The MEASure? and CONFigure Commands
scan_list
MEASure:DIGital:BYTE? ( @ < >)
Configure the instrument to read the specified digital input channels on
the multifunction module and immediately sweep through the scan list
one time. Note that this command also redefines the scan list. The readings
are sent directly to the instrument's output buffer but the readings are
not stored in reading memory. The digital input channels are numbered
"s01" ( LSB ) and "s02" ( MSB ), where s represents the slot number.
Note that if you include both digital input channels in the scan list,
the instrument will read data from both ports simultaneously with the
same time stamp. This will allow you to externally combine the two
8-bit value into one 16-bit value.
scan_list
MEASure:TOTalize? {READ|RRESet} ,( @ < >)
Configure the instrument to read the count on the specified totalizer
channels on the multifunction module and immediately sweep through
the scan list one time. Note that this command also redefines the scan list.
The readings are sent directly to the instrument's output buffer but the
readings are not stored in reading memory. The totalizer channel is
numbered "s03", where s represents the slot number.
To read the totalizer during the scan without resetting the count, select
the READ parameter. To read the totalizer during the scan and reset the
count to "0" after it is read, select the RRESet parameter (this means
"read and reset").
