Model 2100 insulated stimulator
The Model 2100 is an isolated pulse stimulator with integrated optical and transformer isolation, capable of delivering single or two-phase pulses in constant current or voltage mode up to ±100 V or ±10 mA. It operates in free-running, manual or external trigger (TTL) mode, with status LED indicators (TRIG, EVENT, ERROR). It offers exceptional time accuracy thanks to a 10 MHz clock, for timing from 1 µs to over 15 minutes.
Features of the Model 2100 Stimulator
- Free-running, manual or external TTL trigger operation
- LED indicators TRIG (trigger received), EVENT (pulse in progress), ERROR (delivery error)
- Pulse train settings via lever-wheel: delay, train width, pulse duration, interpulse period
- Duration ranges from 1 µs to 999 s (~15 min) with accuracy < 0.02 % and jitter ≤ ±250 ns
- Output modes: current or voltage (switchable), with independent amplitude for pulse and baseline
- Single-phase (±10 mA / ±100 V) or two-phase (±5 mA / ±50 V) pulses as selected
- User-friendly thumbwheel interface and no need for external isolator
