You think the same team which designs the high end R&S RF gear is working on low end oscilloscopes? I'm 100% sure they are not. If the HMO1202 was build to the R&S high end specs it would have a full aluminium inner chassis, the board mounted firmly onto that chassis and the input BNCs bolted to the chassis as well. But it is not... It is a Hameg (which never was high-end; more like Europe's Rigol) with an R&S sticker on it.
Yes, i knew it already, it's a revised Hameg DSO, IMHO in its past story Hameg had pretty decent equipments on its catalog, many schools used them for young students with proved reliability.
I already said that i share your doubts about the front BNC connector mounting method, i placed the question to Dave, let's wait for AU daytime to see what he has to say about it.
About Rigol i will dare to say that among all known chinese TE producers they currently have the best building quality, take a look to tear down videos for DS2000, DS1054Z, DSA815TG, DSG815 to say some, and look to pcb layout, soldering quality, psu component topology, case and shielding mechanical precision/robustness, electrical harness care and so on.
We are talking about a brand that actually design in house what it sells, i have an old DS1022CD that still works on my table, at the time of the purchase all the rest of chinese products in that price segment was pure cr@p or bad Rigol copy.
So saying that Hameg was like the "Europe's Rigol" it's like to make a compliment.
Sadly i cannot say the same thing for Siglent, at least for what concern metal chassis, soldering quality and care of overall details.
I mean, all those soldering oops & balls, hammered tincan chassis, PSU transformer ferrite core loose clip and so on spotted on SDS1202X tear down, a unit (i think) supposed to be under Dave's magnifying glass till it's departing from china, well not a smart move.
It's a pity, because this model has an interesting performance / price ratio, if the FW is up to HW potential.
