Trigger Configuration

The new Trigger Configuration Screen introduces a dual-mode (GUI and text), schematic-like approach to configuring the matches, sequencers and trigger output from a single window. A text window shows the 'formula' for the configuration while the 'schematic' shows the flow. These two sections update together to provide two distinct views of the configuration. Multiple trigger configurations can also be selected and created using the selection area in the upper left corner of this screen.

Trigger Configuration Selection

Multiple trigger configurations can be created and stored in the DigiView Data File. Use the selection box to quickly chose another trigger

configuration. After making a selection, click the "apply" button on the bottom of the screen for the changes to take affect. To create, copy or rename a configuration, use the icon to the left of the selection box to open the Trigger Selection Editor.

Trigger Formula (left portion of screen)

The formula presents a summary of the complete configuration. Since this summary can be quite involved with a complex trigger condition, each section will "highlight" as items in the graphical section are selected or the mouse moves over them. The formula will automatically scroll to bring the highlighted section into view while working in the graphical area of the configuration. In the image above, the summary of "MATCH 2" is brought into view as Match 2 is selected (shown in blue below).

Schematic (right portion of screen)

This area is where the actual configuration is accomplished.

Every trigger configuration starts with a match condition and ends with Trigger Out, so the work flow is designed from left to right, starting with the Match Types (see: Match Types).

When the very first Match type is selected and the match condition has been specified, the match will automatically be routed graphically to the Trigger Out. For the DV3 series, this means it will route to TERMS 1, then the NON-Sequenced option and then to Trigger Out. This automatic function is only performed if no other connections already exist. Once you have started making connections for your trigger configuration, the software will not try to "guess" your intentions. Since this would hinder your work and cause aggravation, the software allows you to manually connect or disconnect if the action is valid. Only the obvious connect and disconnects will be performed automatically.

NOTE: The graphical connections in the trigger configuration directly correspond to the physical circuit connections in the hardware, making this screen an overview of the resulting logic in the analyzer's hardware.
