AndrĂ¡s on July 22, 2013, 09:40:27 pm ---this qestion is aimed for users who play with this scope for a relative long time and even have an agilent x2k or x3k series scope as comparison. how do you analyze spi bus with this scope? 2 channel for clock data in and data out? any quirks regarding the longevity of the scope. im seriously looking at these as the prices is damn good, even the lowest agilent model is twice the price sorry for not reading trough a 107 page topic which i wasnt interested in before --- End quote --- Good question. the SPI interface bus has 4 signal lines. At least 3 are usefull or required to monitor. I used the I2C decoder, and that has a clock and data signal so here you have no problem on a 2chan scope. I would assume you need to connect the clock and one of the data lines to see RX or TX.... Perhaps someone which has used the SPI can fill in. |

I think we have now the exact moment in which the change was made. New range is: DS2A1520xxxxx (Week 20, 2013) -> RP3300 DS2A1521xxxxx (Week 21, 2013) -> RP3300A Thanks for the info darrylp and gilbjd. --- End quote --- That was one last ditch effort to bandwidth limit the scope ;) --- End quote --- the rp3300a probes are still 300MHz, just down from the rp3300 at 350MHz. -- Darryl --- End quote --- Would it be possible to place a picture of the rp3300a probe?, I looked at the rigol site, but could not find any. |

Ok 50MHz less, no problem. The question is: Really reach the RP3300 until 350MHz? I have a P6200 probe (200MHz) and his rise time is less than the RP3300. Why? No idea! :-// Cheers! |

That looks like a nice probe, not so clumsy as the rp3300 |
