Explanation
This function triggers on serial pattern signals.
Data, Clock, CS, and Latch Sources
You can select the data, clock, CS, and latch sources from CH1 to CH4.
Clock
• Clock ON/OFF
You can select whether or not to sample the data source in sync with the selected
clock source.
ON
Samples in sync with the clock source.
OFF Does not synchronize to the clock source.
• Sampling Timing
You can select the clock edge that specifies when the data patterns are sampled.
On the rising edge
On the falling edge
Data Pattern
You can use a data pattern as a trigger condition. The data pattern trigger condition is
met when the specified pattern matches the sampled data source pattern.
• You can set a pattern consisting of up to 128 bits. Set the pattern 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 “$.”
