Digital Stimulus Isolator Model 2300

The Model 2300 is a digital stimulus isolator offering complete opto-electrical isolation of computer-generated TTL signals, with amplitude control via front-panel potentiometers and rechargeable battery operation for mains-independent use. It delivers single-phase or two-phase square-wave pulses with very low noise.

Features of the Model 2300 Digital Stimulator

  • TTL interface for three control lines: On/Off, Pulse/Baseline, Polarity
  • Output configurable as constant current or constant voltage, in single-phase or two-phase mode
  • Maximum amplitude up to ±50 V or ±5 mA, set via ten-turn potentiometers
  • Extended bandwidth from DC to 40 kHz, with rise time < 10 µs
  • Very low noise : < 0.003% of full scale (~150 pA RMS in current mode)
  • Autonomous power supply via two internal rechargeable batteries, ≥ 8 h of operation
  • Compact: dimensions ~2.5″ × 6″ × 6.25″
