:FUNCtion<m> Commands
:FUNCtion<m>[:FFT]:CENTer
Command Syntax
:FUNCtion<m>[:FFT]:CENTer <frequency>
<m> ::= 1-4 in NR1 format
<frequency> ::= the current center frequency in NR3 format.
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.
After a *RST (Reset) or :AUToscale command, the values returned by the
N O T E
: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.
