6.3.13 Serial pattern
Access: [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.
Clock source
Selects the input channel of the clock signal.
Remote command:
TRIGger<m>:DATatoclock:CSOurce[:VALue] on page 1183
TRIGger<m>:SPATtern:CSOurce[:VALue] on page 1190
Clock edge
Together with the clock level, the clock edge sets the point in time when the state of the
data signal is checked:
"Positive"
Rising edge, a positive voltage change.
"Negative"
Falling edge, a negative voltage change.
"Both"
Both the rising and the falling edge.
Remote command:
TRIGger<m>:SPATtern:CSOurce:EDGE on page 1191
