I THINK
1} with scalers {using some form of attneuator T pad for rf shunt for dc ac}
a decade resisistance box is handy !!!!
you can measure voltages outwith the soundcards range of inputs
and via versa
any soundcard outputs /inputs from its analogue ports
for input 1v p-p line in {peek to peek } for ac
so /.707 to get max dc value
or the mike input is good past this by a factore of 10db - 50db
dependant on the card and how the applet sets it up
most sb cards and codecs even ac97 onboard types
conform to sb 16 bit standard or above
and all have a mike amp also
{from the ones ive used in the past}
for ouput well some soundcards give far more watts of waveform than others some even are hifi amp levels in exess of 15 watts per channel
so high voltage with this type of card is to be respected
any level above 1v p-p audio line level input will blow it up or atleast try to damage it
i recomend that you not only run the software you downloaded
but again read the docs as i see this is mentioned
if you get stuck with translations
its best to type into google the word in questions
for a better explinations {not to insult you sorry}
or use babblefish
http://babelfish.altavista.com/ its the best one online
to translate
some pals tell me its best to try english to a closer language then to native
to get better effectors to your own language
but this is a basic question of level convertion in voltage and current
and how YOU choose to limit both
as for frequency range's
this is around ~ 1hz - 15khz audio ranges
look to the specs for the front end and back end of your card
if its a sblive or audigi use the
www.come.to/sblive drivers
they are better for this type of use
but dont expect to then play games with eax and fancy creative native stuff
raw and fast is best for eda machine for study
and keep to this
avoid then complex games in your machine unless they are simple or 8 bit etc sims
