Basic trigger model
The below graphic illustrates the basic trigger model. It provides the fundamental trigger options
needed for many instrument operations.
Figure 77: Basic trigger model
Basic triggering is selected and configured from the BASIC menu item of the CONFIGURE TRIGGER
menu.
Idle
While in the idle state, the instrument cannot perform measurements. The front panel ARM indicator
is off when the instrument is in idle. Pressing
TRIG
takes the instrument out of idle (ARM indicator
turns on).
Trigger mode
With the continuous trigger mode selected, operation continuously loops around the control source to
make measurements (device action). This trigger mode provides continuous reading conversions.
With the one-shot trigger mode selected, operation waits for the selected control source event to
occur before making a measurement (device action). A measurement occurs every time the source
event is detected (see
Control sources
(on page 11-17)).
The trigger mode is selected from the BASIC (MODE) option of the CONFIGURE TRIGGER menu.
