[:SOURce[<n>]]:FUNCtion:DUALTone:FREQ2
Syntax
[:SOURce[<n>]]:FUNCtion:DUALTone:FREQ2 {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]]:FUNCtion:DUALTone:FREQ2?
Description
Sets Frequency 2 of the dual-tone signal of the specified channel.
Queries Frequency 2 of the dual-tone signal of the specified channel.

Real
1 μHz to 20 MHz
1 kHz
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 2 in scientific notation, with 7 effective digits. For example, 5.000000E+02
(the frequency 2 is 500 Hz).
Example
:SOUR1:FUNC:DUALT:FREQ2 500 /*Sets the frequency 2 of the dual-tone signal of CH1 to 500 Hz.*/
:SOUR1:FUNC:DUALT:FREQ2? /*Queries the frequency 2 of the dual-tone signal of CH1 and the
query returns 5.000000E+02.*/
[:SOURce[<n>]]:FUNCtion:DUALTone:OFFSETFreq
Syntax
[:SOURce[<n>]]:FUNCtion:DUALTone:OFFSETFreq {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]]:FUNCtion:DUALTone:OFFSETFreq?
Description
Sets the offset frequency of the dual-tone signal of the specified channel.
Queries the offset frequency of the dual-tone signal of the specified channel.
