My perspective for comparison here is the FY6600 which I also own. The good news is that the 4.5ns square wave jitter so noticeable at 9MHz and 11MHz is gone from square waves and related waveforms like CMOS that are a DC level shift from a squarewave. However, the 4.5ns jitter is still present in most other waveforms that have a fast rise or fall like ramps. Sine waves from 60Mhz to 100MHz have increasing amplitude perturbations so that at 100MHz you have significantly distorted sine waves. On the spectrum analyzer at higher frequencies there are what I would call close in sidebands on the FY6900 100MHz. Amplitude ripple at 60MHz is slightly worse on the FY6900 than the FY6600 and severe at 100MHz. Sidebands on the FY6600 are farther away from the center frequency at both 60MHz and 100MHz. So the big improvement is with square wave jitter. I am not sure how usefull the FY6900 will be at 100MHz.

I liked it quite, arrived quite fast, less than two weeks, I am quite satisfied! Pretty much everything from the bleacher was bought at Banggood...super satisfied!

Gostei bastante, chegou bem rápido, menos de duas semanas, estou bastante satisfeito! praticamente tudo da bancada foi comprado na Banggood... super satisfeito!

I'm using the signal generator in my hobby, to experiment in the field of audio electronics. The product revealed a fairly easy and straightforward user interface. In about a month of use I have not encountered any reliability problems and it effectively fulfills the purposes for which I purchased it.
