175 – Stimulus Isolator Guidelines – STMISOC

MP150 and MP100 System stimulation features provide a powerful vehicle for outputting a variety of waveforms of varying duration, coincident with the data acquisition process. Often, a stimulation voltage in excess of 20 v (p-p) is required to perform nerve or muscle stimulation. This application note will focus on using the STMISOC for either voltage or current stimulation, when higher stimulation voltages or compliance is important. This application note will identify the hardware and software setup procedures when using the STMISOC with an MP Research System.

The voltage monitor output on the STMISOC shares output stimulus ground (Vout-).  In cases where continuous output stimulus monitoring also requires isolation from MP150 input, it’s recommended to use one each of:
CBL100
INISO
HLT100C
to isolate the voltage monitor feedback signal from the MP150 input.
