Sorry but that statement is :bullshit: in spite of the attempted humour. The FY6600 was a flawed product certainly and some had failures but a lot more didn't and it represents great value. There has been a lot more paid for products with much worse performance and issues. The main failing was Feeltech themselves putting up the shutters and not resolving or providing a mechanisim to fix those issues of some customers (firmware support).
Best not to add to much detail on the FY6800 here as there is already several threads with that in the title so it will get lost over time.

FY66 is not bad? From what i learned form this thread the firmware seams to freeze for some people making the unit non working while FY as you said your self dont provide any means at all to fix this nor allowing a third part, which inhibits my self to buy a FY66 and as such i consider that a failed product. Or have i missed /misinterpreted something else what you said is infact contradictory :bullshit:?
On that base i have serious constraints into buying a FY68. How do i know the FY68 is not flawed with problems? :-//
Other people in this thread have said "dont by a FY product until they fix FY66", well thats a fair statement i think.
However i do concur that FY68 deserves its own thread i hope will just contain 1 page not 71 as FY66 got! ;)

I ordered some samples from ti for the ths3491. Hope the advertising of "more headroom" and so on is true. Maybe then there is no need to build a new power supply. Even If a linear one would be great.
Also i will check If its possible to twaek the original Power supply to 13-14 V maybe some other feedback resistors?
Fojnd the same txco and ordered it (directly from Ali).
Need to Check the supply from it (12V to high and 5V too Low.) and If the 5V Out is ok or maybe i have to adjust it to 3.3V?
I think it is an easier way instead of using a pll Chip. And i don't have a gpsdo so i don't need an external clock in.
Maybe i will use a si5351A? But i think it is even more worse than the original Crystal?

So i tried to find your 50 Ohm issue.
For me IT IS not totally clear for me what i should See or mit See. Can you explain it a Bit more? I looked at the output with 0.6 and 0.5 Amplitude. And checked it with 50 Ohm termination and without..
Only issue i swa ist a small dc offset as Soon as i Switch the Mains on... Can i recalibrate it?

I'd imagine motion sickness sufferers would have a hard time trying to watch that video. Why the hell didn't he fix the rocky table before recording his review? I'll often watch repeat videos to pick out stuff I may have missed the first (or even second) time round but not this one.

i did that on purpose, just for people like you ;D
Ive got 3 of the fy6800 units now, two of which i bought broken. 20, 30 and 60mhz model all of them share the same internals (v1.7 board) but different software-config.
one was a easy fix, just a connector was unplugged
the other one had its Powersupply break. (IC blow, main capacitor a bit on the low side, pcb cracked. Fuse(c)apple inc intact .
the numbers have been rubbed off but i figured out its a THX203H IC
before i order a buch of them, id rather make myself a drop-in replacement pcb with linear regulators
time for somone to write a custom firmware, id rather need a sweep trigger than a sync/uplink IO

I found that loading a file length @ 8193 prevents the run time shut down error.
Here is what I did:
1. generate 8192 length .csv
2. Rename it to .fy; press the waveform window tab
3. Go to file at top of main window; press open
4. Open your file (length 8192)
5. The "extraction data" window opens.
6. Click the "open file" button in the extraction window
7. Your waveform should be visible in the extraction window.
8. There will be several dialog boxes open in the extraction window data length, fetch length, start, end.
9. Enter 8193 into the "end" dialog box
10. Your waveform will now be visible in the waveform window.
11. Upload to your desired memory location
12 Your waveform will be visible on your oscilloscope.
