Review: Hantek DDS 3X25. Anyone own one?

Hi all,

It seems I have some progress since my last post and now I have a lock in amplifier working by using the Hantek function generator. However, when I scan frequency the lowest frequency step I can reach with Hantek is 125 Hz. Is this a characteristic of this module or am I doing somewhere a mistake?

Hi,
I wrote a Python library to access Hantek DDS 3X25. It was inspired by tymm. It works in Linux (tested in Debian) and should work in Windows.

What works:

* (unreliable) waveform sending
* clock divider setting
* digital IO pins
* frequency and pulse counter
Library: https://bitbucket.org/kuzavas/dds3x25/src
Information on the hardware and protocol: http://sigrok.org/wiki/Hantek_DDS-3X25

Would this work on a raspberry pi? :)
domasj:
It should work on Raspberry Pi.

I'm thinking if I could make a standalone unit with a raspberry pi and a LCD. Need to finish my current projects and I might see if it's worth a shot.
