morieris Posted June 24, 2017 Share Posted June 24, 2017 As already mentioned in your FAQ, there are some issues with noise/peaks on the oscilloscope channels of the OpenScope. In the example (OpenScope_Peaks.png) you can see distortions of up to 200mVpp. The test setup: Ch1: connected to DC1 @ 157mV Ch2: shorted to GND OpenScope is powered by a 5V USB power bank I noticed, that the distortions can be completely eliminated by touching the PCB antenna of the MRF24. It seems to work equally well if you tape down one of the insulated ground wires onto the PCB antenna. or keep protective earth close to the outer edge of the PCB antenna (e.g. between two layers of insulating tape).
