FeelTech FY6600 Waveform Generator

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.

Read on…

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.

  1. I was impressed by the size of the unit compared to my SDG1025. Couple of things though. A menu for the waveform select and use the dial would be easier than having to press your way through the list.
    An ON and OFF button for each channel would have been ideal for when setting up the output. Easier than unplugging the cable each time.
    Does it have a DC option? One of the nice features of the unit I have is you can set a DC output voltage that can go negative to positive or purely positive from zero and then use the dial to increase and decrease this up and down by as small as 1mV per step. Handy for testing an ADC input. I also have a small circuit that converts 0-5V to a 4-20mA current loop and using the generator to drive the input.
    Overall that unit does look pretty good and the price is excellent for the features and the likes of the white noise is good for testing op-amp inputs to an ADC etc.

    1. Right, I've tested the DC output - it goes from -10v to +10v. I've also had a play with the unit at it's slowest - well not anywhere NEAR it's slowest.. but putting the Owon scope onto IT's slowest, I recorded 2 cycles over several hours !!!! And the Feeltech can go CONSIDERABLY slower than that!

  2. Pete, That's an interesting AWG so I had a poke around the web and found this on the EV blog
    "My FY6600 BNC-ground to Earth-ground Voltage is 94 Volt.
    Zing zing zing, not happy about it.
    Will have a look for a cheap 30VA isolation transformer."
    posted in August this year, it seems there are concerns about the internal PSU. Have you had any indication of undue AC voltage on the BNC connectors ?

    1. I will check right now...

      Ok, well the AC voltage between my BNC connectors and ground is precisely Zero.

      Still - worth checking.

      The amount of kit that Dave at EV blog has hooked up - it could be anything...


      1. Hi Peter, Great News that you had no issues with AC to ground, it was a hell of a long thread on that particular topic. A guy from Feeltech was on it at one point so its possible the issue was rectified on the latest versions like yours. It wasn't Dave himself who made the comments rather it was forum members.

        1. Thankfully things do change in time.... I'm busy putting a 3D printer together that videos on the web said needed a 3d printed bracket to make sturdy. By the time I got mine and extra metal bracket was supplied. Sadly they forgot the bolts to go with it!

  3. I have a FY6600-M60. Works so far. I have problems with the supplied USB driver and the program drivers.
    The FY6600 PC Software when run shows this error:

    Component ‘richtx32.ocx ‘ or one of its dependencies not correctly registered or a file is missing or invalid.

    Run on windows XP and 7. Same problem.
    Any help is much appreciated.
    Tried feeltech web page D.L.s still no Good.

    1. Hi William,

      NATools programs use Visual Basic. Until recently, Microsoft automatically installed the VB runtime library when Windows was installed. With recent versions of Windows, that no longer happens, and you need to get the missing library, or at least the RICHTX32.OCX file. Search for it online - it's easy to find. Here's how to install it:

      For 32-bit Windows:

      Copy it to c:/windows/system32
      Click Windows Start icon at bottom left
      Select All Programs, then Accessories
      Right-click Command Prompt, then select "Run as administrator"
      In the command prompt, type: "regsvr32 c:/windows/system32/RICHTX32.OCX" (without the quotation marks).

      For 64-bit Windows 7 or later:

      Copy it to c:/windows/syswow64
      Click Windows Start icon at bottom left
      Select All Programs, then Accessories
      Right-click Command Prompt, then select "Run as administrator"
      In the command prompt, type: "regsvr32 c:/windows/syswow64/RICHTX32.OCX" (ditto)

      This will sort out the problem.
