STG2000 Series
The stimulus generator of the 2000 series includes all approved features of the 1000 series. It is an even more advanced version and the first real-time stimulator with dynamic online changes and downstreaming of pulse protocols on the market, only available from MCS. The USB interface and an improved transfer protocol result in a greatly reduced download time - 100 times faster than before!

The stimulus generator of the 2000 series includes all approved features of the 1000 series. It is an even more advanced version and the first real-time stimulator with dynamic online changes and downstreaming of pulse protocols on the market, only available from MCS. The USB interface and an improved transfer protocol result in a greatly reduced download time - 100 times faster than before!
Stimulus length is not limited, and stimuli can be flexibly changed in real time during an experiment. Even white-noise patterns are possible.
Waveforms (both current and voltage) designed in the MC_Stimulus program or imported from an external file are converted by the stimulus generator into pulses, which are sent to stimulating electrodes. Stimulus isolations units (SIU) for each channel are already integrated in the compact instrument.
All (up to 8) channels can be triggered independently by external TTL pulses. 4 trigger inputs are shared by 8 channels in the 8-channel version.
Triggering of other devices (for example the data acquisition) via programmable TTL pulses sent from the four additional Sync Out outputs of the stimulus generator is possible.
Stimulus generators of the 2000 series are available for simultaneous stimulation on 4 and 8 channels (STG2004 and STG2008).
New Advanced Features:
- Dynamic online changes and downstreaming of pulse protocols
- 4 additional trigger inputs and outputs
- Each channel can be triggered independently
- USB 1.1 interface
- Download rate (from computer to stimulus generator) 12 Mbps
- Extra large memory for complex and long pulse protocols
- Free DLL - STG can be controlled from custom programs
Waveforms and stimulation:
- Unlimited duration of stimulus protocol and number of pulses, perfect
for long-time stimulation
- Freely programmable waveforms (monophasic, biphasic, square pulses,
ramps, sine wave)
- Individual time rates and duration of pulses
- ASCII Import of stimulation protocols (e. g. biopotential waveforms)
- Time resolution 20 µs
- Very accurate/flexible timing controlled by an internal microcontroller
- Continuous or triggered operation
Hardware:
- Stimulus isolation units integrated for each channel
- 4 or 8 analog output channels, each operating independently
- Each channel optically isolated
- Separate voltage and current output mode
- Maximum output voltage -8 V to +8 V @ +/-20 mA for each channel
- Maximum output current -0.8 mA to 0.8 mA @ +/-100 V for each channel
- Downloaded paradigms are stored in internal memory and transformed by
the STG's internal computer into analog pulse streams
- Advanced microprocessor technology
- Plug and play hardware
- No need for batteries
Software:
- Very flexible design of simple and complex stimulation protocols via
graphical user interface and WYSIWYG editor (for Windows)
- Tools for setting up complex stimuli like autocreating wizards, editing
multiple pulses at once, grouping and looping pulses
- Save comments and print stimulus worksheets
- Edit, manage, and store any number of pulse paradigms on your computer,
download them to STG as needed
- Batch mode for combining separate standard pulse protocol files for
different applications
