Syntax
[:SOURce[<n>]]:FUNCtion:DUALTone:CENTERFreq {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]]:FUNCtion:DUALTone:CENTERFreq?
Description
Sets the center frequency of the dual-tone signal of the specified channel.
Queries the center frequency of the dual-tone signal of the specified channel.

Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 The center frequency, frequency 1 and frequency 2 satisfy the following relations.

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.*/
