FeelTech FY6600 60MHz 2-Ch VCO Function Arbitrary Waveform Signal Generator
CDaniel:
I received the microcontroller with firmware V3.1 from Feeltech , as they said that will send for free if you ask . Thx .
I will change the IC these days .
radiolistener:
that's the price for Chinese no name things... If you want guarantee and service, then buy known brands :)

I was sent a complete front panel, but with V3.1 FW which was already out of date by the time I got it and which has a known issue. The 6600 sits on the spares shelf with my Rigol DS1102E and similar gear.
I guess it's time for me to look at FY6900 reviews and see how thoroughly it's been tested. I *think* I can measure every relevant parameter now. And if not, I'll get what I need. I'm suffering from a *very* bad case of TEA syndrome.
CDaniel:
To be clear , my unit is working fine with V3.0 , I didn't ask this for a repair .
I don't think FY6900 is better if you already got FY6600 . Just minor improvements for front panel butons .
What is the isue with V3.1 ?
rhb:
The V 3.0 FW will corrupt itself completely borking the unit. It can happen at any time.

It happened to mine just after I finished adding a 3 wire connector and grounding the BNCs. I ran it for several hours, turned it off and went to bed. The next morning it looked like the photos in the link above.
It happened to another person right after they had replaced the PSU, XO, and output amps.
IIRC, the V 3.1 will corrupt the sine wave, but that is recoverable. You'd have to go back through to pages 15-20 in the thread for details.
I just watched the FY6900 video linked above. It's pretty basic. If FeelElec comes through with taking care of users with corrupted FW I'll have some very interesting posts as I have an 8560A, 8566B, 8648C, 5386A, GPSDO, 438A, 33622A and an Owon XDS2102A 12 bit DSO which will collect a 20 Mpt trace at 1 GSa/s. The Owon will let me make some *very* sophisticated analyses using Octave. I spent 30 years doing DSP in the oil industry.
