Configuration
27
Set to 0 to disable.
Frame Idle Timeout (0 to disable)
A new frame is started if no new bits are seen for more than the specified time. Set to 0 to
disable. This can be useful if there are no sync lines or field counts but you can see a
consistent pause before each frame starts.
Frame on SS
Specifies that we should terminate a frame on SS disable edges and start a new frame on
SS active edges.
Display Fields
MOSI-MISO
Field type used to show normal data.
Shows the both data channels, separated by a colon: ' MOSI : MISO '
(P)MOSI-MISO
Field type used to show partial (interrupted) data fields.
Shows '(P)' followed by both data channels, separated by a colon: ' (P)MOSI : MISO '.
NOTE: Multiple framing methods can be used at the same time. For example, you could use a
frame length specifier and the frames will be broken into the specified lengths. If a timeout is
specified, it will override and terminate a frame if the specified time is exceeded.
Reset Colors - This button will reset the colors for this signal so that they will match the currently
selected color theme (see: Color Themes 55 ).
2.3.2
Triggers
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 our DigiView Software, triggers are specified in terms of SIGNALS. After assigning
channels to signal names ( see: Signals 8 ), 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 DV3 series.
