Overview

State of the art software programmable 4 and 8 channel Stimulus Generators that ideal for applications requiring fine isolated stimulations, such as in nerve and cellular stimulation. Each stimulation channel is optically isolated (no further external isolation required) and can independently produce any arbitrary current (± 1.6mA @ 120 V) or voltage (± 8 V @ ± 20 mA) waveforms. Stimulation channels can also be triggered via a signal from the PowerLab initiated by LabChart software.

Two other current output ranges (160 µA and 16 mA) are also available by contacting your ADInstruments representative.

Supplied with:

  • 4 or 8 cables with 2 mm and 0.76 mm plugs (red)
  • 4 or 8 cables with 2 mm and 0.76 mm plugs (black)
  • 1 x shielded 3-pole cable
  • 4 or 8 short circuit-cable (black)
  • 100-240 V AC mains power unit (specify destination country when ordering)
  • MC_Stimulus II Software for Windows ONLY (Vista, Win 7 and 8 compatible)
  • User guide

Technical

Software:

The Stimulus Generators are supplied with the MC_Stimulus II software for Windows only (Vista, Win 7 and 8 compatible), which allows the creation of complex stimulus waveforms (both current and voltage). Waveforms are designed in the program (using a WYSIWYG editor) or imported from an external file. Any number of pulse shapes can be edited, managed, and stored on your computer, and downloaded to the stimulus generator when needed. Files generated by external programs are either captured by data acquisition programs or derived from complex mathematical functions in ASCII format can be imported into MC_Stimulus II software and downloaded to the stimulus generator. The waveforms can be played back by clicking start in the software, or manually pressing the start button on the stimulus generator or triggered externally. Therefore, it is not necessary to have the software program running once the waveforms are downloaded, except when more complex programming are required, the Batch mode as an example. The purpose of the Batch mode is to download different standard pulse protocol files (programmed waveforms saved in different files) to be downloaded to the stimulus generator and started in sequential order.

Waveforms:
A stimulus worksheet can be used to program 3 types of waves of any combination and permutation. Comments can also be saved and stimulus worksheets can be printed. The Waveform Types available include rectangular wave, ramp wave and sine wave.

Operating Modes:
Using the MC_Stimulus II single download or Batch mode the stimulus waveform is downloaded to the stimulus generator. In Download mode, the stimulus generator is controlled either by the MC_Stimulus II or by a custom program. In the Streaming mode you can also control the stimulus generator either by the Stimulus Streamer or by a custom program. If you use the Stimulus Streamer, you can load stimulus protocols in Mono-MP3 or binary file format of unlimited size, that were generated by a custom application and are then sent continuously from the computer to the STG in small data packets. Custom applications for the Download or the Streaming mode can be programmed in Matlab, Labview, C/C++, and Visual Basic.

Triggering:
The stimulus generators only recognize TTL (transistor-transistor logic) signals of at least 20 ìs in length and up to 5 V.
