Features
Activated by conventional logic-level commands, Model A365 can be gated by any pulse generator, stimulator, or computer output.
Dual Tone Audible Alarms
A tone sounds when an open electrode circuit is detected or when system compliance is reached. A second optional tone sounds when a signal is applied to the input. A test switch is also provided to check battery charge.
Current Delivery
Stimulus currents are set using a three-digit control knob and a three-position range switch. Output current tracks control settings to better than 1%. Output current is load independent; voltage sufficient to push the desired current through the load is automatically developed, subject only to compliance limits. Model A365 produces up to 10 milliampere current, in three ranges, at more than 100 volts compliance.
Polarity
Output polarity is determined by a push switch on the front panel.
Bipolar Pulsing
Bipolar current is toggled by the command waveform, setting alternating pulses as positive or negative.
