MEASure Subsystem
MEASure:DIGital:DATAn:LW96[:VALue]? reads 12 bytes from the 96-bit port after the
completion of the handshake and returns three decimal numbers, each between
-231 and (231-1).
Parameters

Examples
MEAS:DIG:DATA1? reads 8-bit port 1 data. If all data lines are set to 1, this
command returns the value 255.
MEAS:DIG:DATA0:LW64? reads 64-bit port 0 data. If all data lines are set to 1, this
command returns the values -1 and -1.
MEAS:DIG:DATA0:LW96? reads 96-bit port 0 data. If all data lines are set to 1, this
command returns the values -1, -1 and -1.

– ? Input data from the digital I/O module is returned in decimal format.
Other formats are not supported for input. However, data output to the
digital I/O module may be in binary, octal, decimal, or hexadecimal.
– ? If n is omitted, the port number is set to 0.
– ? The keyword LW32 may be used instead of LWORd.
– Chapter 3, "Using the Keysight E1458A Digital I/O Module," describes the
byte order of mutltiple-byte reads.
– ? :DATAn is the keyword used for commands relating to the data at port n.
The port number n must be the last character of the keyword without
spaces.
