yes i understand clearly what yo mean and i will get you the scope pics but there is a small issue and it is that i use a pc scope software called visual analyzer 2011 version and i caliberated it by inputing acurate 1VAC into my sound card input so as to be able to measure wave forms in volts and peak voltages so i dont know if you know about this software and how to read the scale.
for example the bubba sine wave reads 50hz with peak to peak voltage 0.9V powered fron a 12V lead acid battery and now considering the calibration using 1V which is the maximum a sound card can take so as not to damage it,how do you then get the actual peak to peak in terms of DC.
i dont knoe if you get what am trying to say but i will get you the scope pics asap.thanks so far
Hello,
You mean the scope isnt a real scope but a sound card 'scope' ?
That might not help us at all here because we need to see DC levels.
