Is anybody in this world wishing to use or even manufacture the ultimate
distortion measurement equipment? If yes, please go to
http://www.amplifier.cd and read in its Test Equipment directory
about VK-1 audio oscillator and VK-2 distortion meter.
With this set you can confidently measure total harmonic distortion (THD)
as low as 0,0002% within 20Hz-20kHz, but if this limit seems too high, just add an ordinary PC (with SpectraLab 4.32 software installed) and you will observe on the monitor the separated harmonics of distortion down to -145dB.
Important features of these instruments are also their portability, simplicity
of use and very reasonable expected price, that can make them accessible
both to electronics professionals and audio enthusiasts.
The only problem which remains is to find a suitable manufacturer for these instruments. Any advices on that matter will be accepted with thanks.
