For linear spectrum and power spectrum measurement data, the unit of amplitude for the Y-axis scale is
set with the CALCulate:UNIT:AMPLitude command. In addition, tables E-6 -E-8 show the unit of
amplitude with transducer units (enabled with the
[SENSe:]VOLTage[:DC]:RANGe:UNIT:USER[:STATe] command).
Tables E-3 - E-8 only apply to the measurement data listed in table E-2.
