2.1.3 AMPT
Sets the amplitude parameters of the analyzer. Through these parameters, signals
under measurement can be displayed at an optimal view with minimum error.
2.1.3.1 Auto Scale
This setting enables the readout resolution of the current Y-axis to be the maximum
possible on condition that the whole signal is within the screen. When enabled, the
system sets the reference level automatically in order to place the peak of signal
within the topmost grip.
