New Rigol DS1054Z oscilloscope
pitfermi:
i have a device which has an uart interface. I am capturing the boot log using a ds1054z, i see the signal on the scope and want to decode it.
i am using roll mode, because i want to check a particular sequence of bits when reading the TX pin of the device. as soon as the bit sequence is inside the screen I press STOP button on the top. since the scope is still in roll mode, i cant enable decoding on the fly. is there a way to save the captured signal exactly as it was read and decode it later? if no, how can i decode on the fly only a particular time interval of the uart output? thanks in advance

You need to learn to use triggering.
You can trigger on specific UART characters in boot sequence..

i dont even know what the uart outputs, thats the problem. can you be more specific for this scope? or maybe a short demonstration video? sorry, i'm new to using scopes
2N3055:
Sorry but I haven't a clue what you are looking for.
All I know that you can trigger on many trigger types and you should study triggering in user manual, and then figure out which one to use for this..

Are you sure you want to do this via the Rigol at all? If you need to analyze a larger chunk of serial data, and its timing relative to other output signals is not relevant, I would strongly recommend that you read it into a PC directly (via a serial-to-USB interface and a terminal program). Much easier to search or filter the data on the PC screen.
