Chapter 5
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
Comments • :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.
• This command sets the strobe pulse width for both input and output STRobe
handshakes.
• The delay time must be set to the same value on all ports used in a multiple
port operation.
• MAX sets a 15ms delay. DEF sets 2µs delay. MIN sets a delay of 0, and is illegal
for PULse and STRobe handshakes.
• DIGital:HANDshaken NONE command sets the delay to 0. For all other
modes of handshaking, 2
µs is the minimum.
• Specific bands of delay settings are NOT allowed. These are:
0
µs> <time> <2µs 150µs> <time> <200µs
15
µs> <time> <20µs1.5ms> <time> <2.0ms
The controller uses a rounded-up value for
<time> if these values are specified.

[SOURce:]DIGital:HANDshaken[:MODE]
• *RST Condition: Delay is set to 2 µs.
Example DIG:HAND3:DEL .005 sets the delay between the data output and the assertion of
the control line to true on 8-bit port 3 to 5 ms.
