Arbitrary waveform DDS signal generator from MHS-5200A series 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.
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 500s) 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.

Questions & Answers

  • Q Hello, Can the two outputs be controlled independently? I mean for example 500 Hz at output 1 and 700 Hz at output 2 AT THE SAME TIME? Thanks

    By Edmond Petitjean November 5, 2018

    A Yes,you can. Frequency Range can be rated,thanks.

    All I've done is try out the built-in capabilities, just to be sure it wasn't DOA, and was a version with the advertised features. Everything works as expected. Any shortcomings in signal quality are minor and expected given the price point. I connected it to the Siglent SDS1102CML digital scope for these tests, and was reminded how easy that oscilloscope is to use as well. First, anyone interested in learning about this signal generator will find a lot more online about the model MHS-5200A, which appears to be the exact same unit, under a different name. There are reviews and upgrades, including fixing the over-bright display (a minor issue) and correcting some of the distortion in the sine wave output (how important this is depends on how spectrally pure an output you need). There is also some aftermarket software hobbyists have developed for uploading arbitrary waveforms, if the supplied software doesn't meet your needs. Some people have even managed to "close the loop" and download waveforms captured on their digital storage scopes (like the one I use) into their computer, edit them, and then upload them into the signal generator. This is way more than I need - I'll likely never attach it to a computer - but some users of this device will doubtless want to follow these brave hardware hackers' lead. A nice English manual is available from one of the serious hobbyist sites, and maybe other places too. It was written by an English-speaking hobbyist based on the Chinese manual and online sources - it covers all the basic internal functions with clarity. I don't like posting links, so just Google it yourself. Search for MHS5200.pdf. Follow a result on about reverse engineering the serial protocol, look at post number 18 and you'll see a link to the pdf file on github. It scans clean of malware and is very clearly written. However you find it, it will be useful. While I didn't have my scope analyze for spectral purity (see MHS-5200A YouTube videos for that), I did run the generator through its built in paces. As others have noted, the square wave begins losing its crispness much above 1 MHz, and is pretty "round" by the advertised 6 MHz. Sine waves look pretty good all the way to 25 MHz. Locking the two channels works, all the wave shapes work. Adjusting the duty factor of square waves works. Adjusting the relative phases of the two channels works. Sweeping the frequency works as advertised. The input frequency counter works in its various frequency, period, duty factor, etc., modes, including when feeding back one of the output channels into it, set up prior to moving to the signal input part of the menu. (Not that anyone with a modern digital oscilloscope needs this feature.) I didn't test the rear panel TTL inputs or outputs. I also didn't try saving a setup of the controls into one of the internal memories (probably works). Adjusting the amplitude works, but I forgot to try the offset - I'm sure it works too. I noticed that the square wave has a small "back porch" (slight drop in level near the trailing edge), even at low frequencies, but is within the range of expected signal impurities and would just about never be an issue. Amplitudes and frequencies agreed extremely well between the signal generator and my digital scope. Conclusion; This seems to be the exact same device as the more commonly discussed MHS-5200A, and all the features and functions that I tested work as expected (none involving a computer were tried). It is a great value for what it can do and has even more potential when interfaced to a computer, or if modified for greater spectral purity. Amazon seems to be selling, in the KKmoon, an MHS-5200A under a different name, for a very good price. I saw no issues with the build quality or construction of my unit. Finally, I didn't find the controls as hard to fathom as I expected. They can be a little slow to navigate, but with a few minutes use they seemed fairly natural and required no reference to the manual. The English manual did come in handy preventing a lot of guessing at a few points, so I do recommend it highly.

    What an amazing use of micro-controllers for direct signal generation. A bit cheesy use of just 6 click buttons, but a real nice encoder knob for the many adjustable parameters and features up the wahzoo.. Locating the (large) knob at the far right is the best ergonomic location if you ask me. I've been working in electronics since age 13, that's lots of years ago and I know great engineering when I see it.

    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.
