• Coupled command: VINStrument:CONFigure:LBUS:SEND:POINts:AUTO and
VINStrument:CONFigure:LBUS:FEED settings determine the allowable values
of this command.
• For a more complete discussion and example of when this command should be
used, see "Local Bus Data Transfers" in Chapter 3.
• If a measurement was halted using the ABORt command and "MEM:xxx" is one
of the VINStrument:CONFigure:LBUS:FEED choices, the query form of this
command will return the number of points that will actually be transferred
(assuming VINStrument:CONFigure:LBUS:SEND:POINts:AUTO ON) when the
VINStrument:CONFigure:LBUS:MEMory:INITiate command is invoked.

[:CONFigure]:LBUS:SEND:POINts:AUTO
VINStrument[:CONFigure]:LBUS:SEND:POINts:AUTO <mode > determines
how the digitizer will send its data over the Local bus. In most cases AUTO ON
would be used, which sends all of a measurement’s data over the Local bus followed
by an end-of-block flag and an end-of-frame flag.
The AUTO OFF setting is a special setting which is only used when it is desirable
for multiple digitizers to output A/D data from each (common) trigger event onto
the Local bus at approximately the same time (i.e. in parallel). In this mode, the
end-of-block and end-of-frame flags are sent with each reading (trigger event). This
mode requires that all digitizers are set to the same trigger count and have their
trigger sources synchronized such that each digitizer’s data is available to the Local
bus before the next trigger event can occur on any digitizer in the data stream.
Otherwise, data loss will occur and an error will be indicated by one or more of the
digitizers.
