Couplings When "Auto Scaling" on page 1563 is ON, this value is automatically determined by the measurement
result. If you set a value manually, "Auto Scaling" on page 1563 automatically changes to OFF

Couplings Coupled to Scale/Div as follows
Scale Range = Scale/Div * 10 (number of divisions)
When you change this value, Auto Scaling automatically changes to OFF

Y Axis Unit
Displays a dropdown menu that enables you to change the vertical (Y) axis
amplitude unit. This setting affects how the data is read over the remote interface.
When using the remote interface, only numerical values are returned, so you must
know what the Y Axis Unit is to interpret the results. This is described in more detail
in "Amplitude Data Query and Y Axis Unit" on page 1559 below.
For measurements that support both Log and Lin scales, the instrument retains the
entered Y Axis Unit separately for both Log and Lin amplitude Display Scales. For
example, if Display Scale has been set to Log, and you set Y Axis Unit to dBm,
pressing Display Scale (Log) sets the Y Axis Unit to dBm. If Display Scale has been
