[SOURce:] Subsystem
Example
DIG:DATA3:MON? returns a number representing the state of the data lines on
8-bit port 3.

[SOURce:]DIGital:DATAn[:type]:POLarity

[SOURce:]DIGital:DATAn[:BYTE]:POLarity <polarity> sets the data line voltage
level for logical true in port n to either TTL High for POSitive polarity or TTL Low
for NEGative polarity.
[SOURce:]DIGital:DATAn:WORD:POLarity <polarity> sets the data line voltage
level for logical true in the 16-bit port n to either TTL High for POSitive polarity or
TTL Low for NEGative polarity.
[SOURce:]DIGital:DATAn:LWORd:POLarity <polarity> sets the data line voltage
level for logical true in the 32-bit port n to either TTL High for POSitive polarity or
TTL Low for NEGative polarity.
[SOURce:]DIGital:DATAn:LW64:POLarity <polarity> sets the data line voltage
level for logical true in the 64-bit port n to either TTL High for POSitive polarity or
TTL Low for NEGative polarity.
[SOURce:]DIGital:DATAn:LW96:POLarity <polarity> sets the data line voltage
level for logical true for all ports to either TTL High for POSitive polarity or TTL
Low for NEGative polarity.
