MEASure:DIGital:DATAn:BYTE:BITm? reads the state on bit m of 8-bit port n
after the completion of the handshake.
MEASure:DIGital:DATAn:WORD:BITm? reads the state on bit m of 16-bit port n
after the completion of the handshake.
MEASure:DIGital:DATAn:LWORd:BITm? reads the state on bit m of the 32-bit
port n after the completion of the handshake.
Parameters
Comments • Input data is always assumed to be in binary format, since only a single bit of
data is being read. The command returns either a 0 or 1.
• The keyword :LW32 may be used instead of :LWORd when using the
downloaded version of the SCPI driver.
• :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.
