A user-defined unit label can be entered.
Example:
The output level U
0dBspl
which is output at a sound pressure of
0 dBspl (spl = sound pressure level) is specified for high-quality
microphones.
If the measured microphone output level is displayed in the refer-
enced unit dBr and entered for the reference value U
0dBspl
, the level
displayed on the R&S UPP will be in dBr, but corresponds to the
sound pressure in dBspl. An axis labeling using the unit dBspl would
be desirable in the graphical display. To allow this, the unit label can
be changed from dBr to dBspl.

Engineering
Conversion of the Trace A- or Trace B-related cursor and scaling values in the graphi-
cal display by a factor of 1000.
This parameter field cannot be accessed if a dB or % unit is selected in the "Unit Funct
Track" or "Unit" parameter field above since these units do not have an engineering
function.
