The application of voltage and/or digital stimulus pulses is handled by the controls on the Stimulator page.
Stimulus Protocols
To generate a stimulus waveform, select a stimulus protocol from the Stimulator list and click the Start button. (Stimulus protocols are also started automatically when the Record button is pressed.) Clicking the Stop button terminates the stimulus and returns the output voltage to the holding level. Click the Set Stim. Folder to change the folder holding the stimulus protocol files.
Stimulus protocols can consist of a series of one or more pulses, incremented in amplitude or duration to create a family of pulses. Complex stimulus waveforms can be produced, including series of rectangular steps, ramps, and digitised analogue signals. Individual protocols can also be linked together to automatically apply a series of different protocols during an experiment. Protocols are created using the Stimulus Protocol Editor and stored as protocol files (*.vpr files). (See section ?)
V Hold (Default)
The holding voltage applied to each voltage stimulus channel (VOut 0-2) can be set by entering a new voltage into the appropriate box for each channel and pressing the Enter key. (Note. Stimulus voltages waveforms generated during a voltage protocol are added to the holding voltage. To record to file a series of images (with signals if analogue channels are defined):
