Review: Hantek DDS 3X25. Anyone own one?

This is good to know, and thanks.  I've not had any problems running 32 bit drivers in Vista 64, and worse case I've done it in compatibility mode.  But its best to get confirmation that the Hantek drivers to indeed work.

Due to a hard-drive crash, I'm now running it on 64-bit Win 7. The drivers are available on the Hantek website. I installed Goltek, plugged in the 3x25, and installed the drivers via Device Manager. No problems found to date.

hi
i just read part of this long threat and it seems you did a really good job fixing few bugs :)

@Mechatrommer
i'm wondering if your source code are available, can i dowload it somewhere ?

part of what i might find interesting about this  fcts gen its his sdk i might need to take a look in it :)

 :D

Mechatrommer:
download the device manual and sdk its all there with program example. i dont think you'll be interesting at my codes.

Ok, this is strange. I can no longer save a waveform to be displayed on power-up. I installed Goltek, then extracted the 1.04a files over the originals. I can save the waveform with the Hantek software.

When I select "Save Wave on Device Startup" the little red indicator "light" near the USB indicator flashes, indicating it has sent something to the Hantek.

I CAN save a waveform using the Hantek software. If I later try to save a different waveform using Goltek, it erases the stored waveform. To ensure it is not related to the increased bandwidth, I switched to 2kHz frequencies for testing.

If I shut down Goltek (or click the USB symbol) the indicator flashes and the waveform disappears from the scope. If I simply unplug the USB cable, the waveform continues as long as the Hantek is independently powered, but does not reappear when the device is cycled even though I tried to save it. (note: it does reapear if saved with the Hantek software, but not overwritten by Goltek).

I installed the 32 bit drivers from the same downloaded package on an old laptop running XP (32 bit Pro, upgraded to SP3), and have the exact same results, so it's not a 32 bit vs 64 bit or a Win7 issue, as far as I can tell. I'm sure that Mechatrommer had this working. I wonder if there could be some slight change in the drivers -- my original CD is damaged, so I'm using the drivers downloaded from the Hantek website. The 32 bit driver file is dated 06/11/2009 and the 64 bit driver file is dated 08/06/2010 in the downloaded package.

Is anyone else having this problem?

torch:
Don't put that one on the website!!!

It won't start. Running the program produces the error message "Goltek Controller has encountered a problem and needs to close. We are sorry for the inconvenience." and the typical request to tell Microsoft about the problem (as if they would ever do anything about it anyway!)

I copied just the goltek.exe file and encountered the problem. Then I copied the intmath.dll file and tried again -- no joy. (this was on the Win7 64 bit machine)

So I tried copying goltek.exe alone on the 32-bit XP machine -- same problem. Just to be thorough, I tried copying the intmath.dll too, but again, it just crashes.

I reverted to the 1.04a version of goltek.exe but left the intmath.dll as the newer, larger version on both machines. Goltek starts fine that way. (but of course, will not save the power-on waveform to the Hantek)

EDIT: I forgot to mention that I installed the XP trial from a separate download, just in case the original was corrupted in the download process.
