:FUNCtion:REFerence
(see page 530)
Command Syntax :FUNCtion:REFerence <level>
<level> ::= the current reference level in NR3 format.
The range of legal values is from - 400.0 dBV to +400.0 dBV depending on
the current :FUNCtion:RANGe value. If you set the reference level to a
value outside of the legal range, it is automatically set to the nearest legal
value.
The :FUNCtion:REFerence command is only used when an FFT (Fast
Fourier Transform) operation is selected. The :FUNCtion:REFerence
command sets the reference level represented by center screen.
Query Syntax :FUNCtion:REFerence?
The :FUNCtion:REFerence? query returns the current reference level in
dBV.
Return Format <level><NL>
<level> ::= the current reference level in NR3 format.
