Serial Pattern Trigger (R&S
RTH-K19)
The serial pattern event is used to trigger on signals with serial data patterns in relation
to a clock signal - for example, on bus signals like the I²C bus. The trigger occurs dur-
ing the reception of the last bit of the defined pattern.
3.6.12.1
Pattern Definition
The pattern defines the bits of the serial data to be found in the data stream.
The pattern definition described here is for the serial pattern trigger; however, a very
similar pattern editor is available for other functions, such as protocol-specific triggers.
When you tap the pattern field, a pattern editor is displayed. The current bit definition in
binary and hexadecimal format is displayed at the top of the editor, a virtual keypad is
displayed beneath it. To define a bit, select the bit in the displayed pattern, then select
the bit value from the displayed keypad. The currently selected bit is indicated by a
blue background.
