    i'm interestend in this pc based oscilloscope but i'm not sure if this one is rigth for me.

    can u tell me the maximun voltage signal i can measure with this scope?
    the maximun bandwidth i can measure?

    It's not too good for performance. The spec's say 5 volts max for input voltage. The i megaohm input impedance will limit it due to curcuit loading.

    With 15k samples/sec, the fastest signal you might resolve is going to be 7,500 Hz. Using more channels will slow sampling per channel. This is not adequate for audio work, much less logic.

    I don't think this device will be adequate for any realistic needs, other than a classroom demonstrator.

    thanks a lot for your info, will have to continue searching for more options.

    thanks for the link but $500 is really out of my capacity.
