My hantek 6022 USB oscilloscope doesn't have AC coupling, which makes it "impossible" to measure the output ripple of the DC-DC converters that I will be building on the breadboard (breadboarding a DC-DC converter isn't a good idea, but i can't solder 5 different circuits!). In order to measure output ripple, I need to "add" an AC coupling feature to my scope. This I will do by using the high pass filter shown above. The cutoff frequency for the above filter is 1.6KHz, so it should be fine to measure 100KHz and 150KHz ripples. If anybody has any suggestions on how to make it better, please let me know. The 10meg resistor is the input impedance of the probes.
