:FUNCtion:CENTer
(see page 530)
Command Syntax :FUNCtion:CENTer <frequency>
<frequency> ::= the current center frequency in NR3 format. The range
of legal values is from 0 Hz to 25 GHz.
The :FUNCtion:CENTer command sets the center frequency when FFT
(Fast Fourier Transform) is selected.
Query Syntax :FUNCtion:CENTer?
The :FUNCtion:CENTer? query returns the current center frequency in
Hertz.
Return Format <frequency><NL>

NOTE After a *RST (Reset) or :AUToscale command, the values returned by the
:FUNCtion:CENTer? and :FUNCtion:SPAN? queries depend on the current :TIMebase:RANGe
value. Once you change either the :FUNCtion:CENTer or :FUNCtion:SPAN value, they no
longer track the :TIMebase:RANGe value.
