New: STG4000 Stimulus Generators for Use with PowerLab

Features of the STG4000 Stimulus Generator series include: An output voltage range of each channel between –8 V to +8 V (@ ± 20 mA), with a resolution of 1 mV An output current range of each channel between –1.6 mA to +1.6 mA (@ 120 V), with a resolution of 100 nA Optically isolated channels

Stimulus Waveforms

The supplied MC_Stimulus II software (Windows XP and Vista Compatible) allows the user to create complex stimulus waveforms (both current and voltage). The Stimulus Generators (STG) can operate in either Download Mode (protocols are downloaded onto the STG and played without a computer connection) or Streaming Mode (data are continuously sent from the computer to the STG in small data packets).

Custom applications for both modes can be programmed in MatLab, LabView, C/C++ and Visual Basic.

Triggering

The STG4000 Stimulus Generator Series can be controlled by a trigger signal from the PowerLab data acquisition system. It recognizes a TTL (transistor-transistor logic) signal of at least 20us in length and up to 5V.

STG4004 and STG4008 are supplied with:

• High Speed USB 2.0 cable (for connection to computer)
  
• 4 x cable with 2 mm and 0.76 mm plugs (red)
  
• 4 x cable with 2 mm and 0.76 mm plugs (black)
• 1 x shielded 3-pole cable
  
• 4 x short circuit-cable (black)
  
• 100-240 V AC mains power unit (specify destination country when ordering)
• MC_Stimulus II Software for Windows ONLY (XP and Vista compatible)
• User Guide

Effective immediately, all STG stimulators dispatched will be of the STG4000 series
