thank you for your answer. I used a T-piece with a 50 Ohm termination. The generator is a SDG6022X which had a different motherboard after a repair, with a SDG6052 license. I repeated the measurement with only channel 3 active and a sine wave with 4 Vpp.
At 1 KHz I measured 2 Vpp.
At 85 MHz I measured 1.4 Vpp.
At 100 MHz I measured 1.25 Vpp.
At 120 MHz I measured 1.03 Vpp.
Best regards

I have about the same results, using 1Vpp :

I've made some tests regarding High Resolution 14bit/16bit vs normal.
Signal source SDG2042X
- ch1 : ramp, 1kHz, 10mVpp, symm 50%
- ch2 : pulse, 4kHz, 3mVpp, pulse width 1us, rise edge 8.4ns
- wave combine output
HDO1074 with 50Ohm terminator, aquisition 50mV, 5ms.
Trigger single, stop, then zoom in from 50mV/5ms up to 1mV/1us
The 3mVpp/1us pulse it's very clear even in normal mode.

FFTs for the same signal, normal mode and HiRes16.
No difference.
