    Now, I’m looking at the DSO nano V2 oscilloscope.
    http://www.seeedstudio.com/depot/dso-na … ?cPath=174

    Is this oscilloscope capable for MPX Tilt correction and Flatten the respond (PEQ adjust) ?
    If yes, another concern is the accuracy of the scope, would it be accurate as normal oscilloscope ?

    If it’s not suitable for calibrating BBP, what are you recommend ? just use for BBP only.

    Thanks.

    I think that could be suitable because its analog bandwidth is 200KHz, and input is DC coupled.. Also max. samplerate is 1 MHz…

    But I would also recommend the DSO Quad, it’s a lot more capable plus it’s not that expensive, $199..

    From having seldom worked with an oscilloscope, I wouldn’t mind seeing an illustration showing how an oscilloscope is hooked up to BBP and the transmitter.

    Yes, I’d like to see too.

    In my imagination, i would hook it up at the RCA connector (MPX output),
    or may be at the sound card circuit (pin of female RCA connector) while loading.

    Is this OK ❓

    because i don’t want to make Y-Cable.

    A probe for an oscilloscope generally has 1,000,000 Ohms resistance. It’s done so that very very little current flows through the circuit of the scope, to avoid altering the operation of what you’re monitoring, and to allow directly monitoring much higher current circuits that would otherwise be possible.

    If you understood what I Just said, then you would know this basically means you can tap the audio path directly, and that "splitting" it wouldn’t actually be any different than tapping it, other than adding another possible point of failure. 8)

    That being said, it’s important to check the limits for any scope’s capabilities, so you don’t go frying it hooking it up to stuff you shouldn’t. Like the RF outputs of a transmitter. 😉

    I’ve had good luck with BNC T-connectors. No need to make a Y-cable.
