3. Touch any measurement operation to select it. Options are:

View Serial Encoded Data as Analog Waveform - Automatically sets up a Message to Value
parameter and then tracks the assigned measurement. In doing so, a Digital-to-Analog
Conversion (DAC) of the embedded digital data is performed and the digital data is displayed
as an analog waveform.

Message to Value - Extract and convert a specific portion of the data/payload in the message
and display it as an analog value.

MsgToAnalog (Message to Analog) - Computes the time difference from a protocol message
to the crossing of a threshold on an analog signal.

AnalogToMsg (Analog to Message) - Computes the time difference from the crossing of a
threshold on an analog signal to a protocol message.

MsgToMsg (Message to Message) - Computes the time difference from one protocol
message to another protocol message.

DeltaMsg (Delta Message) - Computes the time difference between two messages on a single
decoded line.

Time@Msg (Time at Message) - Time from trigger to each protocol message (meeting
specified conditions).

BusLoad - Computes the load of user-defined messages on the bus (as a percent).

MsgBitrate - Computes the bitrate of user-specified messages on decoded traces.

NumMessages (Number of Messages) - Computes the number of messages which match a
user-specified definition in decoded traces.
4. On the next dialog, choose a parameter location (P1-Px) in which to run the measurement.
NOTE: If you choose a location that already stores a measurement, this selection will overwrite that
setup.
From the Decode Setup Dialog
You can also access the Select Operation... dialog of serial data measurements by touching the Measure
button on the Decode Setup dialog. Follow Steps 3 and 4 above to set up the measurements.
Measurements are set on the source of whichever Decoder (1-4) is currently selected on the Decode
Setup dialog.
From the Measure Menu
The full menu of available measurements can be accessed through the menu bar. Choose Measure >
Measure Setup and follow the usual procedures for setting up a measurement. In this case, you will
have to manually choose the source to measure.
