Triggers:Ref:Pattern Match:Pattern

Short Name: RefTrig.PatMatch.Pattern

Sets the pattern match mask for the Reference trigger. This property is used when Reference Trigger Type is set to Pattern match.

The pattern is a string of characters representing the entire pattern to match. Each character corresponds to a particular channel.

• X or x: Ignore the channel
• 1: Match on a logic 1
• 0: Match on a logic 0
• R or r: Match on a rising edge
• F or f: Match on a falling edge
• E or e: Match on either edge
• Spaces are ignored, and are useful for readability to segment long patterns

The rightmost character in the expression corresponds to the lowest numbered physical channel. For example, XXXX XXXX XXXX 1111 1100 specifies to match when channels 0 and 1 are 0 and channels 2-7 are 1.

The values seen by pattern matching are affected by the Data Interpretation property.
