The triangle was supposed to be a sine wave.
I figure out what the problem is. It was the trigger! I posted new pictures. The traces are now thin and solid. The vertical is a little off, so I guess the next step is to do a calibration.

It seems that at least the first two pictures use the same sweep knob setting, 5 us/div. Also all 4 pictures seem to show the same distortion, a square wave like distortion, synchronous to the triangle, 8(?) times the frequency. What happens with other time base settings and other amplitudes for the same triangle frequency? What happens without cabling but input set to AC or DC (not to GND)? Can you trigger on the distorting "noise"? What happens at other sensitivities?

You have a function generator that goes to 50MHz and 100Mhz?
Your pictures are not labeled and it is not clear what your
oscilloscope's vertical deflection and sweep speed are set to so I am
not sure what I am looking at.

I posted more pictures in my album (rebelliouszombie_album). I connected the oscilloscope to the function generator using BNC adapters. The function generator is generating a sine wave at 100kHz, 50MHz, and 100MHz. You can see that the traces are very noisy.
I'll check the bandwidth limiter and the coupling and report back. Thanks.
