DIGITIMER - DS3 İzole Akım Stimülatörü

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
  • DESCRIPTION
  • 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. With the four ranges (x10μA; x100μA; x1mA and x10mA), currents from 2μA to 32mA can be selected. The existence of an output pulse is indicated by an LED. The Output is optically isolated from the trigger source ensuring a very low capacitive coupling between trigger source and stimulator to reduce artifacts. The self-contained batteries, without a DC-DC converter, ensure that the stimulator is ultra-quiet and does not induce any high-frequency noise into the recording system.
  • It is worth noting that battery current is only drawn when the stimulator is delivering an output pulse. This greatly extends the life of the batteries. When constant current stimulators are used to stimulate very high-impedance, high capacitance cells the electrode tip can charge up and stimulation be lost. This is because constant current stimulators have a very high output impedance which will not discharge the cells. The DS3 provides an output discharge circuit which operates (if user enabled) after each stimulus pulse. An internal jumper selects this feature.
  • The DS3 can be triggered by an external device such as our new DG2A Train/Delay Generator. The DS3 can be fitted into a 19″ rack mounting frame (D121-11) which can hold up to two DS3s.
