops for predefined time, so that the next stimulation will start automatically (e.g. during weekend)
