Serial Bus Decode/Trigger
Depending on the oscilloscope model, the following hardware-accelerated serial
decode and trigger options are available:
To determine whether these licenses are installed on your oscilloscope, press

To order serial decode licenses, go to
and search for the
product number (for example, DSOX1AUTO) or contact your local Keysight

Triggering on
Serial Data
When triggering on a slow serial signal (for example, I2C, SPI, CAN, LIN, etc.) it
may be necessary to switch from the Auto trigger mode to the Normal trigger
mode to prevent the oscilloscope from Auto-triggering and stabilize the display.
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 the
[Bus]
key, then the
Signals
softkey.
