ASCII Overview and Commands
TRIGGER:DELAY:ACTUAL?
Returns the actual trigger delay from the most recent trigger event.
Query Syntax:
TRIGGER:DELAY:ACTUAL?
Example Statements:
OUTPUT 70924;"trigger:delay:actual?
ENTER 70924;Result$
Parameter Definitions:
Result$ contains the returned actual delay from the most recent trigger event and
the resulting first output sample time. This delay value provides more accuracy than
the delay parameter alone since it includes a measurement of the fractional part of
the output sample period between the actual trigger event and the next available
output sample. The trigger delay accuracy improves to one ADC sample clock period
rather than one output sample period. This can result in a substantial improvement
in accuracy when narrow bandwidth decimation filtering is used. The this command
must be sent for each new trigger event that requires precise delay measurement.
The actual delay is still expressed in output sample periods, however, it can take on
non-integer values.
