With Custom Tools
You Can:
Enhance How Data is Displayed
• Color-code specific states of your
trace.
• Display some of your trace data in
engineering units.
• Convert the raw trace of a propri-
etary bus to a transaction-level
trace of that bus.
Manipulate Data
• Unravel interleaved data into two
or more columns of data.
• Combine the traces of two differ-
ent analyzers into one trace, with
each column being combined or
separately displayed as prescribed
by you.
• Modify your scope trace using an
algorithm developed by you, such
as an analog filter, beat frequency,
or DSP algorithm.
Read or Write External Files
• Accumulate information from
repetitive traces taken by the
analyzer in a file on your PC or
UNIX workstation.
• Write specific types of states or
trace data that have been analyzed
to an Excel consumable ASCII file
on your PC or UNIX workstation.
• Use information read from a file
on your PC or UNIX workstation
to modify the display of an
analyzer trace.
Custom Tool Examples,
Added Text in Trace
This example shows how a custom
tool can convert data to text to
present information in a form that
is much easier to understand than
the raw data.
The original trace comes from a
control unit in an automobile.
Embedded in the data is informa-
tion about the engine and trans-
mission. When MODE = 0, DATA
represents engine information,
including RPM, fuel level, fuel to
air ratio, and manifold pressure.
When MODE = 1, DATA repre-
sents transmission information,
including gear position and
temperature.
This custom tool allows the
user to specify Fahrenheit or
Centigrade for the engine
temperature data.
