KKmoon 60MHz Signal Generator, 2.4 inch TFT LCD Digital DDS Dual-Channel Function Arbitrary Waveform/Pulse Generator,250MSa/s 8192X14bits Frequency Meter,VCO Burst AM/PM/FM/Ask/FSK/PSK Modulation

A tremendously capable piece of equipment at a very good price.Haven't hooked it up to a scope to check outputs, but it works well for what I bought it for.When I started working with electronics 40 years ago something with half of this capability would have cost 10 times this in 1980's money.Only downside is that it comes with no doumentation.In the original version of this review I posted a link to the manual and control software:This was disallowed, but google "feeltech fy6800 manual" and you should find it OK

This KKMoon Signal Generator/Counter is a re-branded FeelTech FY6800 unit. It's incredible value for money. I paid £66.49 and it's worth every penny especially as the main processing is done by an Altera Cyclone 4 FPGA. There are too many features to list so it's best to search YouTube - there are some well made reviews there. I tested the maximum output of 60Mhz at 5Vpp - my DSO measured it at 60.0006MHz - I've a feeling that the FY6800 might be more accurate than the DSO. The only downside is that it's very lightweight, just 620g, so you need to use both hands when pressing the buttons.The manual and software can be downloaded from the Feeltech website.There's a newer version, FY6900 but this is really just a FY6800 with an updated case/stand and is currently more than £100 from China.As a hobby signal generator/counter this is well worth buying - recommended.

This generator is so functional and feature rich that it scores 5 stars as a bench signal generator on value for money. It has unprecedented signal frequency accuracy, and resolution, which makes it valuable as a reference oscillator for checking other equipment.It does not come with a manual or indeed any documentation, but the web site to get the manual and drivers is listed on its screen. The manual is useful, but the signal generator is easy enough to use as a standalone generator after a few minutes play.Watch out for the external frequency counter protection. The manual says 20V ptp whereas the generator itself says 5V max. This is because of the 100 ohm input impedance. 20V into 100 ohms is 4 watts, and would fry the input resistor.I consider the drivers and software as extras, and so their weakness does not reduce the star rating. The USB driver is in rar format, which is a pain to then decode down to zip format. The pc software has no help file or manual, which is a pity. Some parts are self evident. The text doesn’t fit properly in the text boxes due to incorrect scaling in the software, which makes it look a bit cheap and badly written.You obviously need the software to upload arbitrary waveforms. It is difficult to draw a waveform nicely with a mouse, and saving the waveform to the computer, cleaning it up in excel, and re-importing it doesn’t work cleanly. I eventually got it to work after some fiddling around. It is a bit of a pain, but gives an excellent result.It is hard to imagine that this generator is robust enough for normal lab use, but for a hobbyist it is absolutely fantastic.

This is super good value for the money! It's unbelievable what this thing does compared to my old function generator. My old one is 6 MHz and now I got 60 MHz for a fraction of what I paid for the old one. And this one has so many features, and two channels compared to one. The only thing that worried me before I bought it was some people saying that the BNC connectors were floating instead of grounded, but that was not the case. They *are* grounded, I measured it with a multimeter. What more can I say? I've already triggered its burst function from another generator and that worked perfectly too. The display looks good, the whole device is very light and easy to move around. It's super good value for the money!

This is a great value device. Software and manuals are available, but no longer from the original provider, links are supplied in the Q&A section. Does what it says, seems to struggle to provide a stable, low frequency wave form (e.g. 1Hz), but no complaints about accuracy or stability at more normal frequencies! Good value, comes with all the leads you'll need and pretty intuitive to use, even without the manual to hand. Great selection of built-in wave forms. I've not tried the PC software yet, but that promises to provide the ability to create completely arbitrary wave forms for specialist applications.

Very light build and buttons can make operating this unit a bit fiddly, but my goodness the facilities this unit offers is quite remarkable and go way beyond the capability of traditional signal generators of my uni/lab days. Exceeded my expectations. I shall see how this unit holds up over time but hopefully with the light use it will get in my 'workshop' it will be fine. Amazing valve at this price.

I wanted this as an RF and AF signal generator for the alignment of old radios among other things. It is ideal for this purpose but also for many others too. It has two channels and one can be used to generate the carrier and the second can generate the modulation frequency, which can be AM or FM plus other types of modulation. Each channel can also generate sweep frequencies. It is quite intuitive to use, I was using it easily before downloading the manual! You can also download PC software from which you can easily control the generator's many functions. As well as having a two channel signal generator, it has a frequency counter built in. An impressive bit of kit for the money.

Manual has to be downloaded from the internet and is not easy to find the correct one. The manual is obviously a translation and not easy to understand. The actual signal generator is good with many waveforms available and displays the actual signal which is very useful. It also helps to read some of the Amazon previous reviews to understand some of the facilities.
