Chapter 5
DIGital:HANDshaken:DELay?
[SOURce:]DIGital:HANDshaken:DELay? queries for the time between data valid
and the assertion of the control line to TRUE. This command operates on 8-bit ports
and returns a decimal value between 0 and 0.015.
Parameters
Comments • The delay time must be set to the same value on all ports used in a multiple
port operation.
• :HANDshaken is the keyword used for commands relating to data
handshaking at 8-bit port n. The port number n must be the last character of the
keyword without spaces.
• MIN or DEF returns 0.000002. MAX returns 0.015.
Example DIG:HAND0:DEL? queries the delay time between data valid and the assertion of
the control line to TRUE on 8-bit port 0.
DIGital:HANDshaken[:MODE]
[SOURce:]DIGital:HANDshaken[:MODE] <mode> selects the type of handshake
mode to use to transfer data in either direction between the Digital I/O module and a
peripheral on 8-bit port n. Handshakes are initiated by execution of a
DIGital:DATAn
or
MEASure:DIGital:DATAn? command. This form of the HANDshake command
operates only on 8-bit ports.
Parameters
Comments • :HANDshaken is the keyword used for commands relating to data
handshaking at port n. The 8-bit port number n must be the last character of the
keyword without spaces.
• NONE deletes all automatic data handshaking between the Digital I/O Module
and peripheral. For custom handshaking, the control and flag lines are
controlled by the
DIGital:CONTroln and DIGital:FLAGn commands.
• Related Commands: [SOURce:]DIGital:HANDshaken:DELay,
[SOURce:]DIGital:CONTroln:POLarity
• *RST Condition: Mode is NONE on all ports.
Example DIG:HAND3 LEAD sets the handshake mode to LEADing on 8-bit port 3.
