I'm considering the purchase of a Rigol 1054z. I've watched the EEVBLOG videos and searched around the forums a bit and, for the most part, can't find that much negative feedback other than just some things one has to get used to with a new scope. My use will be fairly general, I'm an EE and do quite a bit with microcontrollers and debugging of serial interconnects (i.e. UART, I2C, SPI), I also dabble in Rc for a hobby. I think the scope will fit my needs really well (and of course money is tight). Does anyone have any negative issues that affect the performance of the scope?
Do the various 100mhz upgrade and feature unlock approaches still work for these scopes? Are there any issues with doing this and is everything reversible if necessary (i.e. warrenty claims). If anyone has any specifics regarding any of this please share.
I don't think I'm fully understanding the recording capabilities of the scope. I know it has both the ability to record/playback (via software upgrade) and the general ability to save data to a USB drive. Can all data be saved to a USB drive? Are there any software options for playing back and analyzing the stored data off the scope? Is it possible to playback the data through the scope? I know the answer to this depends on many factors but assuming 2 channel usage about how much time can be captured using the record/playback option?
Really appreciate any help.
