18 :FUNCtion<m> Commands
:FUNCtion<m>[:FFT]:CENTer
(see page 1276)
Command Syntax
:FUNCtion<m>[:FFT]:CENTer <frequency>
<m> ::= 1 to (# math functions) in NR1 format
<frequency> ::= the current center frequency in NR3 format. The range
of legal values is from 0 Hz to 25 GHz.
The :FUNCtion<m>[:FFT]:CENTer command sets the center frequency when FFT
(Fast Fourier Transform) is selected.
Query Syntax
:FUNCtion<m>[:FFT]:CENTer?
The :FUNCtion<m>[: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
:FUNCtion<m>[:FFT]:CENTer? and :FUNCtion<m>:SPAN? queries depend on the current
:TIMebase:RANGe value. Once you change either the :FUNCtion<m>[:FFT]:CENTer or
:FUNCtion<m>:SPAN value, they no longer track the :TIMebase:RANGe value.
