:DATA[:DATA]
Syntax
:DATA[:DATA] {VMON|IMON|BUF[1-3]|REF1|REF2}
:DATA[:DATA]?
Description
Reads out the current monitor value or voltage monitor value of the measured signal or the
data in data buffer 1, data buffer 2 or data buffer 3. Executing this command rewinds the
pointer to the specified data buffer (the location to feed measurement data) to the start.
The transfer format of data read out with this command conforms to the setup made with
Parameters
If the specified parameter is out of the allowable setup range, the minimum value (if the
lower limit of the range is not reached) or the maximum value (if the upper limit of the
range is exceeded) is set.
