18 :FUNCtion<m> Commands
:FUNCtion<m>:FFT:FREQuency:STOP
(see page 1276)
Command Syntax
:FUNCtion<m>:FFT:FREQuency:STOP <frequency>
<m> ::= 1 to (# math functions) in NR1 format
<frequency> ::= the stop frequency in NR3 format.
The :FUNCtion<m>:FFT:FREQuency:STOP command sets the stop frequency in the
FFT (Fast Fourier Transform) math function's displayed range.
The FFT (Fast Fourier Transform) math function's displayed range can also be set
with the :FUNCtion<m>[:FFT]:CENTer and :FUNCtion<m>[:FFT]:SPAN commands.
Query Syntax
:FUNCtion<m>:FFT:FREQuency:STOP?
The :FUNCtion<m>:FFT:FREQuency:STOP? query returns returns the current stop
frequency in Hertz.
Return Format
<frequency><NL>
<frequency> ::= the stop frequency in NR3 format.
