Automated bipolar pulsing for zero net charge on biological preparations.

Benefits:
Compliance voltage is 100 V or better
Bipolar mode auto generates alternating positive and negative pulses from TTL input
Test mode simplifies performance verification
Optical isolation enhances safety of the preparation and reduces noise susceptibility
Premium warranty available

Applications:
Electrophysiology
Brain slice stimulation
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 100 V:
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.

Output current ranges: 0.1, 1.0, and 10 mA
Current amplitude error: 0.5% of full scale, max.
Current resolution: 0.1% of full scale
Output load voltage excursion: 100 V
External command threshold: 5 V at 3 mA, min. 10 V, max.
