16th April - Lancashire County Cricket Ground- Emirates Old Trafford, Talbot Road, Manchester

18th April - Reading Football Club, Reading, Berkshire, RG2 0FL

Anglia, partnering with Analog Devices are offering two in depth, technical workshops on signal conditioning.
 

The workshops will focus on the exploration of the signal chain and techniques to quantify noise. It will also include the examination of the signal conditioning of the analog /digital converters, along with bit resolution, speed, the reference voltage, optimization of resolution and filters.

Additionally, a technical dive into the Op Amp, including the structure and choice of components, influences, disruptive factors, suggestions for improving the signal chain, tools and circuit suggestions, along with practical tips.

For the hands-on session, an ADALM2000 Active Learning Module will be used (which will require all attendees to bring a laptop that requires installed driver for ADALM2000).

All attendees will take away an ADALM2000 Free of Charge!

The ADALM2000 works as a portable lab that, when used with a host PC, can augment classroom learning. Analog Devices’ Scopy software package supports the ADALM2000 and provides an intuitive graphical user interface (GUI) so users can learn faster, work smarter, and explore more. Built on open-source technology, Scopy can be examined and extended by anyone.
Scopy uses the features of the ADALM2000 to create,

• Voltmeters
• Digital oscilloscopes
• Spectrum analysers
• Power supplies
• Function generators
• Arbitrary waveform generators
• 2-port network analysers
• Digital logic analysers with bus analysers
• Digital pattern generators
• Digital static inputs/outputs

• What types of noise exist
• Noise in resistors, transistors, amplifiers
• How to compute the total noise
• How to estimate noise in amplifier circuits
• Comparison of theoretical analysis with simulations

Theory Part 2: A/D Convertors - Precision Signal Chain

• Introduction to Signal Chains

Hands-on Workshop: 0.1Hz to 10 Hz Demo
In the demo attendees are going to estimate the 0.1 Hz to 10 Hz noise for three different amplifiers from the datasheets:

• LT1782 – a low power op amp
• ADA4077 – a low noise op amp
• ADA4522 – a low noise, zero-drift op amp

The workshop will include,

Using the information provided to estimate the noise from the data sheet.
Use the ADALM2000 + demo board to measure the noise.
Compare our measured results to our estimated results.
Use the Network Analyzer feature of the ADALM2000 to measure the filter response from 1 Hz to 100 Hz.
Signal Chain Designer Demo and conclude with simulating the circuit on Signal Chain Designer and compare the results.
