La familia crece

oscilos

Mi autoregalo de reyes. Un Hitachi V-212 de segunda mano en perfectas condiciones. No podía esperar, lo puse encima de la cama y le inyecté una señal cuadrada con el arduino (un pulso de 50Hz, 10ms alto y 10ms bajo), lo ajusté, y perfecto :-)

Ya tenía ganas de uno, he estado haciendo unas pruebas con él, como comparando el sonido de los diferentes modelos de gameboy, y se nota bastante la diferencia entre ellas. En el foro he actualizado la entrada con una comparativa.

  1. Hmm, I think the probe needs some adjustment. Look at the big slope at the edges of the curve. (Zoom in to see it better.) There’s (probably) a screw on the top that will let you adjust the capacitance compensation for the cable. Try to get the edges as close to 90 degrees as you can. But beware that unless you’re using a plastic screwdriver, the screwdriver and your body will work like a capacitor and shape will change once you let go of te screw.

    You should also probably use the builtin calibration source when doing this. (Attach the probe to the hook just to the left of the coax input for channel 1)

    Calibrating your probe, of course matters more when doing digital/other high frequency stuff than when analysing musical signals.

  2. Tnks nitro, I think that probe is not in good shape, I tried to adjust it, but I always get curved edges. I bought another probe, and the new one works perfect once it has been adjusted, perfect square signal.
    Anyways thanks for the tip :-)
