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:
Serial Decode License See:
DSOX4AUTO — you can decode CAN
(Controller Area Network) and LIN (Local
Interconnect Network) serial buses. • "CAN Serial Decode" on page 391.
