[Source:]Digital:datan[:Type]:Handshake[:Mode] - Keysight VXI Bus 75000 C Series User And Programming Manual

[SOURce:] Subsystem
[SOURce:]DIGital:DATAn:LW64:HANDshake:DELay? queries for the delay
between data output and the control line for data output at the 64-bit port and
returns a decimal number between 0 and .015.
[SOURce:]DIGital:DATAn:LW96:HANDshake:DELay? queries for the delay
between data output and the control line for data output at the 96-bit port and
returns a decimal number between 0 and .015.
Parameters
Comments
The keyword LW32 may be used instead of LWORd.
MIN or DEF returns 0.000002. MAX returns 0.015.
DIG:DATAn[:type]:HANDshake is the sequence used for commands relating to
data handshaking at ports defined by n. The port number n must be the last
character of the keyword without spaces.

[SOURce:]DIGital:DATAn[:type]:HANDshake[:MODE]

[SOURce:]DIGital:DATAn[:BYTE]:HANDshake[:MODE] <mode> selects the type of
handshake and defines the timing relationship between the control (CTL) line, the
flag (FLG) line, and when data is transferred in either direction between the
Keysight E1458A Digital I/O Module and a peripheral on 8-bit port n.
[SOURce:]DIGital:DATAn:WORD:HANDshake[:MODE] <mode> selects the
handshake mode used on the 16-bit port n.
[SOURce:]DIGital:DATAn:LWORd:HANDshake[:MODE] <mode> selects the
handshake mode used on the 32-bit port n.
[SOURce:]DIGital:DATAn:LW64:HANDshake[:MODE] <mode> selects the
handshake mode used on the 64-bit port.
[SOURce:]DIGital:DATAn:LW96:HANDshake[:MODE] <mode> selects the
handshake mode used on the 96-bit port.
