A new addition to the GS820 source-measure units, all of which feature isolated two-channel source and measurement functions, is able to source up to 50 V and 0.6 A DC. The SMUs offer four-quadrant operation consisting of current source and current sink operation. On the 50-V model, voltage ranges are 200 mV, 2 V, 20 V, and 50 V. Current ranges are selectable from 200 nA to 1 A.
Applications for these source-measure units include tests for LED lighting and the generation of I/V curve traces for LEDs and varistors. The basic price for the new 50-V two-channel Model GS820 is $9,490. Yokogawa Corp. of America, www.rsleads.com/506ee-207
