Distance
You can also manually set a distance to be measured by entering start and stop distances.
The maximum measurable distance is dependent on the frequency you set. You can set any
values within the maximum measurable distance, but optimum resolution is achieved when
you set the distance same as the maximum measurable distance, which is displayed in the
measurement setting information bar at the bottom of the measurement screen.

Amplitude
You can set maximum and minimum values of the Y-scale manually by setting the Top and
Bottom amplitudes or restore the instrument's default full scale defined for each
measurement mode. You can also optimize the Y-scale automatically so that an entire trace
can be displayed on the measurement chart. Adjusting Y-scale does not affect calibration
status.
