Description
Digitimer DS3 Isolated Current Stimulator
The DS3 provides a precise constant current, isolated stimulus, controllable in pulse duration and amplitude from self-contained batteries. The range of pulse durations available can be varied using a six-position switch and multiplier within the range 20 microseconds to 2 seconds as well as being externally controlled (gated). A three-turn dial on the front panel of the stimulator provides a continuous adjustment of the output amplitude which is indicated on the vernier dial as 0.2 to 3.2.
Features:
- Low noise battery power supply with 90V compliance
- Internal (20µs to 2s) or external TTL “gated” control of pulse duration
- Four current ranges allow precise reproducible control of stimulus output between 2µA and 32mA
- Polarity reversal switch
- Battery test sockets
In good operating condition, images form part of the description.
