| Description |
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
The rechargeable A320R is supplied with a nickel metal hydride battery stack which provides 10-12 hours of operation before recharge is required. The A362 Battery Charger must be used with the A320R. |
