6.7.2 Pre-event and Post-event Triggering [3Pi Controller Only]
The range for this offset is:
MX Series I: -104 msec to 1000 msec in single-phase mode or -312 msec to 1000 msec
in three-phase mode (at the highest available sample rates).
MX Series II and RS Series: -42.6 msec to 1000 msec in single-phase mode or –128 msec
to 1000 msec in three-phase mode (at the highest available sample rates).
As shown in the following figure, when the offset is negative, the values at the beginning of
the data record represent samples taken prior to the trigger. When the value is 0, all of the
values are taken after the trigger. Values greater than zero can be used to program a delay
time from the receipt of the trigger until the data points that are entered into the buffer are
valid.
