8 Serial Bus Decode/Trigger
Depending on the oscilloscope model, the following hardware-accelerated serial
decode and trigger features are available:
Triggering on
Serial Data
In some cases, such as when triggering on a slow serial signal (for example, I2C,
SPI, CAN, LIN, etc.), to stabilize the waveform display, it may be necessary to
switch from the Auto trigger mode to the Normal trigger mode to prevent the
oscilloscope from auto-triggering. You can select the trigger mode by pressing the
[Trigger] key, then the Mode softkey.
Also, the threshold voltage level must be set appropriately for each source
channel. The threshold level for each serial signal can be set in the Signals menu
(press [Analyze] > Features , select Serial Bus , then press the Signals softkey).
