Autoscale Automatically adjusts the Y-axis to comfortably fit the
Minimum and Maximum amplitude of the trace on the screen.
— Autoscale All Autoscales all of the traces on the screen, useful only
for multi-trace configurations.

— Scale Manually enter a scale per division to view specific
areas of the trace.
— Ref Level Manually set the value of the reference line.

Magnitude Offset
Magnitude Offset allows you to offset the magnitude (not phase) data by a
fixed and/ or sloped value in dB. If the display format is Linear Magnitude or
Real (unitless), the conversion from dB is performed and the correct amount of
offset is implemented.
The Magnitude offset setting affects only the active trace.
