The MEASure and CONFigure Commands
Each time the counter takes a measurement it does so from a configuration based
on multiple parameters. The easiest and most common starting point for setting
these parameters programmatically is using commands within the CONFigure
and MEASure subsystems. These commands are considered “high-level”
commands as multiple counter parameters are set or defaulted from a single
command. “Low-level” commands are those within other subsystems (i.e. INPut,
TRIGger, SENSe) that allow you to change a parameter value from that set, or
defaulted to, using CONFigure or MEASure.
Executing commands from the CONFigure and MEASure subsystems is equivalent
to setting parameters individually using the commands/subsystems shown in
Table 3-2.
