By the way for 190 the Hantek does 40 Mhz for all waveforms not just sine and 10MHZ for the others like the fy8300 does.

Hantek HDG2000B is quite simialr and can be hacked from 30MHz to  100Mhz for free. But the lowest price that I saw is 180$ without shipping. At recent ebay 20% off  I was able to get it for 144$ but still with shipping it is almost twice the price off 6900.

Do you care to write a review about it?

So , if Fy8300 is the same could have 10 channels and not worth the money . It is just a toy not a real generator .

Dear Customer,
Is the FY6900 you purchased having problems with power supply and square wave jitter?
If have questions, you can contact us. And we will resolve the question.

I just got mine (ordered from Ebay as a KKMoon Re-Badge due to payment options).  If anyone has any questions about it, let me know and I'll do my best to test what I can on it.  I'm just building a demonstration lab for my classroom, so not super-well equipped yet, but I'll try.

I know it's just one step above a toy and not for serious work, but I mostly just wanted it to do demonstrations in the classroom of what 3-phase power, AC vs DC, and PWM outputs from Variable Frequency Drives look like.  Doesn't have to be horribly technically accurate, just good representations.

One thing I can say that I've noticed so far is that the output power will NOT deliver the rated voltage into a 50 Ohm load.  According to the spec, the output impedance is 50 Ohm +/-10%, and the output voltage is +/-12V at frequencies below 20 MHz and +/-2.5V above 20 MHz.  I tried terminating the generator into a 50 Ohm load on my scope with a BNC Tee and Terminating Resistor, but it generated exactly half the peak-peak voltage you set in the generator menu.  With the generator feeding directly into the 1 MOhm scope input, it's much closer (set to 12V p-p I get 12.2V - 12.5V).

For reference, mine is the 10 MHz model.
