content: I also signed up with Ysjoelfir, looking at the price of the product, it must have improved a lot, since I would add a few dollars I would go for a siglent or rigol, since I do not think that in quality and guarantee and support the fy8300 approaches these products , also until today you do not release firmware update, have left many customers hung with equipment for use of paperweight (I precisely have an FY6600), it seems to me that they have not changed or improved so much to have prices so high.PD: I acquired a FY6900 of 60Mhz, it works quite well, but the sinewave after 30Mhz no longer behaved the best, a friend offered to buy it, sold it, and a few days ago I received the FY6900 of 20 Mhz, more than enough for my purposes and leaving me a small profit, the day you launch firmware updates, and have serious support, they will begin to be a responsible and reliable company. For now just for hoobista like me.

content: FeelElec:Unless you and your company assures the eevblog community that you have done due diligence in upgrading your new product from the FY6*** series, you will have a hard time selling a new signal generator here. Seriously, have some of your engineers read the thread on this site about the FY6600https://www.eevblog.com/forum/testgear/feeltech-fy6600-60mhz-2-ch-vco-function-arbitrary-waveform-signal-generator/all 86 pages; then report back on all of the improvements made to your new product. There is a lot of free engineering in this thread; all you have to do is utilize it.Marketing test equipment isn’t like marketing smart phones. You state it is an innovative product which for many of the people on this forum only means more bugs and problems as we’ve learned from your previous products.

If a product doesn't sell well enough they simply won't fix the firmware. A couple of years ago I've -more or less- binned a brand new Siglent scope because it was utterly useless due to poor firmware. I lost over 1700 euro on that (no returns accepted). OTOH the FeelElec devices are cheap enough not to get severely burned and two bad units are still way cheaper than anything else.

content: The prices seem to vary quite a bit. Going quite high in some places and even lower in others. This is a little odd - though for a new product there may also be buggy early versions around and who knows what mistakes are made calculating prices. A high price could be a sign of low inventory for some dealers. Sometimes they just set up the Ebay price instead of taking out a product - not expecting to sell as they have non available.From the description the new 8300 is essentially a 3 channel version of the 6900 or 6600.With a history of buggy software, one may consider waiting a little with the new model, unless one really needs 3 channels.The cheap Rigol version is still more expensive and it's 2 nd channel is limited resolution. So at least from the paper specs cheap generators don't look that bad. The main point is if the firmware actually works or one can expect to get updates with fixes. So a review showing that it actually works could really help.

content: My 6900 has been stopped by german customs twice already. I ordered over 3 months ago from ebay and I just had the seller give me a refund 2 days ago because It just won´t make it through customs.Also I was negotiating with feel elec to redo their website for a free signal gen which is over a 90% rebate over my normal fee. Just as we were about to make a deal they backed out and decided to do it themselves. They did do some minor changes but In a world where any company can have the image of the big players they obviously don´t value customers opinions. I don´t care about not getting a free unit because 2 hours of work pays for one and I had already ordered the one I just got refunded. Just think it is weird that someone would care so little about their image that they would turn down a deal like that. If Everything else was the same and I was to look at their website and Rigol´s, Keysight´s, etc I would buy from their competition just as you would hire someone in a suit over an unwashed hobo.By the way for 190 the Hantek does 40 Mhz for all waveforms not just sine and 10MHZ for the others like the fy8300 does.

I paid 104 Euros shipped but since customs keeps snatching it I would have been better off getting a more expensive unit and not wasting 3 months+. If this one I ordered from Spain doesn´t show up soon I will go that route. It has been 3 days and still no shipping confirmation.

content: I just got mine (ordered from Ebay as a KKMoon Re-Badge due to payment options). If anyone has any questions about it, let me know and I'll do my best to test what I can on it. I'm just building a demonstration lab for my classroom, so not super-well equipped yet, but I'll try.I know it's just one step above a toy and not for serious work, but I mostly just wanted it to do demonstrations in the classroom of what 3-phase power, AC vs DC, and PWM outputs from Variable Frequency Drives look like. Doesn't have to be horribly technically accurate, just good representations.One thing I can say that I've noticed so far is that the output power will NOT deliver the rated voltage into a 50 Ohm load. According to the spec, the output impedance is 50 Ohm +/-10%, and the output voltage is +/-12V at frequencies below 20 MHz and +/-2.5V above 20 MHz. I tried terminating the generator into a 50 Ohm load on my scope with a BNC Tee and Terminating Resistor, but it generated exactly half the peak-peak voltage you set in the generator menu. With the generator feeding directly into the 1 MOhm scope input, it's much closer (set to 12V p-p I get 12.2V - 12.5V).For reference, mine is the 10 MHz model.

content: I didn't see anything in the user manual about changing the scaling, but I haven't played with all the buttons yet. I'm not super worried about it, just caught me off guard.Another thing I've noticed that I'm trying to quantify is that the frequency seems to jump around a decent amount whenever a button is pressed. And I don't mean controls that relate to the channel parameters, but any button at all. Another low-end gotcha, I'm sure, but worth noting.Again, I'm not complaining because it works for what I need which was three moderately accurate wave representations for demonstrations on a scope.

content: to bean_dipGood time of day.Please tell me, in the 8300S version, in the mode with three outputs, whether it is possible TO immediately get a PWM modulated by these sinuses(20-400)Hz on three outputs. This is necessary for me to control the drivers of the three phase experimental inverter, directly from the generator, bypassing unnecessary conversion in the PWM controller.P.S. As I understand, You are the only owner of FY8300S in this topic. Do you plan to run tests for the presence, and level of the jitter, and consider, and test its internal power supply? This will put an end to the question - what is the difference between 8300 and 6900, whether only three outputs, or they have made corrections to the problems known to many that I described above.P.P.S. Sorry, I was inattentive. You have version 8300, without the letter "S". Therefore, the first part of the question is removed.

It is fixable at least back to the RLCR networkds.In the end the only real problem was finding a replacement for that mystery 30021/3002 chip. Seems a THS3092 does the trick though it does heat up allot at high voltage. The bonus is all non Sine waves over 5MHz are much better with the 3092 might swap the other two out someday.Cheers and thanks for all the good posts.
