Digital channels and serial decode cannot be on at the same time. The [Serial] key
takes precedence over the [Digital] key. Serial triggers can be used when digital
channels are on.
Triggering on
Serial Data
In some cases, such as 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
[Mode/Coupling] 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 [Serial] key, then the Signals softkey.
Serial Decode Options
Keysight's hardware-accelerated serial decode options can be installed when the
oscilloscope is manufactured, or added later. The following serial decode licenses
are available:
• With the DSOX2AUTO license, you can decode CAN (Controller Area Network)
and LIN (Local Interconnect Network) serial buses. See:
• “CAN Serial Decode" on page 305.
• “LIN Serial Decode" on page 312.
