To ensure proper coupling of your input signals to the oscilloscope, consider the
following points when you use 50 W coupling with any channel:
H The oscilloscope does not accurately display frequencies under 200 kHz if
AC coupling is selected.
H The oscilloscope reduces the maximum volts/division setting for the channel
to 1 V from 10 V (to 10 V from 100 V with a X10 probe attached), since
input amplitudes appropriate for the higher settings would overload the
50 W input.
