The analyzer determines the default Y-axis unit based upon the specified measurement data and trace
coordinate system. Table E-1 lists these default Y-axis units.
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.
