3 First Use of the Stimulus Generator
3.1 Welcome to the STG3008-FA and MC_Stimulus II
Product Line Overview
Stimulus generator of the 3000 series are general purpose stimulators designed for a wide variety
of applications, both in vitro and in vivo. The STG3008-FA is a special version for use with
cardiovascular catheter microelectrodes for animals.
The STG is additionally equipped with a filter amplifier FA and has the advantage that the device
can be used for both, for stimulation and for recording. You switch software controlled between
the two operation modes recording and stimulation.
The filter amplifier of the STG3008-FA provides four different gain factors 100, 200, 500, or 1000
and has a band pass filter with a bandwidth of 1 Hz to 2,2 kHz.
The stimulus generator STG3008-FA is available for simultaneous stimulation on up to eight
completely independent stimulation channels. Each channel is freely programmable, combination
of channels to achieve complex stimulation patterns is not necessary.
Flexible and easy-to-use MC_Stimulus II software enables complex stimulus waveforms (both
current and voltage) in Download mode and Streaming mode. Waveforms designed in the
program or imported from an external ASCII file are converted into pulses, which are sent to
the stimulation electrodes.
Note: Please note that not all software features of MC_Stimulus II are supported by the hardware.
A trigger input and a Sync 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 TTL signal sent from the
Sync Out output of the STG to the data acquisition system, for example, the MC_Card or
an USB based data acquisition system.
The real-time stimulus generator STG3008-FA has two operating modes: Download mode
and Streaming mode.
In Download mode, you can control the STG either by the MC_Stimulus II or by a custom
program. Stimulus protocols are created in MC_Stimulus II or the custom program; complete
protocols are downloaded onto the STG, and can after the download be executed without
a computer connection.
