Completely Software Driven

two version for complex or simple pulses available

Current and Voltage Driven Stimulation

With the MC_Stimulus software you can choose between current or voltage driven stimulation.
Decide in favour of 2, 4 or even 8 completely independent stimulus outputs

Arbitrary Analog Waveforms

freely combine mono- or biphasic rectangular pulses, ramps, or sine waveforms to design a stimulation pattern of unlimited complexity.
You can do this on each output channel.

Integrated Isolation Units

Each of the 2, 4 or 8 output channels is optically isolated, efficiently avoiding cross-talk among channels.
No additional units, batteries and cables, no additional costs!

Each Channel - All Features - Full Flexibility

Each of the 2, 4 or 8 channels is completely independent.
For all kinds of stimulation patterns- there's no need to combine channels. Every single channel can be used for a complex stimulus output.
 
Three functions- One device

  • Current driven stimulation:
    In current mode, the stimulus generator guarantees a stable current output in the range of -1.6 mA to +1.6 mA independent of the electrode impedance @ 120V compliance voltage.
    On request, a version with an extended output range of ± 16 mA is available.
  • Voltage driven stimulation:
    In voltage mode, the voltage level in the range of -8 V to +8 V is held constant and the current output depends on the electrode impedance. The lower the electrode impedance - the higher the output current.
    The maximum output current is ± 20 mA.
  • Controlling and Timing:
    For every single stimulus output there is one TTL in- and output. The Stimulators can receive and deliver TTL pulses via BNC connectors.
    These triggers allow you to control and synchronize other instruments like imaging systems, LED-lights, data acquisition systems and many more - at a 20μs precision.
