Details
When this command is set to on, the timer performs the delay operation.
When this command is set to off, there is no timer on the delay operation.
You must enable a timer before it can use the delay settings or the alarm configuration. For expected results
from the timer, it is best to disable the timer before changing a timer setting, such as delay or start seconds.
To use the timer as a simple delay or pulse generator with digital I/O lines, make sure the timer start time in
seconds and fractional seconds is configured for a time in the past. To use the timer as an alarm, configure the
timer start time in seconds and fractional seconds for the desired alarm time.
Example 1
TRIG:DIG3:OUT:STIM TIM2
SYSTem:TIME?
TRIG:TIM2:START:SECONDS <current time> + 60
To configure timer 2 for an alarm to fire 1 minute
from now and output a pulse on digital I/O line 3,
query to get the current time. Add 60 seconds to
that value and use that to configure the start
seconds. Enable the timer.
Example 2
DIG:LINE5:MODE TRIG,OUT
TRIG:DIG5:OUT:STIM TIM3
TRIG:TIM3:DEL 3e-3
TRIG:TIM3:COUNT 5
Configure timer 3 to generate 5 pulses on digital
I/O line 5 that are 3 ms apart.
Example 3
DIG:LINE3:MODE TRIG,IN
DIG:LINE5:MODE TRIG,OUT
TRIG:DIG5:OUT:STIM TIM3
TRIG:TIM3:DEL 3e-3
TRIG:TIM3:COUNT 5
TRIG:TIM3:START:STIM DIG3
Configure timer 3 to generate 5 pulses on digital
I/O line 5 that are 3 ms apart when a digital input
is detected on digital line 3.
