Here are input sensitivity ranges:
1 MΩ; 500 µV/div to 10 V/div in a 1-2-5 sequence
50 Ω: 500 µV/div to 1 V/div in a 1-2-5 sequence.
Note: 500 μV/div is a 2X digital zoom of 1 mV/div or a 4x digital zoom of 2 mV/div, depending on the instrument bandwidth configuration.
Also a regarding a 1-2-5 sequence, following patterns helps explain what a a 1-2-5 sequence is: 1mV,2mV,5mv,10mV,20mV,50mV, 100mV, 200mV, 500mV, 1V, 2V, 5V, 10V /div.
