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″
