measf
This command returns the frequency sourced during a single measurement.
Usage
int measf(int instr_id, double *freq);
instr_id
The instrument identification code of the 4210-CVU: CVU1
freq
Returned frequency
Details
This command returns the present test frequency being used for a single impedance measurement.
Use the measz command to make a single measurement.
Use the smeasf or smeasfRT command to return the frequencies used for a sweep.

meast
This command returns a timestamp referenced to a measurement or a system timer.
Usage
int meast(long timerID, double *timestamp);
timerID
The instrument identification code: CVU1, TIMER1, TIMER2, and so on
timestamp
Returned timestamp
Details
This command is used acquire the timestamp of the last single measurement, or return a timestamp
referenced to a system timer.
When the timerID parameter is set for CVU1, calling the meast command after the call to perform a
measurement (measz command) will return the timestamp for that measurement.
When the timerID parameter is set for a timer, the meast command can be called at any time and
will return a timestamp that is referenced to a system timer. The enable command is used to start
the timer (starts at zero when called).
Use the smeast or smeastRT command to acquire timestamps for a sweep.
