KI2602Example_High_Current.tsp
This program is intended to perform the following:
1. Set up both SMUs of a Model 2602 for current bias and measure voltage on specific
intervals.
2. Deliver up to 2A @ 40V (1A @ 40V per SMU) by wiring each SMU in parallel
Wiring: SMUA Hi to SMUB Hi, SMUA Lo to SMUB Lo
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_sourcei value to sourcei/2. Desired current value at DUT is now
programmed.
