PRE TRIGGER DELAY
Alternatively, a negative trigger delay value may be specified up to the maximum time window depth of
the acquisition window. The value may be entered directly from the keyboard or using the knob. The
following time interval range is available:
128 msec to 1280 msec.
This situation is shown in Figure 5-27. The example shows a similar scenario as before, only this time the
trigger delay was set a -20 ms. Notice that the data acquisition window now contains data that occurred
before the user pressed the ENTER key to start the acquisition.
