Oscilloscope uses your PC...Any reviews?

[kyanczer]

I want to read ac harmonic levels ..Any experience using the O-scope that uses the sound card in your PC to display various data?

its fine , but the thing is that you cant measure voltages above a volt or so , or you will
end upp frying your pc's soundcard , also the frequency is limited to 44 KHZ

I bought an old Textronic scope 465B with a bandwidth of 100Mhz for about £120 a few years ago. Does everything I want for less than the cost of a phone or decent audio amp. Would this be a good solution? Spend your time making the harmonic measurements you want rather than trying to get your PC working as a scope.

Just realised the date of the OP. Oh well. Mention of "sound card" should have given it away!
