--- Quote from: egonotto on December 14, 2023, 02:43:12 am ---Hello, 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 egonotto --- End quote --- I have about the same results, using 1Vpp : https://www.eevblog.com/forum/testgear/hacking-the-hdo1khdo4k-rigol-12-bit-scope/msg5207655/#msg5207655 |

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. pictures for normal mode: |

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