Need DDS module, 2nd round

Joerg · 2013-03-02T20:37:10+00:00

Hi Folks, Long story short, none of the DDS modules I've found so far has the ability to be sweeped or FM-modulated. This one has a signal input terminal block "SIN" but I received a response from the manufacturer that it connects to nowhere, it has no function: What I need in my case is DC-100Hz of sweep or FM bandwidth. Operating frequency under 10kHz and sweep range up to 2kHz. Of course I can whip up an analog solution but it won't be as precise and most of all not really programmable. Is there anything better? Cost is not a big issue but should be somewhat small and a display would be nice. -- Regards, Joerg

rum,

A big thing around here is a girl with a cart who makes ice cream to order, by whipping LN2 into cream stuff. I haven't had the luck to run into her, but I hear it's pretty good.

For quick chilled drinks, this seems to work

They've been using LN2 a bit much for that kind of thing:-

It makes wine-sickles pretty easily, but they're too cold to be comfortably consumed.

ice, rum,

I expect it may vary some depending on the ratios of the constituents.
