FY6900-60M 2-CH DDS Arbitrary Waveform Pulse Signal Generator/Frequency 60MHz DDS Signal Generator

The Feelelec FY6900 Dual Channel Function/Arbitrary Waveform Generator is a versatile and affordable tool for hobbyists, engineers, and educators. It offers a wide range of waveforms, including sine, square, triangle, and arbitrary signals, with a frequency range of up to 60 MHz. The dual-channel output allows for simultaneous signal generation, making it ideal for complex testing and experimentation.The device features a clear LCD display and an intuitive interface, though the menu navigation can feel a bit clunky at times. Build quality is decent for the price, though it may not withstand heavy industrial use. The inclusion of USB connectivity and PC software adds flexibility for remote control and waveform editing.While it lacks some advanced features found in higher-end models, the FY6900 delivers excellent value for its price, making it a solid choice for those needing a reliable and functional signal generator on a budget.

I bought this at the last minute for a specific application. I needed a signal generator capable of generating a sine wave with a 10 volt offset, and this gadget did the job perfectly. It seems to have an identity crisis - the Amazon description says Bulipu, the website says Feeltech and the front panel says FeelElec - but whatever its name is, it's well designed, easy to use, and even fun to play with. I managed to find all the functions I needed without instructions, although a manual is available on the web.For such a cheap device the capabilities are impressive. Two independent AWGs, with the ability to modulate one with the other (AM, FM, PM etc.) or to adjust them in tandem with tracked frequency or amplitude. Phase difference between them is adjustable. Output range up to +/-20 V depending on frequency. Sweep of various parameters. Frequency resolution down to the microhertz. A good selection of standard waveforms plus space for about 60 arbitrary ones - you need to use the Windows app to define them. The UI is basic but efficient.The only thing I don't like is the adjustment wheel. It's very small and has quite heavy friction, so it's not easy to spin. You have to get used to it though as it's the only way of manually entering values (the alternative is to run the Windows app and control it over USB).For the price, I'm very happy with it.

For the price you get a lot of capability. I've checked the outputs from this generator and it is accurate so I can rely on it to give me accurate inputs to the system under test on my bench.It's a slight shame that it does not store your last settings between power offs, so if you are working on a project and need to have an overnight break, you either have to power off and then re-setup on next switch on or leave it powered through the night. Given the accuracy and capabilities for the price this does not detract from my 5 star rating.

Good value unit.

Quality good.Purchased similar before and always had instructions.This does not have any. So how I program the settings is anyone’s guess.Tried to contact manufacturers but no response.Ver disappointed.

lots of features, takes a bit of working out, no manual in the box, so downloaded from the net.leads ok, but does what it says on the tinfor the price it's a great product

UPDATE - THIS IS A WARNING - after successfully using this on a few occasions it has STOPPED working.I cannot contact anyone, it is frustrating.Once out the Amazon returns time period you have no rights.It is worse than buying at a car boot sale.The good points are the high voltage output. The good signal quality, and the accuracy of the read out.The minor bad points are the fiddle set up and small display.In my view an excellent purchase.

This is a toy and doesn't perform as specified. The level of the sine wave starts dropping at about 7Khz. By 1Mhz the level is about 10mV. The rise and fall times of the square wave are shocking and the triangle wave looks like a sinewave. The only thing that is correct is the frequency. It abviously uses one of the cheap AD9833 modules or similar and has a dreadful frequency response on the output. Don't waste your money on this. Mine is now in the bin.
