Modern vehicles generate enormous amounts of data across communication buses such as CAN, LIN, SENT and FlexRay.
For engineers working on automotive diagnostics, ECU development, sensors, validation or vehicle testing, capturing the communication is often only the first step. The real challenge is finding the particular engineering value hidden inside hundreds or thousands of decoded messages.
TiePie engineering is addressing this challenge with the new Value Extractor I/O in Multi Channel oscilloscope software version 1.49.
The new capability makes it possible to select a specific value from decoded communication data and treat it like a conventional measurement — displaying it as a waveform, meter or table.
In simple terms:
Capture → Decode → Extract → Measure
This can significantly simplify the journey from raw automotive communication data to meaningful engineering information.
From Communication Data to a Measurement
Consider a pressure sensor communicating over a SENT interface.
Traditionally, an engineer may capture and decode the SENT communication and then search through a large table of decoded information to locate the pressure value of interest.
With the new Value Extractor I/O, the workflow becomes much more direct.
Multi Channel captures the electrical signal and decodes the SENT communication. The Value Extractor can then isolate the actual sensor value from that data stream.
That extracted value can be plotted against time just like a conventional oscilloscope measurement.
For example, an engineer can immediately observe how pressure changes when the accelerator is operated or when engine load changes.
Information that was previously buried inside a complex stream of digital messages becomes a clear, measurable engineering signal.

A Powerful Workflow for Automotive Diagnostics and Testing
The Value Extractor works with protocol decoders available within TiePie Multi Channel, including:
CAN | CANopen | J1939 | LIN | SENT | FlexRay | I²C | UART | SPI | DMX512
Specific messages can be selected using parameters such as ID, address and read/write information.
Values can also be converted into the required engineering unit.
This creates an interesting end-to-end measurement workflow:
Electrical Signal → Protocol → Message → Parameter → Measurement
And importantly, these stages can be handled within the same measurement environment.
Why This Matters for Automotive Engineers
Modern automotive systems increasingly combine electronics, sensors, embedded software and digital communication.
An oscilloscope trace can tell you what is happening electrically.
A protocol decoder can tell you what is being communicated.
But the engineering question is often something different:
What is the actual physical value represented by that communication, and how is it changing over time?
It could be pressure.
- Temperature.
- Position.
- Speed.
- Current.
- Torque.
- A sensor reading.
- Or another parameter being exchanged between electronic systems.
The Value Extractor helps bridge the gap between communication data and the physical engineering quantity that the engineer actually wants to investigate.
That makes the capability particularly interesting for automotive diagnostics, ECU development, sensor testing, vehicle validation, troubleshooting and R&D.
Practical Example: SENT Sensor Data
TiePie demonstrates the new capability using an automotive pressure sensor communicating through SENT.
A specific value is selected from the decoded SENT data stream and displayed graphically in real time.
As the accelerator pedal is operated, the corresponding pressure changes become immediately visible on the graph.
Instead of manually examining long tables of measured values, the engineer can directly see the behavior of the parameter being investigated.
Example of a SENT pressure-sensor value extracted and displayed graphically in TiePie Multi Channel.
What Else Is New in Multi Channel 1.49?
Value Extractor I/O is the major new feature, but TiePie Multi Channel version 1.49 also introduces several additional improvements.
These include:
New protocol decoders for LIN, SENT, FlexRay and DMX512
Enhanced filtering of decoded data tables
Improved data recording and file management
High-DPI display support
Various usability and performance improvements

More Than Product Selection — Tell Us What You Are Trying to Measure
Choosing a test and measurement instrument is not always simply a matter of selecting bandwidth or sampling rate.
The right solution depends on what you are actually trying to measure.
How many channels are required?
What signals are involved?
What frequency range needs to be captured?
Do you need protocol decoding?
Are you working with CAN, LIN, SENT or another communication interface?
Do you need long-duration recording?
Do you need signal generation as well as acquisition?
What are you ultimately trying to understand about the system?
This is where Tenet would like to help.
Instead of starting with a product number, you can start with your engineering problem.
