This command resets all active instruments in the system to their default states.
Usage
int devint(void);
Details
Resets all active instruments in the system to their default states. It clears the system by opening all
relays and disconnecting the pathways. Meters and sources are reset to their default states. Refer to
the hardware manuals for the instruments in your system for listings of available ranges and the
default conditions and ranges.
The
devint
command is implicitly called by the
execut
command.
To abort a running
pulse_exec
pulse test, see
dev_abort
.
devint
does the following:
1.
Clears all sources by calling
devclr
.
2.
Clears the matrix crosspoints by calling
clrcon
.
3.
Clears the trigger tables by calling
clrtrg
.
4.
Clears the sweep tables by calling
clrscn
.
5.
Resets GPIB instruments by sending the string defined with

devint
is implicitly called by
execut
and
tstdsl
.
devclr
is implicitly called by
clrcon
.
