Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!
<< < (132/134) > >>
Daruosha:
Devices with 10 MHz or 20MHz bandwidth limit are fine, I'm asking about 100MHz units.
square circuit:
I guess nobody bought the higher end versions since the hacking potential makes this AWG a great deal and it gets pretty pricey starting with the 30Mhz and up. I also wonder if the higher frequency models have any hardware differences like better op amps with better slew rate? Was this ever investigated? Hantek claims 18ns rise time for square wave on the 5Mhz and 10Mhz version and it gradually decreases with every subsequent model down to 10ns on the 100Mhz one.
Microcheap:
I'm sorry for revive this old thread but I thought here would be the best place to ask.

I got one HDG2002B and changed the BW limit, did full calibration and added the missing components to get LAN working, all went good. But, while checking the file /dso/etc/boot.sh to change the IP address and to enable telnet, I messed up with the vi commands and I think I might have inadvertently deleted some line  :palm:

Anyone would be kind and provide me a copy of this file, please?
Every thing seems to be working fine, but just for peace of mind I would like to check. Yes, I did make a backup of everything else before start changing things but forgot this one  |O

If still there anyone interested in this function generator I can post my nanddump and firmware copy here.

PCB 1006

@Microcheap: It would be very nice if you could post your firmware (Software: 1.00.3.03.11 (171116.0) ) here...

Do you know if it is the lastet one?

Did you encounter any problems?

Thank you very much.
Microcheap:
Sure, Do you want the flash dump or just the update file with the lastest firmware?

My function generator has being working without a problem. I don't use it very frequently, but apparently the main bugs reported in this thread are sorted and it is stable, I've never had problems with it hanging or rebooting.
