From an idea in 2002 to Version 26
A concise timeline. Dates and milestones will continue to be refined from the historical archive.
The project begins
Development starts with the idea of using a PC sound card as a flexible measurement platform.
Early public versions and articles
VA grows into an integrated oscilloscope, spectrum analyser and generator; the first technical articles introduce it to a wider audience.
Dedicated hardware and ZRLC
The Nuova Elettronica interface and the ZRLC work extend VA from audio analysis to component and impedance measurements.
Scientific publications
IMEKO and Elsevier publications document virtual instrumentation and uncertainty-aware measurement methods.
Continuous evolution
New measurement, recording, filtering and analysis functions are added while compatibility with modern Windows systems is maintained.
The Silvia editions and Version 26
A renewed interface, 32/64-bit builds, modern audio APIs, advanced response measurements and many internal improvements mark the latest generation.
