Return Format
The query returns the center frequency of the dual-tone signal in scientific notation, with 7 effective digits.
For example, 5.000000E+02 (the center frequency is 500 Hz).
Example
:SOUR1:FUNC:DUALT:CENTERF 500/*Sets the center frequency of the dual-tone signal of CH1 to 500 Hz.*/
:SOUR1:FUNC:DUALT:CENTERF? /*Queries the center frequency of the dual-tone signal of CH1 and the
query returns 5.000000E+02.*/

Syntax
[:SOURce[<n>]]:FUNCtion:DUALTone:FREQ1 {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]]:FUNCtion:DUALTone:FREQ1?
Description

Remarks
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns the frequency 1 in scientific notation, with 7 effective digits. For example, 5.000000E+02
(the frequency 1 is 500 Hz).
Example
:SOUR1:FUNC:DUALT:FREQ1 500 /*Sets the frequency 1 of the dual-tone signal of CH1 to 500 Hz.*/
:SOUR1:FUNC:DUALT:FREQ1? /*Queries the frequency 1 of the dual-tone signal of CH1 and the
query returns 5.000000E+02.*/
