Ref Offset
Assign an offset to the reference level to compensate for gains or losses generated
between the device under measurement and the analyzer.
Key Points:
 The change of this value changes both the reference level readout and the
amplitude readout of the marker; but does not impact the position of the
curve on the screen.
 You can modify this parameter using the numeric keys. For more details,
please refer to "Parameter Setting".
Auto Range
Adjust the amplitude parameters within the current span range automatically in
order to display the whole signal optimally on the screen.
