Scale Operation Commands - Keysight 34420A User Manual

4 Remote Interface Reference
DATA:FEED RDG_STORE, {"CALCulate" | " "}
This command selects whether readings taken using the INITiate command are
stored in the meter's internal memory (default) or not stored at all.
In the default state (DATA:FEED RDG_STORE, "CALC"), up to 1024 readings are
stored in memory when INITiate is executed. The MEASure? and CONFigure
commands automatically select "CALC".
With memory disabled (DATA:FEED RDG_STORE, " "), readings taken using
INITiate are not stored. You can use this method to gather statistics on any
number of readings (no 1024 reading limit). An error will be generated if you
attempt to transfer readings to the output buffer using the FETCh? command.
DATA:FEED?
This command queries the reading memory state. Returns "CALC" or " ".
DATA:POINts?
This command queries the number of readings in memory.
