Details
See settimezone() for additional details about the time zone format and a description of the fields.
timeZone can be in either of the following formats:
â–ª If one parameter was used with settimezone(), the format used is:
GMThh:mm:ss
â–ª If four parameters were used with settimezone(), the format used is:
GMThh:mm:ssGMThh:mm:ss,Mmm.w.dw/hh:mm:ss,Mmm.w.dw/hh:mm:ss
Example
Reads the value of the local time zone.

gm_isweep()
This KIParlib factory script function performs a linear current sweep and calculates the transconductance (G
m
) at
each point.
Usage
gm_array, vbuf, ibuf = gm_isweep(smu, start_i, stop_i, points)
A Lua table containing the calculated G
m
values at each point
A reading buffer containing the measured voltage at each point
A reading buffer containing the measured current at each point
Instrument channel (for example, smua refers to SMU channel A)
Starting current level of the sweep
Ending current level of the sweep
Number of measurements between start_i and stop_i (must be ≥2)
Details
Output data includes transconductance values, reading buffer with measured voltages, reading buffer
with measured voltages and currents.
If all parameters are omitted when this function is called, this function is executed with the parameters
set to the default values.
The gm_isweep() function performs a linear current sweep, measuring voltage and current, and
then calculating the transconductance (G
m
) at each point using the central difference method. It can
return an array of G
m
values, a reading buffer with the measured voltages, and a reading buffer with
the measured currents.
