• Data
You can select whether or not to use the data pattern as a trigger condition.
• Comparison Condition
The data trigger condition is met when the result of comparing the input signal
pattern with the specified pattern meets the selected comparison condition.
True
When the patterns match
False
When the patterns don’t match
• Comparison Start Position
In the Pos Mode setting, you can set the comparison start point to the specified
point (Select) or don’t care (X). If you select Select, the DL9000 skips the specified
number of bytes and starts comparing from the next data byte.
Selectable range: 0 to 9999 bytes
• Data Size
Set how many consecutive data bytes you want to compare.
Selectable range: 1 to 4 bytes
• Data Pattern
Set the data pattern for the specified size in hexadecimal or binary notation.
• If you specify X, the condition is assumed to be met regardless of the corresponding bit
status.
• If a binary pattern contains any Xs, the corresponding hexadecimal display will be “$.”
• Example
This example displays the data sequence at the byte level (hexadecimal notation) and
indicates the trigger position. The following notations are used in the figure.
S: Start condition, P: Stop condition, Shading: Compared pattern
