Catalog Number: DS4
Description: The DS4 takes an analogue voltage waveform defined within your own data acquisition/ control system and converts it into an isolated constant current stimulus. The DS4 will accept several input voltage ranges and produces four output ranges (±10"A, ±100"A, ±1mA and ±10mA). It also features a GATE input, so that several DS4 units can be controlled by a single analog waveform, but enabled individually via this GATE input. A timed "inactivity sensor" reduces battery usage and damaging "leak currents" during infrequent stimulation, while at the same time maintaining low levels of zero crossing distortion for repetitive waveforms.

Catalog Number: DS3
Description: Digitimer DS2A Isolated Constant Voltage Stimulator
Brief pulses of electricity are used in various biomedical research applications as a stimulus to excite nerve or muscle fibers. Several factors need to be considered when choosing the right stimulator.
The DS2A Mk.II provides a precise Constant Voltage stimulus (up to 100V) controllable in Pulse Duration and Amplitude from self-contained batteries, making it ideally suited to electrophysiological recording in small preparations or cells where low noise is required.

Catalog Number: DS4
Description: The DS4 takes an analogue voltage waveform defined within your own data acquisition/ control system and converts it into an isolated constant current stimulus. The DS4 will accept several input voltage ranges and produces four output ranges (±10µA, ±100µA, ±1mA and ±10mA). It also features a GATE input, so that several DS4 units can be controlled by a single analog waveform, but enabled individually via this GATE input. A timed "inactivity sensor" reduces battery usage and damaging "leak currents" during infrequent stimulation, while at the same time maintaining low levels of zero crossing distortion for repetitive waveforms.
