Function generators are useful in a ton of applications from RF to embedded logic. They’re not usually super cheap though. Good news: we found a kit. The FG085 MiniDDS Function Generator is a ‘some assembly required’ kit that becomes a flexible, functional and easy to use frequency generator. Just solder the through-hole parts in place, attach the face/base plates and before you know it you’ll be generating sinewaves at frequencies up to 200KHz! But that’s only one of the tricks this thing can do. Three different operating modes allow the FG085 to generate 7 different types of continuous waveform as well as servo test and control signals in micro-second resolution.

The LCD screen and menu system make this an easy instrument to operate. Frequency, amplitude and offsets can all be set with the number pad and incrementally adjusted with the rotary encoder. The incremental step size can even be adjusted to make sweeps over a wide range easier to handle. The FG805 can generate a peak to peak amplitude up to 10V with an offset range from -5 to +5VDC. It can even be used as an adjustable DC voltage source by setting the amplitude to 0.

Includes:

  • FG085 miniDDS Function Generator PCB with SMT parts installed
  • Acrylic Faceplate and Baseplate
  • Alphanumeric LCD and Headers
  • Through-hole Parts Bag
  • 15VDC 1A Wall-wart Power Adapter
  • Quickstart Assembly Guide
  • Output cable (BNC + clips)

Features:

  • Generates continuous waveforms of Sine, Square, Triangle, Ramp (up and down), and Staircase (up and down)
  • Generates servo test/control signals in micro-second resolution with user programmable pulse width, amplitude, and cycle
  • Set the frequency (or period), amplitude, and offset with number pad - quick and straight-forward
  • Frequency (period), amplitude, and offset can be incrementally adjusted with rotary encoder
  • Settings are memorized after power down
  • Can be used as an adjustable DC voltage source by setting amplitude to 0
  • Frequency range: 0 - 200KHz (Sine)
  • Frequency resolution: 1Hz
  • Period resolution: 1ms
  • Amplitude range: 0 - 10V peak-to-peak
  • Offset range: -5V - +5V
  • Memory depth: 256 bytes
  • Sample rate: 2.5Msps
  • Output impedance: 50 ohm
  • Power supply voltage: DC 15V
  • Current consumption: < 150mA (without loading)
  • Dimension: 155 X 55 X 30 mm
  • Net weight: 100 gram

    I could not get this to work at all. I followed the manufacturers instructions to the letter and plugged it in, and... nothing! No power, no LCD. I hooked up a multimeter - none of the components were reading a charge. I used an oscilloscope & still got nothing. I don't know if I got a faulty unit, but I did check the components before soldering & they were fine. I don't know what I did wrong or if it is a problem with the PCB (NB: some of the components come presoldered to the PCB). It seems like a fool-proof project, but I guess not. Very disappointed with this project; first one I have ever done that could not be salvaged at all. (Posted on 27/04/2017)

    This is a pretty good bit of gear, and seems to be good value for money with a good range of functions at a fairly low price.

    Anyone taking this on would need to be confident of doing the (through hole) soldering that is required. All the SMD soldering is done, but the soldering required is not trivial. A fair amount of experience assembling PCBs would be good background. There is quite a bit of soldering to be done (e.g. includes 20 switches with 6 contacts each).

    It is important to get all the switches nice and flat down, otherwise fitting the push buttons can be difficult.

    A slightly larger (perhaps 2 A4 pages instead of 1) of assembly instructions would be helpful too! (Posted on 15/02/2017)

    Comes with an easy to follow step by step instructions to assemble together. Very easy to solder. Very easy to use.

    Only 2 issues so far. The 1st issue is just a minor issue. The LCD display is directly soldered rather than using some sort of connector. I have mistakenly forgotten to solder a capacitor that goes right on the other side of the LCD. As I have already soldered the LCD display, I could not easily put the missing capacitor.

    Second issue. I don't know if this is an issue at all. Or may that's the way it is and it is an issue at all. I don't know but frequency is not 100% stable. I set it at 100 Hz but it goes down to 99.6 Hz or something. Not sure if this is normal but the output waveform flickers just a little bit on the oscilloscope.

    When assembling don't forget to bend the BNC washer and use a bit of trimmed off component end to extend it because the washer tail is not long enough to reach the PCB.

    The multi turn potentiometre is clickable as well but I am not sure what it does.

    Nonetheless it is very easy to use and a great value for money. (Posted on 17/08/2016)
