Find it amazing that Siglent can offer at this price point, same for low end Rigol HD, altho the Rigol hardware seems good but firmware is lacking.
Sure Siglent's leveraged off the enormous DSO IP investment over the years which kept the direct hardware and firmware original development costs very low, but the recurring BOM component, assembly, and test costs must also be kept very low.
Suspect that Siglent is getting a fallout version of the core 12 bit ADC (lower chip cost), and looks like they've simplified the PCB and Power Supply circuitry. Likely a lower end slower FPGA also, but seems to be using same quality touch screen.
Anyway, hopefully the intro firmware will be more polished than the Rigol, and frequent updates, maybe as good as the SDS2000X+ which we've all been impressed with!!
So hats off for offering such an interesting version of the higher end HD model at this price point
Best,
