Hi All! I'm newbie in this forum, this is my first post, and first of all, i would like say: It's great!!
As paul_ius I'm looking for the same, my first own oscilloscope "multipurpose". I worked in the past with some Tek and R&S. At that time I only needed one single channel, but now I'm developing microcontrolled based systems, Arduino and PIC for now.
I'm developing a system with 4 rfid SPI readers, it could be interesting to see MISO, MOSI, SCK and SS signal together but as I haven't my oscilloscope yet, I'm not sure if could be a need or only a extra. Siglent sds1202x-e can decode SPI, I2c, CAN and other serial protocol wich I don't remember now. I think the most important problems with SPI could be propagation times and interferences, to do this you only need two channels if I'm not wrong, as many other things, you could use multiple channels todo some more confortable but many times isn't a must.
I'ts clear that Siglent scope is newer and as I saw in reviews (youtube) looks more precise than Rigol, faster and better FFT, better trigger in Siglent and a few things where Siglent is a bit better than Rigol DS1054Z, so my concern is about if I'm looking for troubles with timings and interferences, if I can't see it fine with Rigol ¿why 4 channels or 20?. I need see what is happening in my circuits, but really I don't know if there is such difference or Rigol is more than sufficient to do my work. I think these are excellent value oscilloscopes but for now I haven't clear wich is best for me.
Thank you to everyone here, it's very interesting to read all the opinions and thanks to it I'm sure I'll choose the right for me!
P.S.: I'm sorry if my English is not the best in the world, but I hope you can understand me fine!.
