Is it really oscilloscope?

  1. Jul 30, 2011 #1
    Hello! One project I want to work on is an embedded systems project which I can measure voltage (both positive and negative) and plot it on a graph where the x axis is time and the y axis is voltage. Would this be considered an oscilloscope or would it be something else?

    Also, I was thinking in order to measure negative voltage, I was thinking of applying a negative voltage to the cathode of a diode so that it conducts when negative voltage is applied then let the negative voltage go through an inverting amplifier so the mcu can measure the "negative voltage." (I know I have to consider things like bandwidth, and the fact that omp amps have a low pass response, but I'm saying hypothetically)

    An oscilloscope uses a time base that makes a periodic signal seem as a static picture. This is not what you had described.
