Syntax
DATA:POINts?
Description Query the total number of readings currently stored in the reading memory.
Explanation  You can send this command to query the total number of readings during or after a
scan.
 During the scan, you can store at most 10,0000 readings and all the readings are
automatically time stamped. If the memory overflows, bit12 in the questionable
status register will be set to 1 (refer to the
STATus:QUEStionable:CONDition?
command
and the new readings will overwrite the oldest readings stored.
 Bit12 in the questionable status register will be cleared when the memory is cleared.
Note that bit12 in the questionable status register will not be cleared if the memory is
emptied with the
DATA:REMove? or R? command.
 The reading operation does not clear the readings in the memory. The instrument
clears all the readings in the memory when a new scan is initiated, after a Factory
Reset (the
*RST command) or after an Instrument Preset (the SYSTem:PRESet
command).
Return
Format
The query returns an integer from 0 to 10,0000.
Example
DATA:POIN?
The query returns +20579.
