Re: Diy oscilloscope #parts
My cloud of dots would be a silly way to try and see an RF signal's envelope.toggle quoted messageShow quoted text
Instead, spend $0.10 on a diode, resistor and a cap or two for an RF probe (or AM detector).
The RC low pass filter should have a corner freq of 100khz instead of 1Hz,
as we will be watching the output with a DSO138 instead of a DVM.
That's probably more what Dexter had in mind when he suggested
watching RF envelopes with the DSO138.

Could see Dexter's modulation envelope on sub 1mhz RF as a cloud of dots,
