So the probe points for the TX and RX are TX and ground on one probe and RX and ground on the other? And for the single pin communication you're getting clock and ground and the other probe has that single pin and ground?
Back a long time ago.... During Space Lab testing with the Shuttle program, I was involved with designing, proto-typing, testing, and implementing interface circuitry for use in the PPCU residing in the O&C High-bay. O-scope operation was easy as breathing and the transmission/receiving of data signals used the differential mode almost exclusively for its low noise characteristic. The following method just jumped right back into my head - INVERT one channel, ADD both channels, = your differential measurement.. ;-) You're welcome....
I would like to see a Futaba SBus signal compared to a FrSky "inverted SBus" signal on the 'scope. I mentioned your other video in various RC forums and got dissed for not being a "true believer".
Very usefull review. Thank you very much.
Glad it was helpful!
I believe the odd pulse on the clock is the break between address and data.
Can the data be saved in memory as so that a few lines of data can be displayed?
The serial data is not inverted. The idle state is "1", with a start-bit signaling the start of a character dropping down to zero for one bit time.

Hi, Very informative videos. I have off the topic question here. how to measure differential pair signal?

@@ainttakenanyshit ¡Thank you!

@@ainttakenanyshit 🙂 Thank you for the information regarding differential measurements. God Bless.

How much bandwith each channel can be measured?
Rigol DS1202ZE Oscilloscope - Drone UART & I2C Signal Tested
Is it possible to write decoded signal to usb and analyze the messages on computer? Like what does hex mean
yes, it is possible, look for event table in the manual - see on the rigol website for the free available documentation
Glitch in the matrix starting at 20:04.
Hahah I missed that one.
thanks skipping over the part on how to get to the decoding function on the scope
