8.1 CNT Differential R[AC]: CNT Differential R-V characteristics (A.01.20)
[Supported Analyzer]
B1500A
[Description]
Measures the conductance of a CNT 2-terminal device and plots differential R-V (resistance vs voltage)
characteristics. This test is designed to calculate resistance as the inverse of conductance. Additionally, the level
of a measurement signal is specified by a peak-to-peak value (normally effective value).
For a more accurate measurement, perform correction data measurement at the measurement frequency before
starting the capacitance measurement.
If the measurement frequency is not included in the list of default frequencies below, click the Advanced
Options... button and set the measurement frequency on the Frequency area of the Advanced Options for CMU
Calibration window.
Default frequencies:
1 k, 2 k, 5 k, 10 k, 20 k, 50 k, 100 k, 200 k, 500 k, 1 M, 1.2 M, 1.5 M, 2 M, 2.5 M, 2.7 M, 3 M, 3.2 M, 3.5 M,
3.7 M, 4 M, 4.2 M, 4.5 M, 5 MHz
