[:SOURce[<n>]]:FREQuency[:FIXed]
Syntax [:SOURce[<n>]]:FREQuency[:FIXed] <frequency>
[:SOURce[<n>]]:FREQuency[:FIXed]?
Description If modulation is not enabled for the specified function/arbitrary waveform generator
channel, this command is used to set or query the output frequency of the specified
function/arbitrary waveform generator channel. If modulation is enabled for the
specified function/arbitrary waveform generator channel, this command is used to set
or query the carrier frequency of the specified function/arbitrary waveform generator
channel. By default, the unit is Hz.

Return
Format
The query returns the frequency value in scientific notation. For example
2.0000000E+5.
Example :FREQuency 1000 /*Sets the output frequency of GI to 1 kHz.*/
:FREQuency? /*The query returns 1.000000E+3.*/
[:SOURce[<n>]]:PHASe[:ADJust]
Syntax [:SOURce[<n>]]:PHASe[:ADJust] <phase>
[:SOURce[<n>]]:PHASe[:ADJust]?
Description Sets or queries the start phase of the signal of the specified function/arbitrary
waveform generator channel. By default, the unit is °.

Remarks When you perform the "align phase" operation, the instrument will re-configure the
two channels to output according to the preset frequency and phase.
For two signals whose frequencies are the same or in multiple relationship, this
operation can align their phases.
