Default Audio Frequency and Phase Response

In August we announced the Open Instrumentation Project (OIP), which
supports open-source software and low cost hardware for electronic
instrumentation.

One of the instruments is a VNA (vector network analyser) that measures
amplitude and phase response over the frequency range 0.1Hz to 100kHz. The
VNA is available as Open Software, working with the Syscomp DSO-101
oscilloscope and WGM-101 waveform generator.

The mechanics of the VNA are described in an article in the September issue
of Circuit Cellar, titled 'Programmable Network Analyser'.

Further detail is available in the paper 'A Software-Based Network Analyser'
at the Papers section of the Syscomp web page:

www.syscompdesign.com/tech.htm

Another paper 'Audio Measurements with a Network Analyser' describes audio
applications of the VNA and is available from the same web page.

Screen shots and the software for these instruments are available from
sourceforge at:

http://sourceforge.net/projects/oip/

The software is licensed under the GPL.

The oscilloscope and waveform generator are described on the Syscomp web
page at
