6.3.13 Serial pattern
Access: "Menu" > "Trigger" > "Setup" tab > "Type = Serial Pattern"
The serial pattern 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 instrument expects the bits coming in LSB first order
. A triggered waveform in the
diagram shows the LSB on the left and the MSB on the right side.
For convenient and comprehensive triggering on specific serial data, options for serial
protocol analysis are provided.
If option R&S
RTO6--K13 is installed, you can use the recovered clock signal for the
serial pattern trigger instead of a real clock signal, see Chapter 18.3.2.3, "Serial pattern
trigger using CDR", on page 1119.
Data level
Sets the voltage level for the data signal.
If the signal value is higher than the data level, the state is 1. Below the level, the sig-
nal state is 0.
