    Good news: The unit is working. Controls is rather friendly and intuitive clear. FW ver.4.1. On the whole it conforms to the description. Bad news: - Bad packing, inappropriate for post delivery. The unit box looks as if elephants have danced on it. - Mains cable is with crappy chinese plug, not European standard. No adaptor even included. - Switching power supply is a total crap. You have to replace it with a classic linear one. - Dangerous high voltage leakage from PS. The voltage between generator’s ground parts of all BNC and mains earth (or other laboratory equipment ) is 100VAC. You may easy get an electric shock and fry delicate equipment and microchips. - Sin wave has glitches at the zero crossing point and half way long - At 20VAC output waveforms are intact below 5MHz, at higher frequencies waveforms are significantly corrupted - At 24MHz the amplitude significantly decreases - You can get usable waveforms only below 5Mhz and below 10VAC of output Conclusion: A good generator for testing audio and some TV equipment, not suitable for ham radio.

    I bought this unit to replace an earlier model. This model has remote facilities which I wanted to use for automatic testing. These are the problems: 1) The upper frequency limit is 24MHz but you cannot set the frequency directly to more than 9.999999 using the <> buttons and the dial. You have to go to the units MHZ position and just keep turning and you will go over 10MHz. When you do this the 0.01KHz position disappears too. - see photos 2) Related to 1) the display software has a bug in it. If you program 10MHz the last digit (0.01KHz) disappears. You can still set the lowest digit but it does not show. Sometimes you also get the display 999.9999kHzz - clearly a problem. The good news is the actual output seems to be ok. 3) The included disk includes the Host Communication Protocol V1.2 document. Either this is an earlier document or it is incomplete. as: a) There is no command to set the frequency above 9.99999999. The command size limit for the frequency is 9 characters which means you cannot enter 10MHz or more using the serial command. b) The specification says that there is are four downloadable 2048 point waveforms. The serial specification does not include the protocol to do this. This is a feature I wanted for my project. 4) The included software is all in Chinese and is useless. If you only want to use this unit standalone then it is excellent value for money. If you really need to drive this unit using the serial interface then the information is incomplete.

    De FY3200S van het Chinese Feeltech levert signalen tot 24 MHz op twee volledig onafhankelijk instelbare uitgangen. Behalve de standaard signalen levert deze generator onder andere sweeps, elektrocardiogram pulsen, witte ruis, AM en FM. De ingebouwde frequentie/puls-counter is bruikbaar tot 100 MHz. Met zijn prijs van ongeveer € 50,00 is deze functiegenerator een uitstekende keuze voor het hobby-lab.

    The interface is a bit confusing at first but easy to learn. The output waveform is decent but gets distorted fairly quickly at above ~7V. The software for generating arbitrary waveforms is windows only, but will run under WINE. Tested with Kubuntu 16.04. There are also open source applications that can be used to generate the waveforms as well. All in all, it is a great price for a hobbyist level signal generator.

    This generator is absolutely suitable for hobbyist purposes. Square and triangle waves are acceptable till ~ 5Mhz. I found minor application error: if you switch to CH2 and than back to CH1, the display still shows the amplitude of CH2 untill you press the PARM button. This could be eliminated by firmware update.

    Warning:This device requires replacement power socket to 3-wire socket with ground (otherwise there is a high risk of burn). Without this alterations voltage between the generator and other laboratory equipment about 100-120V AC, which is unacceptable! Just take some of the analog calibration for precise amplitude and offset of both channels. After this little upgrade, this is a wonderful tool for their money!

    I'm basically happy with the performance of this device with just a few problems. The first two are manufacturing problems. Firstly, the lens over the display is scratched. Initially I though I'd been sent a used item but looking elsewhere it's all in new condition apart from the display, which otherwise functions correctly. Second, one of the BNC test cables supplied does not work. It seems the centre pin was pushed in when it was made and doesn't contact the socket. Lastly, the location of the data entry encoder is way too close to the output sockets. With my right hand I find that I scrape my knuckles on the BNC plugs when adjusting the unit. If you're left handed you'll have no trouble. Right-angled BNC plugs would be a better choice here. Also, the unit is very lightweight, maybe too light as it moves around when you're adjusting it. I'll be adding some weight or velcro to hold it in place. Despite all this, overall it's a good bit of test gear for the price. You do get what you paid for but there is enough excellent features in this to justify the purchase.

    Eccellente per i principianti! Il generatore fornisce buoni segnali nella sua gamma. Il software permette di controllarlo facilmente con una GUI e creare segnali.

    Consegnato per una settimana dalla Repubblica Ceca in Bulgaria! Funziona bene. Raccomando il venditore!
