SYS-A320D  Isostim Stimulator/Isolator
 
  • Easy-to-use
  • Dual tone audible alarm
  • Designed for Neuroscience & Muscle applications
 
 
Timing

Pulse interval and width are set with single-turn continuously variable controls from 5 ms to 5.5 s in three ranges. Pulse width is continuously variable from 50 µs to 550 ms in four ranges.

Modes of Operation

In FREE RUN, Isostim™ generates continuous square waves. In EXT?GATE or EXT SYNC modes, externally applied pulses can generate trains or single events. Single pulses of finite duration can be produced using a push-button on the instrument’s front panel. EXT/DC mode converts Isostim to a passive stimulus isolator.

Dual Tone Audible Alarm

A tone sounds when an open circuit is detected or when system compliance is reached. A second tone, which sounds when a signal is applied to the input, can only be heard if the batteries have sufficient charge to operate the isolator. A violation light advises when pulse width exceeds the interval.

Current Delivery

Stimulus currents up to 10?mA can be set on the front panel with a control knob and a two-position range switch. Output current is load-independent.

Power

Isostim model A320D is powered by readily obtainable 9-volt alkaline batteries (included). Under average use these will last several months before replacement is required.
