[SOURce[1|2]]:FREQuency[:CW|:FIXed]
This command sets or queries the frequency of output waveform for the specified
channel. This command is available when the Run Mode is set to other than Sweep.
The setting range of output frequency depends on the type of output waveform. If
you change the type of output waveform, it might change the output frequency
because changing waveform types impacts on the setting range of output
frequency.
