Newly acquired signal generator ET3360C disassembly test

[clement]

I received the signal generator today. Unlike other white shells, it has a black appearance. The shell is made of plastic material, and the product is very light, and the waveform is not particularly good. So I took it apart and found that there are many relays on the circuit board, and there are two unknown connecting wires. It feels like a repaired product, which completely does not meet my expectations.

The soldered wires seem to be normal.
Someone posted a photo of the same board on Banggood.



The sine wave looks weird.
Can the oscilloscope keep up? Amplitude modulation?

Using "Keysight Technologies" Bandwidth 1G，There will be relatively high peaks in the test sine wave output, I am worried that it will burn out my equipment, and I am ready to return it
