3 First Use of the Stimulus Generator
3.1 Welcome to the STG and MC_Stimulus
Product line overview
Stimulus generators of the 1000 and 2000 series are
general/purpose stimulators designed to serve a very wide variety
of applications, both in vitro and in vivo.
Flexible and easy-to-use MC_Stimulus software enables complex
stimulus waveforms (both current and voltage). Waveforms
designed in the program or imported from an external ASCII file
are converted by the connected STGs into pulses, which are sent
to stimulating electrodes. Stimulus isolation units (SIU) for each
channel are included. Thus, no external SIUs are required.
A trigger input and output for TTL signals allows to synchronize the stimulus generator with other
instruments. Triggering of other devices via programmable TTL pulses (Sync Out) is possible, as
well as triggering of the STG by external devices via the Trigger In input. For example, you can
synchronize stimulation and recording with a digital trigger signal sent from the Sync Out
output of the STG to the MC_Card.
Stimulus generators are available for simultaneous stimulation on up to 8 channels
(STG1001STG1008, STG2004, STG2008).
2000 Series
The real-time stimulus generator of the 2000 series is an advanced version and the world's first
STG that is able to send continuous pulse streams to stimulating electrodes. In addition, you can
trigger all (up to 8) channels separately by external TTL pulses. 4 trigger inputs (Trigger In)
and4 trigger outputs (Sync Out) are shared by 8 channels in the 8-channel version.
MC_Stimulus
Stimuli are created user-friendly by entering the desired pulses (rectangular, ramp, or sine
waveforms) into a worksheet. Waveforms can be combined freely to create virtually any stimulus
pattern.
Created stimuli are displayed in a WYSIWYG stimulus display. All channels are set up
separately.
For even more convenience, repetitive stimulus patterns do not have to be entered separately,
but can be grouped and looped. You can also import waveforms in ASCII file format and use
them for stimulation. You can print and save stimuli and comments for later use and
documentation of your experiments.
