Regular readers will know we just looked at a DIY signal generator able to generate sine, triangle and square waves. Breadboard, wires, you name it… Well, this is NOTHING like that.
If the simple DIY generator of a previous blog is not to your liking you might want to consider something like this Feeltech FY6600—50M Dual Channel Function/Arbitrary Waveform Generator supplied in this case by Banggood.
I won’t bore you with spec you can read online but the basic spec includes up to 50Mhz signal out, 14 bit precision, more stored waveforms than you can shake a stick at with the ability to store up to 50 arbitrary waveforms (hence the term Arbitrary Waveform Generator), two independent outputs, lightweight, decent display, external PC control, TTL output and a whole lot more. The video gives you a good look around this device.
I came at this expecting something rather elementary and came away suitably impressed with what the unit can do at the price. It looks well put together and everything feels responsive. It also lights up like a Christmas tree (handy at this time of year) and looks very impressive when neighbours drop by and ask it that’s a new miniature TV.
I’m going to end up using this to test everything from scopes, through RGB PWM LEDs etc. Really - lovely. I can’t immediately think of anything to complain about.
Here’s the video.
There is PC interfacing for this unit but right now I can’t find it – I’ve written to the manufacturer for more information.
Meanwhile I’ve been playing with the various options and there is indeed a DC output able to put out a steady voltage from –10v to +10v
Also noticeable is the ability to slow down to hours per cycle!!
Banggood do other instruments.
