- In vivo brain and CNS stimulation
Activated by conventional logic-level commands, Model A365 can be gated by any pulse generator, stimulator or computer output with automated bipolar pulsing for zero net charge on biological preparations.
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 up to 10 mA at more than 100V
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, and voltage sufficient to push the desired current through the load is automatically developed, subject only to compliance limits. Model A360LA produces up to 10 mA current, in three ranges, at more than 100 V compliance.
Bipolar Output Polarity
Output polarity is determined by a push switch on the front panel. Bipolar current is toggled by the command waveform, setting alternating pulses as positive or negative.
Power
This A365RC Stimulus Isolator includes both the A365R Stimulus Isolator and the A362 battery charger.The rechargeable A365R is supplied with a nickel metal hydride battery stack. The A362 Battery Charger is required with the A365R.
