In my FY 6900-60, firmware of  flash FPGA  broke. I wrote to FeelElec  - I received no answer. I tried the firmware from  FY 6600 - it does not work. Firmware of control panel 1.3.1   What to do? :-[

FY6900-60M
For anyone keeping track of the variants, I received a FY6900 today (Banggood) with:
* 5V power supply board V1.32
* main board V3.31 with  "AN_EG4D20EG176"
* front board V2.2
* firmware V1.5.3

Also got mine from Banggood (EU store) though in early 2020 when they were clearing EU-stock at a heavy discount. [FY6900/60MHz]

Generally just use it with power bank or the scopes 5V USB out (for most use cases) as the wiring from the PSU, seems to center around 5V on my unit.

// Anybody fitted batteries in these units, with a crude charge & buck/boost circuit?


[PD3.1 140watt in/out pr socket powerbank, but can run from more or less' any power bank as the wattage draw is quite low]


Choked that annoying squeaker for a more pleasant "I got it" feedback, instead of toggling it off.


btw, did anybody have rise&fall adjustment on any of the FY6900 software versions, as seen on the FY6800.?

// 4:17 rise/falltime adjustment by double pressing the duty.??

Hi
Does anyone know the 40MHz variant FY6900-40M?
Is it from Feeltech or is this something else?
It does not exist on the Feeltech website.
What is that?

FWIW, I received my FeelElec FY6900-60M and its cables from Amazon at a bargain price (119 € delivered)
Not opened yet, but it boots up and links immediatly to the PC.

Here were the steps I took:

- PC Software downloaded from Feeltech website (see replies above to find the link).
- RUN IT AS ADMINISTRATOR on Win11 !   Do NOT connect the FY6900 to the PC yet.
- PC SW is version 6.3.  It's rather buggy.....    Go to Help -> Update -> OK and update to 6.5
- Run version PC SW 6.5 as admnistrator
- Only then, connect the FY6900 to the PC  --->  It connects without any problem
- Firmware version is 1.5.3, I do not know if a newer version exists and where to get it

I will make some basic tests (see if both outputs and inputs are working correctly)

Three small modifications I will also do immediatly:
- Solve the PE wire issue
- Add a 12V fan
- Put a heatsink on the LDO's and maybe the FPGA

One question about the PSU and the PE issue:

In my house (which dates back to the '70s), there is no PE in my lab.   And I do not use an isolation transfo either.

Is there a risk of frying my equipment (say my 'scope) if I connect it directly to the FY6900 ?  :-BROKE

If so, what are your recommandations (given that installing a PE line would be a LOT of work including breaking walls on two levels, which I'd rather like to avoid....) ?

I've finished to read the complete thread (very difficult to sort things out because of a lot of off-topic, - but very interesting anyway - posts).


To get rid of the isolation problems and HF SMPS induced noise, I intend to replace the 5 V PSU with a simple linear one.
And a good fan, of course....

What power do I have to foresee ?
Does anyone have measured the current drawn on the 5 V line ?

.....

As mentioned above my FY6900 seems to rely on 5volt from its PSU board, as can be seen in #678 above' with 5V and G,G, lines.
If all FY6900 revisions is like that and dont dig into +/- 12v lines from their PSU boards, I cant say, as its been rebadge under tons of names, and only got the one above that is around 3 to 4 years old.
- been running my unit from my Micsig scopes 5V USB2 socket, and havent notice any issues, even though that socket cant supply a lot of current.
from the pictures in #678 post and what the powerbanks display reads, it seems to consume around 2.1W in just idle, though havent checked what it peaks at, at various setup & waveforms.

I assume (Worst case scenario) that if the output of a signal 20 Vpp is put into a 50  \$\Omega\$ load, this will draw 0.4 A.   Two outputs => 0.8 A

If I aim for a 5 V - 2 A, it should suffice....  that is my initial guess.

However, my motivation to replace the PSU with a linear one is mainly a noise concern.   
I have seen designs based on the venerable LM723 that deliver 0.5 mVpp of noise....
Compared to even a good MeanWell that at least outputs 20 mVpp....

Strangely, that argument (of noise) has not been greatly debated....

Any ideas or experiments on that subject ?

My FY6900 (60M) broken after very few minutes of use.
Channel 1 is conpletely dead. Channel 2 has some life to it, but sine wave is not complete and after 6V amplitude it dies too.

Anyone else had similar problems? Is there anything I can do to fix this?

I realized that bending little bit the whole case fixes the channel 2. I know it sound crazy but it is true. I have opened the case and if waveform is nonsense on channel 2, then I just press down the bottom of the case (next to the board) and channel 2 gets fixed. Loose connection somewhere?

Further investigation got me to realize that this part was very loose (barely attached at all). I was touching it very gently with my finger just to check everything is in place and this part came loose. Im not sure what part is this or is it any way related to the misbehaviour of my device. Can anyone identify what is this and what is the function of it? Im talking about this screw head looking part.

SMD Potentiometer. What broke off is the wiper. Should be an easy repair (replace with another pot of same resistance value).

BTW looks as if it's been replaced before due to the excess solder flux around the pot.

Best,

Thx mate. Can this one buggy SMD potentiometer explain channel 1 being conpletely dead and weird behaviour on channel 2?

Edit:
According to this video, the broken pot should affect only to channel 2.



So, something else must also be broken.

Hi,
I have a FY6900-60M purchased 2 years ago.
I read here that current fw is 1.5.3. Mine has 1.4, and the oficial and ugly app (Vers 6.5) shows that latest version is 1.3  while installed version is 1.4, crazy  :--
My board is V2.1 (5V only). The FG works well for me, no issues, so no real need to update it.
Is it possible to update the device or is something depending on the board hw level and cannot be upgraded?
Any clue? Thanks in advance!!
J. Alonso

There is a version of the software that was brought to update the software and firmware, but as expected, these Chinese ones from the FY6900, not useless ones, so it never worked, so forget about it if you expect help from the manufacturers.

in spanish
hay una version del softwareque trajo para actualizar el soft y el firmware, pero como es de esperar estos chinos los del FY6900, no unos inutiles, entonces nunca funciono, asi que olvidate si esperas de los fabricantes una ayuda.

Has anyone tested a new software V7.8   for  PC? When trying to update firmware it gives a mistake.

There is only the 6.5 version on the official website
FNIRSI 1013D Always provide a picture or video with the problem where the parameters of the oscilloscope are visible, and a picture of the diagnostic screen with the values.

Yes, I already noticed, but first I logically downloaded the package directly from the given device and there is 6.5. all in all, they have some mess in it.

It says that it cannot connect to the Internet

I have sent you 2 emails asking about your PC software to control this unit which does not control the frequency. No one has answered. I eventually obtained the latest software which worked (which you only do if you turn off your antivirus). I monitored the TTL output with a scope with serial  decode to find the difference between you old PC program & the new one. Unfortunately your instructions do not show the change.  A disappointing waste of time. You can't complain about the service because there isn't any !!!!! If I had not already spent a lot of time on my control program, I probably would have moved to Juntek.

hello. For me, the latest version of the software v7.8 does not work, the Windows control tab does not work, whatever option I choose does not work, the other tabs do work, there is no new firmware for the FY6900 either, I am left at 1.3
