SMU default settings
You can return SMUs to power-on default settings by transmitting the
DCL
(device clear) or
SDC
(selected device clear) general bus command to the 4200A-SCS. The power-on default settings for
the User Mode are listed in the table below.
The
DCL
command returns all instruments (including the SMUs) connected to the bus to their default
settings. The
SDC
only affects the SMUs (any other instrument on the bus is not affected). Note that
the device clear commands do not affect the KXCI configuration settings.
Use either of the following C programming commands (GPIB address 17) to return the SMUs to their
power-on default settings:
transmit ("UNL LISTEN 17 SDC", &status); // Reset 4200A only.
transmit ("DCL", &status); // Reset all instruments.
The
SDC
and
DCL
commands described above are not text-string commands, nor are any of the
other commands in this manual that are sent using the transmit function. They are low-level
commands that must be sent differently than text-string commands. Do not try to use the transmit
function to output text-string commands across the GPIB; use the send function for text-string
commands.
