FY6900 just arrived this morning.....
BTW, have you checked for continuity between the BNC grounds and the PE pin? It's an improvement in that they're using a dedicated wire (even if it doesn't conform to the colour coding for a safety earth wire) rather than pinching one of the DC ground returns to divert past the fuse to the PE tag but only if it's not relying on a DC ground trace running, it seems to me, perilously close to what appears to be a mains current inrush limiting PTC.
If Feeltech have been lurking in these topic threads, it's just possible they may have taken inspiration from them to wire a 1 to 10 K resistor in series with earth connection.
Hi That PSU has to be the cheapest of cheap . The earth looks like it connected to the NTC .. please tell me I am wrong . .
Just love the new markings on the Cyclone .. Feelelec Pro 1941 Maybe your lucky its a Pro Fake
I am interested in whether it is the FY6900-100M model or another, and whether there are any problems with the generator-PC communication.
Really ?!?
This is all what I get there:

My advice: Flowing us with streams of words is counterproductive, believe me.
So, less writing, more reading, thinking. & checking...
Dear Customers,
I'm very apologized to I added an extra point after the link.
This is my fault, sorry again.
From a mistaken employee。
The thin grounding trace appears to still be visible were it goes over the chunk of ground plane by the DC output end. Checking the earlier pictures, this seems to have been doubled up on the top side. Is that actually the case?
I was going to suggest that such a thin trace could act as a safety fuse in the event of a full live contact from a DUT being applied to the BNC grounds but if that trace has been doubled up, that sort of protection is compromised (ie. less likely to save the black earth wire from being burned to a crisp under such a fault condition).
However, if you insert a 1 to 10 K resistor in series with the earth wire to keep mains noise and random DC offsets at bay, it can act as the safety fuse to guard against this fire risk (provided you mount the resistor clear of anything flammable).
now I see terrible things on the oscilloscope screen: a sinusoid curved inside out from below (in Sine mode) and squares full of noise on top (in Square mode). The rest of the charts are just as awful.
So here I am on a Sunday morning about to pull the trigger on a Dominty FY6900 from Amazon after several days of research on these Feeltec 68 and 6900's. And as a last minute click on this thread that caught my eye, it seems the rug was pulled out. I read a lot of this. And much of it looked good. Now I'm wondering if it isn't just the worthless Chinese crap I originally suspected, and that I'd be throwing my money away. All I wanted to do was have a little accuracy aligning my tape recorders, vintage shortwaves and vintage test equipment. I'm not running Los Alamos nuclear research over here. I figured it would likely suit me. Now its begining to look like I'd be better off peeling off $125 in cash and walking to the dumpster and throw it in.

Go for a UNI-T 962 they are about the same money and they work fine out the box . They may not be up-to NASA specs . But dam close .
There is no jitter and it uses good qual chips .

Thank you. I will check it out, but wth due suspicion over anything coming from China. I have a basic resentment of sending a penny there. I have also checked out an HP 8111a from the 1980's that I can get in unknown condition (but actually reparable). I'm becoming research-weary.
