8.7 CNT IV Sweep: CNT Differential I-V characteristics (A.01.20)
[Supported Analyzer]
B1500A, 4155B, 4155C, 4156B, 4156C
[Description]
Measures the I-V (current vs voltage) characteristics of a CNT 2-terminal device.
This test definition allows one to select the direction of a sweep from "Single" and "Double." When the sweep
start/stop value is not 0 V, outputs a sweep from 0 V to the start value or from the stop value to 0 V to protect a
device.
