I have found two bugs so far.
Unfortunately, I don't use it much, the FY6800 is often enough for me.
One is when the dolphinfish attack, the device becomes unusable.
I don't know what's causing it, but I can't change the setting of channel 1, only channel 2, but it has no output, it responds to the buttons. This is the
second time it has come up.
Third, only now at the counter.
The other is that at and around 1Hz square wave there is a small sine wave, the location and frequency of which depends on the frequency.
and the duty must be between 20-95%.
It can also be found for the pulse, but only if the trailing is 3.0ns.
It doesn't do it at 3.1ns.
Due to the lack of memory, it is not visible, but I measure it as a 312.5Mhz with the DHO924. I don't have a faster scope.
