The operations are organized in Digital to Analog, Timing, and Other columns on the pop-up for
convenience.
Choose the desired operation for your decode output by clicking the large icons on the pop-up.
Note: When accessing these parameters from the Measure button, the measurement source defaults to
DecodeX. Measurements also can be accessed using the standard Measure → Measure Setup... and Measure
dialogs. When accessed using the latter method, DecodeX has to be deliberately set as the source - instead of
the standard Signal, Math, Memory, or other trace (C1, F1, M1, etc.).
Decode Output Operation Detail
The following decode output operation explanations are organized into Digital to Analog, Timing, and Other
sections to coincide with the pop-up.
D IGITAL TO A NALOG D ECODE O UTPUT O PERATIONS

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.
T IMING D ECODE O UTPUT O PERATIONS

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).
O THER D ECODE O UTPUT O PERATIONS

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.
Decode Measurement Parameters via Measure Setup
TIP: You can also access these same Decode Measurement parameters from Measure → Measure Setup... on
the menu bar.
After selecting a given Px measurement from the main Measure dialog, additional settings can be made to the
corresponding dialog as follows:
