Hi,
Send Dave an unit for TEARDOWN!

[Ysjoelfir]

If you are very interest it, you can contact us on this forum or email address.

I am very interested. You can send me a free sample for review. 

[Adrian_Arg.]

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.

[ArsenioDev]

Still no firmware upgrades or nice solid linear power supplies, Won't be getting these, my prior generation will do fine.

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 FY6600 https://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. 

[don.r]

Why 3 channels? Seems rather niche. How about better quality case and PSU? How about better user interface and customer support? Seems to me you should be spending time fixing the current products rather than coming up with new ones no one asked for. Just my opinion.

[Roger Need]

Has anyone else noticed that this company is FeelElec not Feeltech.   Looks like a corporate name change on some products but same old stuff.  Here is the new website...  http://feelelec.cn/

$530 for a sig gen from a company with a track record of poor design, major quality control issues and zero technical support? "Tell 'Im he's dreamin".

[CDaniel]

I doubt they resolved the issues from older designs , just 3 channels ... for what ?

[Noy]

530$?? Banggood says 147$ for 60M version.
But yes, show us a teardown / pictures of the PCB and power supply . We will judge...

I saw on banggood it looks like they installed a fan now in the backside.

[nctnico]

From what I have seen from a FY6900 teardown they pretty much got all the issues solved.

LOL! The price keeps dropping. Yesterday it was CAD$240 and now it is under CAD$200. I can't see $50 worth of upgrades here over the FY6900.

[Ysjoelfir]

It's interesting to see that FeelWhatever doesn't even bother to comment to any of our posts.

[Adrian_Arg.]

It's interesting to see that FeelWhatever doesn't even bother to comment to any of our posts.

How do you want FeelWhatever to comment?
1- they added a $ 4.00 cooler
2- Now it is gray.
3- The BNC frequency counter, now it is a third output channel.
4- a model got two buttons
5- Continue without firmware support, the only way is to buy model by model, so there is no table that can withstand so many generators.
6- It has no post sales support, never had it.
7- 60% of the problems were solved by members of the forum, to whom they did not even give thanks.

that if what they improved and much are the prices, from US $ 180 to US $ 360, they are crazy, they think they are cell phones that people change because they do.

When the FY6600 was ruined, I sent more than 30 mail to the support "", they never answered me, I bought the FY6900 because I need one for hobby, and small projects, since the siglent and the rigol were out of budget for me.

[FeelElec]

Dear Customers,
Maybe there is a misunderstanding. The price of our product is 108 USD -241 USD. I'm sorry that I didn't adjust the price in time due to my mistake, but now the price of the AliExpress has been adjusted.
FY8300-10Mhz  108 USD.
FY8300-30Mhz  150.28 USD
FY8300S-20Mhz  150.28 USD
FY8300S-60Mhz  241.20 USD

I'm very apologized that this mistake.

Hang on. So you bought one, it died and you asked for support then didn't get any, so you bought another one from the same company ?!?
No wonder they keep pumping out rubbish!

This toys that don't complies with any security and EMC compliance law
 at that prices is a joke , really !
Fortunately, there is others serious chinese manufacturer...

correct, the human is the only animal that stumbles twice or more with the same stone , but this is the FY6900 is nice as he steps on papers, I also like the buttons and the shape.

FeelElec, only responds to the cost of money, then for everything else has no answers, at least those of Siglent, rigol, Keysight, etc. They bother to answer the questions, and the rigol solved my problem with the ds1054z, they have a lot to learn from the competition.

This price is Rigol territory and you don't have the stones to compete here.

Well it is not like Rigol and Siglent have been acting much better. 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.

[Kleinstein]

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.

[FeelElec]

Wrong!

Dear Customer,
Please check the price on our store.

[Adrian_Arg.]

Ok friend FeelElec, they modified the prices, worry the free shipping, only you see it, it is about the only thing that you comment only money, now improvements on the equipment nothing at all, only that it has three channels, when you will launch a team in the which you are launching firmware correcting errors, or this is the error and failsafe equipment.

Well, it's at least cheaper than altium?

[StillTrying]

Why would they come up with a 3 channel FG, were they inundated with requests for one.

[beanflying]

+50% Channels and flog it for 200% with the same backup and kwality = more profit.

Or am I just a cynic 

[StillTrying]

+50% Channels and flog it for 200% with the same backup and kwality = more profit.

I'd pay extra for only 2 channels and something else such as a fast pulse output instead.

[ZhuraYuk]

Just bought 6900 for 86$ with free international shipping. It is other brand but PCB inside is identical and has feeltec logo.
https://aliexpress.com/item/33047509412.html

[excitedbox]

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.

[ZhuraYuk]

Hantek HDG2000B is quite simialr and can be hacked from 30MHz to  100Mhz for free. But the lowest price that I saw is 180$ without shipping. At recent ebay 20% off  I was able to get it for 144$ but still with shipping it is almost twice the price off 6900.

[CDaniel]

In the first place Fy6900 has some issues , just to mention shitty power supply and jitter for square wave .
So , if Fy8300 is the same could have 10 channels and not worth the money . It is just a toy not a real generator .

[excitedbox]

Wow for $144 I would have bought that. With the conversion to euros it would only be 20 more than the fy6900. 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.

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.

[Grandchuck]

When you add a 50 Ohm load to a source with an impedance of 50 Ohms, the load voltage drops to 1/2.

[bean_dip]

Right, I guess I mis-stated my issue. Every other function generator I've used was calibrated to display the voltage delivered into a 50 Ohm load meaning it would display double the voltage into a 1 MOhm load. This one is calibrated the opposite.

Sorry if I misspoke earlier.

[Grandchuck]

Yes I can see how that is misleading.  One of the 'gothchas' in low-end stuff, I suppose?

[nctnico]

Right, I guess I mis-stated my issue. Every other function generator I've used was calibrated to display the voltage delivered into a 50 Ohm load meaning it would display double the voltage into a 1 MOhm load. This one is calibrated the opposite.

On modern functions generators you can usually select what the display should say (loaded with 50 Ohm or a high impedance load). Perhaps there is such a setting on this generator too.

[bean_dip]

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.

[mnsergey]

Good 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.

[kiklhorn]

Just arrived strangely labeled device.
Test planned to next week.

[bingo600]

Just got a FY 8300-S 60MHz from Banggood $130 incl VAT + Ship.

I still have to turn it on ....   
Quite busy atm.

But nice price.
And 30 min later ... Not available at that price.

[nata.loko]

Has anyone managed to get "uplink" mode working? Bought 2 units because I needed 6 channels but will have to return them if the function doesn't work as advertised

[ByteRock]

Long time lurker first time poster

I picked up a FeelElec 6800 two years ago  and quickly blew the front end when was playing about with some high voltage valve gear,  (yes I know I should of used a blocking cap oh well live and learn)

Anyway I managed to fix it  you can see the full story here





In case someone has similar problems. 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.

[ledtester]

Thanks for making these videos. Your story in the third video about Chinese fabs having the green light to make non-exportable "clones" of authentic parts was very interesting.

https://youtu.be/EgO6vKxOyRU?t=2m30s

So are the THS3002I chips in the Feeltech devices indistinguishable from the ones you would get from Mouser or Digikey?

Just to advise that FY8300 V1.3.7 firmware is availble from the manufacturer via download link (you have to request it). This contains the new firmware, loader application and word doc instructions.

This fixes a number of issues that I had in a recently delivered unit that had V 1.3.4 including the generator channels not restarting after zero frequency setting.

Could you be a bit more specific about how2 request ?
Or maybe share the FW + DOC  (If for 8300S)

Do you update via USB or

Has anyone managed to get the firmware and loader from the manufacturer for the FY8300S?
Has anyone extracted the firmware from the onboard EEPROM chip? I have a bricked unit that I would like to restore but so far no response from repeated requests to the manufacturer.
