For linear spectrum and power spectrum measurement data, the Y-axis vertical unit is set with the
CALCulate:UNIT:VOLTage command. See table E-2 for valid Y-axis vertical units. An "X" indicates a
valid selection.
Units for data registers (D[1|2 . . . |8] ) and waterfall registers (W[1|2| . . . |8]) are dependent upon the type
of measurement data stored in the register. See the appropriate measurement data row for valid unit
selections.
The CALCulate:UNIT:VOLTage command is only valid for the measurement data listed in the table. It
is not valid for any other types of measurement data. If you do not know the current measurement data
selection, send the query, CALCulate[1|2]:FEED?.
