Universal Isolated Stimulator Output
- Generates isolated Stimuli in the range of 0-100 Volt
- Can be connected to any stimulator delivering a trigger signal
- Can be used in combination with a trigger output generated by a computer software as a power amplifier
Applications:
- Electrophysiology
- In case of simultaneous biopotential recording
This unit is required to produce ungrounded (isolated or floating)
stimuli and prevent interference in any biopotentials (ECG, EMG,
EEG etc.) which are recorded simultaneously. It can be connected
to virtually any type of stimulator delivering a trigger pulse
with the same width as the stimulus duration. The input for the
trigger impulse is a BNC socket on the back plane. It can also
be connected to a TTL trigger output generated by a software
on a computer as a power amplifier. A switch selects the output
amplitude range (0-50, 0-l00 Volt). Fine adjustment is provided
by the fine control on a 10-turn Potentiometer Stimuli produced
can be either monopolar (positive or negative), or alternated.
Alternated stimulation avoids electrode polarisation.
| Trigger Signal |
3 to 15 Volt, Triggerlevel 1.5 Volt,active low or active high (can be switch internally using a jumper) |
| Trigger Input Impedance |
