Arbitrary waveform DDS signal generator is a multi-functional signal generator with high precision and high performance. It adopts large scale of FPGA integrated circuits, high-speed MCU microprocessor and SMT in the inner circuit, which can greatly improve the anti-interference and lifetime of the instrument. The LCD display is divided into two lines: the top line shows the current frequency and the following line displays additional parameters or functions. This instrument is of great advantage in generating signal, scanning waveform, measuring parameters, etc. It's an ideal testing or measuring instrument for electronics engineer, electronic laboratory, teaching and researching.
  
Features:
Can output arbitrary waveforms and conventional function waveforms(sine/triangle/square/sawtooth wave and TTL signal).
All functions are digitally controlled, precise and stable.
Dual-channel output, can work in sync, phase difference is adjustable.
With linear sweep(Max. up to 999s) and logarithmic frequency sweep functions.
Signal of both channels has built-in sophisticated -20dB attenuator in order to reach the minimum amplitude resolution 1mV.
With 120% ~ + 120% DC bias function.
4 TTL output(phase difference is adjustable).
Has a frequency measurement, period measurement, positive and negative pulse width measurement, duty cycle measurements and counting function.
With USB interface, after the connection with PC, the PC can be used to control the instrument.

    First thing I noticed It was easy to set, Its the easiest to set of My other frequency generators but that Is once You know how to set It, there was some things right out of the box but there were some things I would have Not been able to figure out, I had to go watch some videos to figure It out. To adjust the level at the top of the screen click the bottom left button then push the top right button and do It again to go to the bottom of the screen. To switch channels click the bottom left button then the top left button, To start click the bottom left button then the bottom right button, You must ad just the settings as the frequency before It will start, I thought I got a defective one because I did Not know that. The amplitude power output will Not go to zero volts It goes to from 00.20 volts to 13 volts but It will read 20 volts. Also for the program to work You must have a newer Microsoft Operating System It would Not work with My old Windows XP A quick history about Doctor: Rife cured 16 out of 16 People of cancer In 1934 using am radio frequencies waves through a plasma bulb, but a business partner tampered with the frequencies and They were selling machines that did Not work which gave big drug companies a chance to put Them out of business and In the 1950's Doctor: Crane wanted to reinvent the Rife machine but using Audio frequencies and Tens pads which did Not work as well as the original Rife machine. I bought this because I wanted a 3.3 MHz carrier wave for a Rife machine but I did Not know how easy It Is to adjust. This will work as a Doctor: Clark zapper or Croft zapper It has adjustable voltage up to 13 volts output though It will read 20 volts output the screen shows AMPL short for amplitude voltage that Is the voltage output adjustment. I do Not think It has enough voltage output for Tens pads or any Non metal connection, but It has enough voltage out put If used with metal as Copper or Stainless Steel, Using Copper handles I could feel the voltage at 6 volts and 12 volts I was getting a good zapping and what I always say If You can Not feel It shocking You the Its probably Not doing anything to the pathogens. Also Doctor: Clark said to use a positive offset, on screen says OFFS This can also be used as the frequency generator In the Rife/Doug coil machine, A Technician In a video said this has a ring In the Square wave and put In better parts but I do Not know how much that will effect It. The Spooky2 software program will Not work with this Generator, It did Not detect It, but years a go We were able to out smart that Internet virus company (You know that big company that puts their big genitals where It does Not belong and freezes up Your account for No understandable reason) and I bought a Spook2 generator but became frustrated trying to adjust the settings I tapped the screen with My finger It and broke the LCD screen but the Spooky2 program still recognised It and asked to look for more generators but I have Not tried It yet. Also the Spooky2 booster does Not fit this Generator but all It does Is link the 2 channels together and has a 103 resistor for making Colloidal Silver. It will Not work as a Doctor: Beck, Blood Electrification unit or a Tens machine, both Tens machines and the Blood Electrification unit Is around 50 volts AC output but the Blood Electrification unit Is set around 4 Hz and Is higher amperage than Tens machines, that Is why Tens machines are everywhere at low prices because they do Not have enough amperage to do anything a Tens machine will shock You but does Not even have enough amperage to light a LED bulb...........

    Seems to be quite accurate, checked with my Digital Oscope. It comes with a piece of software for Windows. With the software, connected through USB to a Windows computer, it is a lot easier to set parameters. On the other hand, the computer has to be running for the software to be used, duh. Of course! There is however a flaw / bug in the device firmware during power on. At times when powered on, the display is corrupted and so are the control functions. Power off and on again has fixed it in the past. Otherwise, at the price to performance ratio, it is quite usable for some bench projects. I don't know why it sometimes doesn't initializes at first power on. From my own experience in programming micro controller, I guess there isn't enough delay to initialize the micro.

    Hardware Great for the Price, but need to have better software sent with the Unit on the small disc. Missing main program and you have to read through all the reviews on this sight to get to the point you can program the unit via the USB cable. A bit shy on documentation but again reading through these reviews and you will be able to get by. It may not directly answer all your questions, but you will come away with enough to be able to use most all of its features. Again it is a very good unit for the price. So because of the poor / missing files I deducted 20% and could only offer 4 stars.

    Great signal generator for the money, tons of functions and abilities. My only complaint is that at low voltages (>500mv) the signal is pretty noisy on the scope. Otherwise, performs very well.

    The UI is rather clumsy, but it generates all signals I needs for a pretty good price.

    It works nicely and a am glad the signal is variable.

    It has a few minor issues with signal quality at very low frequencies or very high duty cycles, but nothing terrible. You probably aren't going to find a better dual channel DDS signal generator for this price.

    Well worth the money. I was considering building a signal generator until I came across this. Rock-solid waveforms right up to 25MHz. UPDATE: Frequency adjustment stopped working today, one week after the return cutoff date. No way to contact seller. UPDATE 2: Several attempts at disconnecting power and rebooting failed to solve the problem. However, after spending a day on the shelf I decided to attempt some troubleshooting. When I powered it up, it was working to specs again.
