content: So im able to buy either a used RTC1002 (couple hours) or a new SDS1202, which should i buy? (Both the Same price) Ofc my Heart sreams "Take the RTC!!" But i dont know If there any bugs with the RTC, since its a lower end from R&S?Im doing Basic stuff in the Audio section with my scope so far, so either is fine for me, but a rtc1002 for the half price? Sounds attractive.

content: Looks like the RTC also has optional logic channels (there's a connector on the front panel for it). The 1202X-E doesn't. I'd imagine the logic probe kit for the RTC is rather pricey, though. No idea if there's been any effort to build one up like there has been for the SDS2000X+ series.My inclination would be to go for the RTC unless the capabilities it comes with are insufficient for your needs and can be met by the 1202X-E. If you have time, you should review what videos there are of the RTC and of the 1202X-E, to get a sense for which one might appeal to you more.Dave Jones seemed to like the HMO1202, which looks very similar, rather a lot:However, since the RTC is used, you should certainly make sure it functions properly. Run the self-cal, hook probes up to the compensation ports, etc. If the basics like that work, then it's almost certain that everything works.

content: If you don't mind, I'll throw in a variation of the RTC - check out the Hameg / Rohde & Schwartz HMO1202 Dave reviewed. It's the predecessor of the RTC and mostly identical, but it has 50 Ohm termination - a feature that was stripped from the RTC and also the RTB. My guess is they want to market it as a "premium" feature only available in the RTM3000 and up...Anyway, I had it for a few years with full options and it is a pleasure. Up to 300MHz, up to 16bit ERES, optional 8ch logic analyzer, component tester (!) - where do you still get that in a scope?, boots in 10 sec, 4-bit pattern generator....Real talk: The FG tops out at 50kHz (not a typo) and is a toy. Also, the short memory limits the sample rate at extreme time bases. The Trigger LED is annoyingly bright. Otherwise, it's a damn fine scope.Is it expensive for an entry level scope? Yes. But oh so worth it. I was really sad to let it go and I miss it, but I could not justify keeping multiple bench scopes just because I like them.EDIT: If you want more info, let me know.EDIT2: The RTC goes to 300MHz (vs 200MHz max for the Siglent). RTC1002 is the name of the base model, which is then upgraded with options and e.g. the 300MHz version is called "RTC1002 with option -B223" or just "RTC1K-302" depending on the vendor. Which one are you looking at?
