Program 16. High Voltage with Current Measurement
--[[
KI2602Example_High_Voltage.tsp
This program is intended to perform the following:
1. Set up both SMUs of a Model 2602 for voltage bias and measure current on specific
intervals.
2. Deliver up to 80V @ 1A (40V @ 1A per SMU) by wiring each SMU Voltage Source in
series.
Wiring: SMUA Lo to SMUB Hi, SMUA Hi to DUT, SMUB Lo to DUT
WARNING: If either SMU reaches a compliance state, the instrument, device, or both
could be damaged.
System Requirements: 260x Firmware version: 1.0.2 or newer
Rev1: JAC 3.21.2006
Rev2: JAC 10.15.2007
-Change l_sourcev value to sourcev/2. Desired voltage value at DUT is now
programmed.
