Experimental Interface for Rustrak 288 Unit

(1-28-1992)
 

Remarks:

(1) A 3 diode 'pair' off-set is included -- which is switchable; no diode, 1-diode, 2 diodes, or 3 diodes. Each diode pair introduces about 0.7 volts of off-set. pairs are used in case polarity reversal occurs in some tests.

(2) The 5k series resistor, R_s, is used to establish a voltmeter range betwen 0.5 & 5 volts, adjustable as needed for the GW circuit parameters used.
