Here is 100 Hz 6 Vpp setting for sine and triangle waveform captured on 8-bit oscilloscope at 1 GS/s.
radiolistener:
100 Hz 4 Vpp sine and triangle wave captured with sound card at 192 kHz
Also added zoom for triangle wave at zero crossing position.
And sine spectrum.
maxwell3e10:
Having no external clock reference and 8192 waveform points puts it in the same class as FY6600

Despite the size and the toy-like appearance, this will get you a much more mature instrument which can be considered to be the entry into the professional segment. Have a look here for a set of teardown photos of my DG811. It becomes directly obvious that this generator plays in a different league.

yes indeed different league... your DG811 is 20MHz @ $300. this Juntek is 80MHz @ $200... i guess to make apple to apple comparison with Juntek (or UTG962), Rigol DG4062 60MHz AWG ($800+) is better suited, imho...

Just looked at some US sellers of this fine instrument...over $200??? This thing is really a piece of junk. Might be worth $50. My recommendation to anyone looking at these is save your money and get an actual good quality signal generator from a reputable brand.

What are you basing this revelation on? have you even used one, or seen one in person ?
I have used one, and I like it, it is a LOT better than some of the others I have tried, and for the money I actually think it is pretty good, it isn't just a function generator, or an ARB, but a SIGNAL GENERATOR.
Not everyone can afford a Keysight, or Rohde & Schwarz etc. that is why there are difference classes of instrument to suit different budgets, for the price class this is in it is excellent.

I once had something very similar, and it was a total piece of crap that ended up croaking for no obvious reason (probably the shitty SMPS, not worth fixing). It's not even heavy enough to be a door stop. Notice that I didn't exclude Rigol or Siglent equipment. There also used.

can you recommend a good brand name that can go 60-80MHz at ~$200?
btw, here's flatness of my UTG962 (up to 60MHz) taken from some random project... (yellow synch signal, cyan sweep input (UTG962 output), deep blue is DUT sweep output purple NA). happy buy so far, i'm sorry for your experience, it happened sometimes...

Sure. If you will use it as-is. I know of few to none private users or small businesses who won't consider hacking. Sorry, but IMO your point is ridiculous.
