The Model 2100 Isolated Pulse Stimulator is ideal for a wide variety of physiological stimulation protocols, including, but not limited to: behavioral feedback, LTP/LTD, lesion making, electrode marking, ultrafast timing applications, orthodromic/antidromic stimulation, and kindling.

With a built-in stimulus isolator circuit, there is no need for an external SIU to convert voltage pulses into constant current pulses. The Model 2100 is can operated continuously (free-running mode), be manually triggered, or be externally triggered via a TTL pulse from a computer or a footswitch.

Status and error lights indicate functionality. Easy-to-set leverwheel switches determine durations and intervals.

  • Timing range from 1 µS to over 15 minutes
  • Highly accurate! Better than 0.02%
  • No need for expensive external SIU as output is optically isolated!
  • Mono or Biphasic Output Capability
  • Status Indicators

The Model 2100 Isolated Pulse Stimulator is A-M Systems best-selling instrument, and can serve as a workhorse stimulator in your laboratory.

  • Wide timing range: 1 µs to 999.9 seconds
  • Excellent timing accuracy: better than 0.02%, with less than 250 ns jitter (less than 2.5 µs jitter on 100 second range)
  • Optically-isolated, short-circuit protected output
  • Mono- or bi-phasic pulse outputs
  • Calibrated current or voltage mode output up to:
    • monophasic: 0 to +10 mA or 0 to -10 mA; 0 to +100 V or 0 to -100 V
    • biphasic: ±5 mA or ±50 V
  • Status indicators: operational state and setup/control errors
  • Trigger outputs for both individual pulses and the entire burst train
  • Optical isolator-coupled output control
  • No battery required: isolation transformer power supply

Pulse Train Parameters

The desired pulse train parameters are determined by setting four times using the banks of leverwheels and rotary knobs on the front panel:

  • The delay time (time between trigger and the first pulse);
  • train burst width time;
  • individual pulse duration;
  • interpulse period (the duration of a single pulse on/off cycle).

If the period is set to be shorter than the pulse duration, a timing overlap error LED indicator warns the user of this condition.

For ease of use, the delay may be set to "none," so that no extra delay occurs between trigger and pulse output. The burst width may be set to "single," so that only a single pulse is output for a single triggering event. This has the additional effect of suppressing the post-pulse delay associated with the inter-pulse period, thus allowing the stimulator to become immediately retriggerable, instead of waiting until the end of the period.

The pulse duration may be set to "square", automatically setting the duration to one half of the period.

The times are easily and rapidly set with leverwheel switches, which are much more convenient than thumbwheel switches. The timing accuracy is dependent only on a 10 MHz internal crystal clock which has an absolute accuracy of better than 0.02% and timer-start jitter of ±250 ns (±2.5 µs in the 100 second range).

Amplitude

The full-scale amplitude accuracy is 1%, with a voltage-mode output impedance of less than 60 Ohms, and a current-mode output impedance of at least 1 MegOhms. The output pulses may be monophasic (selectable polarity) or biphasic, in which a positive pulse is immediately followed by a negative pulse. The baseline amplitude is independently adjustable up to ±10% of the pulse amplitude range.
