Deliver series of pulse trains using eight programmable channels, and
scale and convert voltage pulses to constant current with an optional SIU.

A-M Systems Model 3800

Wide Timing Range

1 µs to 250 Hours

Minimum Pulse Interval

As short as 3 µs


Better than 0.02%

MultiStim: Programmable 8-Channel Stimulus Generator Model 3800

Each of the 8 Completely Independent Channels Can Deliver

  • Pulse durations as short as 1 µs over a 15 minute timing interval
  • Up to 1 µs with a 250-hour timing interval

In addition to monophasic and biphasic pulse trains, the Model 3800 also delivers traditional protocols such as Paired Pulses and Stepped Pulses. Each channel also has a SUM output, whereby the signals of other channels can be summed together for complicated waveform protocols.

Full Triggering Options Include

  • 8 channel specific TTL BNC connectors
  • 3 generic TTL BNC connectors that any combination of channels can be linked to
  • interchannel triggering

There are 3 gate TTL bnc connectors that can be linked to any channel as well. Pulse or Train TTL sync pulses are provided.

By using one channel to trigger another channel, you can combine the timing ranges, resulting in microsecond pulses occurring every 250 hours (if you needed such a schedule!).

Stimulus program sets can be stored on-board the instrument as well as online. MATLAB® and LabVIEW SDK and drivers are also available.

This device is a constant voltage device, capable of producing 10 V biphasic pulses. An optional Model 3820 stimulus isolation unit can scale and convert the output into constant current.

Full Control of Model 3800 From the Touch Screen or Windows Software

All of the Model 3800's functions can be set by the Windows software or through the LCD touch screen.
