  1. DS2A Isolated Voltage Stimulator

    Brief pulses of electricity are used in various biomedical research applications as a stimulus to excite nerve or muscle fibres. In order to minimise artefacts introduced into electrophysiological data, it is desirable that the stimulator (stimulus isolator) used should be electrically isolated both from ground and from the trigger device. The DS2A meets both of these requirements and will deliver a low noise, precisely controlled constant voltage stimulus of up to 100V, adjustable in pulse duration and amplitude. As with the DS3 Constant Current Stimulator the output comes from self-contained batteries. The DS2A can be triggered by a TTL compatible external device such as our new DG2A Train/Delay Generator. The DS2A can be fitted into a 19" rack mounting frame (D121-11) which can hold up to two DS2A's, DS3's DS4's or DG2A's.
