Description: The Silver DSO Quad is an open-source pocket-sized 4-channel digital oscilloscope. It's based on the ARM cortex M3 32-bit platform, providing 72MS/s sampling rate with integrated FPGA and high speed ADC. The Internal 2MB memory can even store waveforms in various formats which you can transfer to your computer using a mini-USB cable.

  • The link to the Product Video, shown in the main listing for this product, goes to a page which says “This video has been removed by the user”. The video link needs fixing.

  • The analog bandwidth is not listed, not even in the Wiki. Based on an analysis of the circuit, the analog channels are 4.4MHz -3dB bandwidth. In addition, there are a lot of these scopes out there with an incorrectly specified TVS protection diode on the digital channels that limits their bandwidth to under 1MHz.

    Also, this is NOT 72Msps per channel, It is dual 36Msps ADC converters.

    Nyquist has nothing to say about bandwidth of a scope. Clearly, you cannot represent a sine wave with only two samples. It takes more like 8 or 10. That fits with a 4.4MHz bandwidth with 36Msps.

    In addition, square waves require at least the 5th harmonic to approximate, more like 9th harmonic if you want any reasonable representation of the rise time. One of the requirements of a square wave is rise time. The rise time of the scope must be several times faster (shorter) than the rise time of the square wave, or it affects how the actual rise time is displayed.

    There is another requirement with square waves: You are often using a scope on them to look for glitches, overshoot, and ringing. Those things will have a spectral bandwidth many times greater than that of the square wave. For that, the two digital channels are useless.

    I consider a 4.4MHz scope barely adequate for audio work and sub100kHz digital signals.

    The function generator is primitive. Sine, triangle, and sawtooth waveforms look like they are generated from only 3 or 4 bits of information, with big noisy steps between levels. They are stairstepped, is what I’m saying.
