Details
Output data includes transconductance values, reading buffer with measured currents, reading buffer
with measured currents and voltages.
The
gm_vsweep()
function performs a linear voltage sweep, measuring voltage and current, and
then calculating the transconductance (Gm) at each point using the central difference method. It can
return an array of Gm values, a reading buffer with the measured currents, and a reading buffer with
the measured voltages.
Example
gm_array = gm_vsweep(smua, 0, 5, 20)
gm_array, ibuf = gm_vsweep(smua, 0, 5, 20)
gm_array, ibuf, vbuf = gm_vsweep(smua, 0, 5, 20)
SMU A returns Gm values only.
SMU A returns Gm and reading buffer
with measured currents.
SMU A returns Gm and reading buffers
with measured currents and voltages.

address
The GPIB address of the instrument (0 to 30)
Details
The address can be set to any address value from 0 to 30. However, the address must be unique in
the system. It cannot conflict with an address that is assigned to another instrument or to the GPIB
controller.
A new GPIB address takes effect when the command to change it is processed. If there are response
messages in the output queue when this command is processed, they must be read at the new
address.
If command messages are being queued (sent before this command has executed), the new settings
may take effect in the middle of a subsequent command message, so care should be exercised when
setting this attribute from the GPIB interface.
You should allow ample time for the command to be processed before attempting to communicate
with the instrument again. After sending this command, make sure to use the new address to
communicate with the instrument.
The
reset()
function does not affect the GPIB address.
