17 :FFT Commands
:FFT:CENTer
(see page 1276)
Command Syntax
:FFT:CENTer <frequency>
<frequency> ::= the current center frequency in NR3 format. The range
of legal values is from 0 Hz to 25 GHz.
The :FFT:CENTer command sets the center frequency when FFT (Fast Fourier
Transform) is selected.
Query Syntax
:FFT:CENTer?
The :FFT:CENTer? query returns the current center frequency in Hertz.
Return Format
<frequency><NL>
<frequency> ::= the current center frequency in NR3 format. The range
of legal values is from 0 Hz to 25 GHz.

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