Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!

And for those having a x64 system, here are the drivers for the HDG uboot

As you see on the first page pictures, there are two power supply connectors on the board, one on each extremity.

Would it mean that Hantek run into design problems and did that as a workaround? What do you think?

when you look exactly the PSU PCB, then you will see that there are two complettly separate transformers. One seems to generate all power rails for analog part, the other (small) one for digital part and fan. So it looks like when the opto isolation option has been populated (you remember, there is currently small PCB soldered instead of opto-isolation module) the 4pin connector need to be then connected to that 4pin right conector to supply digital part of the PCB.

That makes sens. I suppose it is meant for the HDG2000C Series. Could it also be a way to have a cleaner signal on the output?

Actually, it seems to be for the 6000 series. You can see it on the Chinese site. http://www.hantek.com/ProductDetail_8_152.html In the specs tab, it notes isolation. It does come with a faster DSS chip though (500MS/s). Overclocked maybe?

AD9783 is pin-compatible 2ch 500MS/s 16bit DAC. Sure it need LVDS instead of LVCMOS interface,
but that not a big deal when using FPGA to provide the data. So to get HDG6xxx one need new DAC,
some passives, isolation PCB (what so ever they used for), OCXO and firmware dump from such AWG.
The PCB label shows HDG2000 and not HDGx000, but that might be coming from late decision etc.
So yeah, HDG6000 might really be using same PCB/PSU.
