3-29. Tn (Trigger Mode Commands)
The Trigger Mode commands duplicate the front panel EX TRIG button. In addition, the
commands can enable or disable the rear panel trigger and the automatic settling time
delay.
Figure 3-7 illustrates how to select among the five types of triggers: continuous trigger,
front panel trigger, rear panel trigger, and two bus triggers. Note that the front panel
TRIG button is enabled only while the instrument is under local control.

In the continuous trigger mode (T0), triggers are initiated at the selected reading rate.
Each new reading is loaded into the output buffer as it becomes available, unless the
instrument is busy sending previous output data.
