scnmeas
This command makes a single measurement on multiple instruments at the same time.
Usage
int scnmeas(void);
Details
This command behaves like a single point sweep. It makes a single measurement on multiple
instruments at the same time. Any forcing or delaying must be done before calling
scnmeas
.
smeas
X
,
sintg
X
, or
savg
X
must be used to set up result arrays just as is done for a sweep call.
Each call to
scanmeas
adds one element to the end of each array.
Calls to
scnmeas
may be mixed with calls to
sweep
X
, and all results are appended to the result
arrays in the same way multiple
sweep
X
calls behave.

searchX
This command is used to determine the voltage or current required to get a current or voltage. It is useful in
finding initial threshold points such as junction breakdown or transistor turn on.
Usage
int searchi(int
instr_id
, double
min_val
, double
max_val
, long
iterate_no
, double
iterate_time
, double *
result
);
int searchv(int
instr_id
, double
min_val
, double
max_val
, long
iterate_no
, double
iterate_time
, double *
result
);
instr_id
The instrument identification code of the sourcing instrument
min_val
The lower limit of the source range
max_val
The upper limit of the source range
iterate_no
The number of separate current or voltage levels to generate; the range of iterations
is from 1 through 16
iterate_time
The duration, in seconds, of each iteration
result
The floating point variable assigned to the search operation result; it represents the
voltage, with the
searchv
command, or current, with the
searchi
command,
applied during the last search operation
