Hello, similar problem with I2C :(. 100 kHz clock signal, channel 4: SCL, channel 2: SDA, triggering at channel 1 event: At 2 Ms the oscilloscope is not decoding: a higher sample rate and it decodes properly: |
| tautech:
Wouldn't you normally trigger on the clock ? |

In this case I want to capture the bus at a specific event in my pcb, so I select the channel 1 to trigger the oscillocope on that event. Thanks for you reply. |

*&#@!!! I bought an MSO-2204EA precisely for this task! |

I have not heard back from GW Instek's technical support in the EU but I'm pretty sure they are closed for the holidays. |
