DESCRIPTION The TRIG_DELAY command sets the time at

which the trigger is to occur with respect to the

first acquired data point.

This mode is called pre-trigger acquisition, as

data are acquired before the trigger occurs.

Negative trigger delays must be given in

seconds. This mode is called post-trigger

acquisition, as the data are acquired after the

trigger has occurred.

If a value outside the range, the trigger time will

be set to the nearest limit and the VAB bit (bit 2)

will be set in the STB register. The response to

the TRIG_DELAY? query indicates the trigger

time with respect to the first acquired data point.
