    Improvised Alternatives to a High Voltage Probe for Oscilloscope

    I built a 20cm square plate capacitor using aluminum foil and an office laminating machine. It is being charged with a 20KVAC square wave from a modified domestic ion generator, which is a low current source. I would like to connect an oscilloscope across the plates to observe the waveform of...

    Wi-Fi Beacon Photo or Plot?

    Can anyone provide an oscilloscope screenshot, or plotted output, that clearly shows several cycles of the 10Hz beacon as embedded within a Wi-Fi transmission?

    Analog Circuit to Randomly Modulate Amplitude and Frequency

    I have a 20Hz 2Vpp sine wave and would like to simultaneously randomize both its amplitude and frequency (or phase) within a manually adjustable range of 10-50% deviation. For example, the original signal would be made to randomly swing between 2Vpp and 0.2 to 1Vpp (adjustable), with a...
