INPut
n
:CLOCk[:SOURce]?
Returns the programmed value of the input clock source for Port n.
Parameters
Comments • The value returned is an unquoted string of EXT or INT.
Example INPut2:CLOCk[:SOURce]?
queries the input clock source for Port 2.

Programs the input debounce time for Port n. Ports 0 and 1 share the same debounce
circuitry; Ports 2 and 3 share the same debounce circuitry.
Parameters
Comments • The available debounce times are:
18.0 µS, 36 µS, 72 µS, 144 µS, 288 µS, 576 µS, 1.13 mS, 2.26 mS, 4.6 mS, 9.2
mS, 18.4 mS, 36.9 mS, 73.8 mS, 148.0 mS, 294.0 mS, 590.0 mS, 1.18 S, 2.36
S, 4.72 S, 9.43 S, 18.9 S, 37.8 S, 75.0 S, 150.0 S, 300 S, 600 S, 1200 S, 2400 S,
4800 S, 9600 S. Any value sent other than those listed is rounded to the nearest
discrete value.
• Debounce time is rounded to the nearest discrete value. For example 16.0 µS to
18.4 µS is rounded to 18 µS, 18.5 µS to 36.4 µS is rounded to 36 µS, 36.5 µS
to 72.4 µS is rounded to 72 µS, etc.
• Ports 0 and 1 use the same debounce time, Ports 2 and 3 use the same debounce
time. For n = 0 or n = 1, both Ports 0 and 1 are set; for n = 2 or n = 3, both Ports
2 and 3 are set.
• *RST Condition: sets the value for the debounce time to 18.0µSec for all four
Ports.
