Reference Level Auto Ranging

:DISPlay:WINDow:TRACe:Y[:SCALe]:LOG:RANGe:AUTO OFF|ON|0|1
:DISPlay:WINDow:TRACe:Y[:SCALe]:LOG:RANGe:AUTO?
This command enables and disables auto ranging.

Remarks:
Internally to the instrument, the reference level may change,
NOTE
depending on instrument settings and input signals present. However,
the reference level shown on the display does not change when this
command is used.

Trace Y-Axis Amplitude Scaling

:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision <rel_ampl>
:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision?
Sets the per-division display scaling for the y-axis when y-axis units are
set to amplitude units.

Trace Y-Axis Frequency Scaling

:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision:FREQuency <freq>
:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision:FREQuency?
This command sets the per-division display scaling for the y-axis,when
the y-axis units are set to frequency units, such as when looking at FM
deviation with the command [:SENSe]:DEMod:VIEW[:STATe]
OFF|ON|0|1.

With Option 1DR, Narrow Resolution Bandwidths, the
reference level is normally auto-ranged. This results in
a wider dynamic range measurement at a slower
measurement speed. Using this command to disable
auto ranging results in faster measurements and better
resolution but reduces the available dynamic range.
