The NL800A Current Stimulus Isolator from Digitimer is a battery powered, opto-coupled isolator (replacing the NL800), which has been designed for low noise applications such as in vitro and in vivo electrophysiology. It has a constant current output, with very high output impedance, making it suitable for stimulation through microelectrodes as well as with gross electrodes.
Normally driven from the NL510A PULSE BUFFER, its output current is set by the 10-turn AMPLITUDE control on the NL510A, within the output range set by the switch on the NL800A. Output pulses have the same timing as the input pulses (2 microseconds to 30 seconds output pulse width).
Features of the NL800A are its very small physical size (for mounting close to the preparation), low battery consumption, excellent isolation (<1pF output to input or ground coupling), and fast pulse risetime. The NL800A is a replacement for the NL800 which used different batteries but had the same electronic circuit. The NL800A is NOT designed for nor recommended for human use
In the normal operating mode, an NL510A PULSE BUFFER produces the appropriate input pulses. The NL800A Power switch is turned on, the output range is selected and the desired output amplitude is produced at the two output terminals by adjusting the amplitude (10 turn) dial on the NL510A. The output can be checked by measuring the voltage across a 1kohm resistor, connected between the output terminals, with an oscilloscope or voltmeter (1V = 1mA).
The NL800A requires an input that varies between approximately +1.4V and +10V, 0 to +30mA, corresponding to NL800A outputs of 0 to full scale.
The NL512 Biphasic Pulse Buffer has been designed to allow two (2) NL800A’s to be used to produce a bipolar stimulation signal.
