Triggers
DigiView User's Guide
You can define a TRIGGER condition. When the hardware detects this condition, it will
'TRIGGER' the logic analyzer. When the sample buffer fills (or you manually STOP it), the data is
transferred to the PC. The software on the PC then displays the data to you.
The trigger point is centered on the screen and is always TIME 0. All data prior to the trigger is
negative time and all data after the trigger is positive time. If you stop the analyzer before a
trigger condition is detected, the approximate center of the collected sample buffer is considered
the trigger and the end of the data is the point where the hardware sampling was manually
stopped.
In this version, the triggers are specified in terms of SIGNALS. After assigning channels to
signal names ( see: Signals), you can configure the trigger condition based on the defined signals.
Most engineers will find it easier to reference the condition as it relates to the circuit's function
rather than remembering which channels of the analyzer were used to connect to specific signals
in the circuit.
DigiView's new trigger configuration screen centers the user's focus on function; making it much
easier to quickly analyze and modify a very complex trigger condition. The following graphic is an
example of an advanced trigger condition for the DV3xxx series.
(see:
Example of an Advanced Trigger Configuration for DV3400:
Reset Colors - This button will reset the colors for this signal so that they will match the
CLK - Select a channel to decode as a CLOCK to qualify the Data channel.
Data - Select a channel to decode as the DATA.
Enable - Select a channel to Qualify the CLOCK.
