SERIAL TRIGGER AND DECODE OPTIONS
Trigger and Decode
The serial data trigger will quickly iso-
late events on a bus eliminating the
need to set manual triggers and hoping
to catch the right information. Trigger
conditions can be entered in binary or
hexadecimal formats and conditional
trigger capabilities even allow trigger-
ing on a range of different events.
Protocol decoding is shown directly
on the waveform with an intuitive,
color-coded overlay and presented in
binary, hex or ASCII. Decoding on the
HDO4000 is fast even with long mem-
ory and zooming in to the waveform
shows precise byte by byte decoding.
Table and Search
To further simplify the debug process
all decoded data can be displayed in a
table below the waveform grid. Select-
ing an entry in the table with the touch
screen will display just that event.
Additionally, built-in search functional-
ity will nd specic decoded values.
Serial data messages can be quickly
located by searching on address, data
and other attributes specic to a
particular protocol. Once found, the
specic location containing the
specied search criteria can be auto-
matically zoomed to.
