Data Acquisition Systems (DAQ): Signal Conditioning, Graphical Programming and Test Automation – Dubai, 16–20 Nov 2026

Programme overview

Introduction:

Data acquisition systems sit between a physical test and every decision taken from its results, yet many rigs log aliased waveforms, unbalanced bridge readings or unlabelled files that nobody can trace back to a sensor. This Core Concept course takes test, laboratory and R&D engineers through the full DAQ chain: transducers, signal conditioning, analogue-to-digital conversion, sampling, graphical dataflow programming, instrument control, data logging, signal analysis and chain validation. Participants produce a DAQ and Test Automation Application Design for a case test rig, ready to build and verify.

Course Objectives:

• Specify a DAQ chain from transducer to host software against channel count, bandwidth, range and accuracy requirements
• Configure amplification, bridge completion, isolation and anti-aliasing filtering so each channel reaches the ADC within its input range
• Select sample rate, resolution and acquisition mode that capture the signal without aliasing or wasted storage
• Build acquisition and test sequencing code with graphical dataflow programming, loops, arrays and state machines
• Automate bench instruments over serial and bus interfaces and log results in traceable file formats
• Validate and calibrate a DAQ chain and analyse acquired waveforms with FFT and digital filtering

Target Audience:

• Engineers responsible for designing and running mechanical, electrical and environmental test rigs
• Laboratory engineers responsible for measurement set-ups, bench instruments and results records
• Instrumentation engineers responsible for sensor wiring, signal conditioning and channel checks on test benches
• R&D engineers responsible for prototype characterisation and experiment data capture
• Test engineers responsible for automating repetitive product and component tests

Course Outline:

• Application State Diagram, Error Handling and Operator Front Panel Layout
• Logging Scheme, Automated Test Report Generation and Pass-Fail Limits
• DAQ and Test Automation Application Design Review and Peer Challenge

Skills You Will Gain:

• Transducer Selection
• Bridge Circuit Configuration
• Anti-Aliasing Filter Design
• Dataflow Programming
• Acquisition Task Configuration
• Bench Instrument Automation
• Test Data Logging
• Spectral Analysis

Why Attend This Course:

• Return with a DAQ and Test Automation Application Design for a case test rig, covering channel map, code structure and logging scheme
• Stop losing test runs to aliasing, clipped channels and unbalanced bridges by setting conditioning and sample rate from the signal itself
• Replace manual bench readings with automated instrument sequences that write labelled, traceable result files
• Compare rig and laboratory practice with engineers from automotive, aerospace, energy, electronics and research settings

Conclusion:

A test result is only as sound as the DAQ chain behind it: the transducer, its conditioning, the sample rate, the code that sequences the test and the file that records it. The course moves from chain architecture and transducer choice through bridge circuits, isolation, sampling and conversion, into graphical dataflow programming, counters and digital I/O, then instrument control, logging, spectral analysis and chain validation. The final day turns this into a DAQ and Test Automation Application Design for a case test rig.
