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.

Usage
address = gpib.address
gpib.address = address
address
GPIB address (0 to 30)
Details
A new GPIB address takes affect 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 GPIB address is stored in nonvolatile memory. The reset function has no affect on the address.
Example
gpib.address = 26
address = gpib.address
print(address)
Sets the GPIB address and reads the address.
Output:
2.600000e+01
