INPUT:DEBOUNCE

The INPut:DEBounce command sets the time period for the digital debounce circuitry. This command affects all the 16 channels of the instrument. It is important to note that the debounce resolution is 9.6 ∝s.

INPut:DEBounce <value>	Where <value> ranges from 9.6 ∝s, i.e.,
	0.0000096 s to 0.6291456 s.

EXAMPLES
INPut:DEBounce 9.6e-6	Sets the input debounce time for all
	channels to 0.0000096 s. This will not
	allow a signal to generate an interrupt
	unless the input signal crosses the signal for
	more than 9.6 e-6 seconds.
INP:DEB 0.6	Setting input debounce time to 0.6 s.
INP:DEB?	Returns the input debounce time as 0.6 s.
0.6
