No, this is mosaic made from 5 images. With Canon 40D DSLR camera and Sigma 17-70mm macro lens. 


Ok, let's see what's under the hood:

Simon:
aha yes thats another way, well done, I have done that often too (make a higher res image from more than one image with pano software)

flolic:
Photography is my other hobby so making panoramic images is something I do a lot  ;)

Let's go to PSU board:


Few thoughts about temperatures, fan and fan noise. My plan was to reduce fan speed to lower noise. Before that I take some temperature measurements... I checked temperatures inside the scope with my IR thermometer. Hottest parts on the main board are definitely AD converters, followed by FPGA. They reached around 50 degrees Celsius. Other hot part is that 7905 regulator in the bottom left. But I think fan cooling is not needed for main board, those temperatures are relatively low.
On the other hand, parts of PSU get really hot. Left top (LM317) and left bottom (some diode) heatsinks are at 70C. But that diode right next to the big primary side electrolytic reached 94C!!! Room temperature was 20C.
I aborted the mission and leave fan at full speed  :(

flolic:
Rigol specifications, false advertising or...???

If you set dual channel mode and long memory, maximum sample rate falls to 250Ms/s?? Should be 500Ms/s.
Am I doing something wrong or they lie to us??
