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
Agilent'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 DSOX3AUTO license, you can decode CAN (Controller Area
Network) and LIN (Local Interconnect Network) serial buses. See:
• "CAN Serial Decode" on page 339.
• "LIN Serial Decode" on page 347.
• With the DSOX3FLEX license, you can decode FlexRay serial buses. See
"FlexRay Serial Decode" on page 355.
