[SOURce:]DIGital:HANDshaken:DELay
[SOURce:]DIGital:HANDshaken:DELay <time> sets the time between data valid
and the assertion of the control line to TRUE for port n. This form of the
command operates on 8-bit ports only.
Parameters
The controller uses a rounded-up value for <time> if these values are specified.

–
:HANDshaken is the keyword used for commands relating to data
handshaking at port n. The port number n must be the last character of the
keyword without spaces.
–
The delay time must be set to the same value on all ports used in a
multiple-port operation.
–
MAX sets a 15-ms delay. DEF sets 2-µs delay. MIN sets a delay of 0.
Because of hardware ambiguity at this delay setting, the actual delay is not
guaranteed. Note that MIN is illegal for PULSe or STRobe handshakes.
–
This command sets the strobe pulse width for both input and output
STRobe handshakes.
–
DIGital:HANDshaken NONE command ignores any programmed delay
time. For all other modes of handshaking, 2 µs is the minimum.
–
Specific bands of delay settings are not allowed. These are:
0 µ s > <time> < 2 µ s
15 µ s > <time> < 20 µ s
150 µ s > <time> < 200 µ s
1.5 ms > <time> < 2.0 ms
