trigger.timer[N].delay
This attribute sets and reads the timer delay.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Instrument reset
Recall setup
Trigger timer N reset
Not saved
10e-6 (10 μs)
Usage
interval = trigger.timer[N].delay
trigger.timer[N].delay = interval
interval
Delay interval in seconds
N
Trigger timer number (1 to 8)
Details
Each time the timer is triggered, it uses this delay period.
Assigning a value to this attribute is equivalent to:
trigger.timer[N].delaylist = {interval}
This creates a delay list of one value.
Reading this attribute returns the delay interval that will be used the next time the timer is triggered.
Example
trigger.timer[1].delay = 50e-6
Set the trigger timer 1 to delay for
50 µs.
Also see
trigger.timer[N].reset() (on page 7-341)
trigger.timer[N].delaylist
This attribute sets an array of timer intervals.
Type
TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Instrument reset
Recall setup
Trigger timer N reset
Not saved {10e-6}
Usage
intervals = trigger.timer[N].delaylist
trigger.timer[N].delaylist = intervals
intervals
Table of delay intervals in seconds
N
Trigger timer number (1 to 8)
Details
Each time the timer is triggered, it uses the next delay period from the array. The default value is an array with
one value of 10 μs.
After all elements in the array have been used, the delays restart at the beginning of the list.
If the array contains more than one element, the average of the delay intervals in the list must be ≥ 50 µs.
