0 attila Posted March 22, 2023 Share Posted March 22, 2023 Hi @bherd Notice the warning on the screen: You are using a capture of 32k samples at 80MHz, 0.4ms in total, and are decoding this as 1kHz Manchester. Specify the signal bit rate for the interpreter and adjust the capture rate accordingly, at least 4x the bit rate. Link to comment Share on other sites More sharing options...
0 bherd Posted March 23, 2023 Author Share Posted March 23, 2023 Hi thanks for the response! Actually I have Manchester set for 300khz, time base now set to 2ns/div rate 800mhz and still no trigger. Link to comment Share on other sites More sharing options...
0 attila Posted March 23, 2023 Share Posted March 23, 2023 Hi @bherd Could you attach or send me a workspace or project with captured data ? Link to comment Share on other sites More sharing options...

0 attila Posted March 27, 2023 Share Posted March 27, 2023 Hi @bherd These do not seem to be valid codes. I see pulses of 2.5-40ns, which could indicate 200-25MHz signaling, far away from 300kHz. Is the voltage level/logic threshold ok ? This can be adjusted in the Supplies tool. Link to comment Share on other sites More sharing options...
