smeast
This command returns timestamps referenced to sweep measurements or a system timer.
Usage
int meast(long
timerID
, double *
tarray
);
timerID
The ID of the 4210-CVU or timer:
CVU1
,
TIMER1
,
TIMER2
, and so on
tarray
Returned array of timestamps
Details
This command acquires the timestamp for each measurement step of a sweep. The timestamps are
returned in an array. The timestamps are posted to Clarius Analyze after the test has finished.
You can also use the
smeastRT
command to return timestamps in an array. It posts the frequency
values to Clarius in real time.
The timestamp can be referenced to the 4210-CVU (
timerID
=
CVU1
) or to a system timer (for
example,
timerID
=
TIMER1
). This command is similar to the
meast
command, but is synchronized
with a sweep to return a timestamp referenced to each measurement. If you need a timestamp for a
single measurement, use the
meast
command.
LPT maintains a list of measurements to be done at each sweep point after the forcing instrument
has stepped its source (V, I, or F). The
smeasX
and
smeas
X
RT
commands register the
measurement with a master list. If the time measurement precedes the Z measurement, then the
wrong timestamp is returned (the one from the previous measurement).
Example
(on page 13-195) acquires a timestamp for each measurement in the
sweep.
