Description of command 
If used as a setting command with the parameter ON this command sets all parameters of the subsystem (includ-

Description of command 
This command enables and configures up to 20 test tones. The minimum frequency spacing between two tones 
is 1 Hz. The sum of all test tones must not exceed the maximum AF generator level quoted in the data sheet.   
The following default test tones are provided: 
Tone <nr>  Frequency/[Hz]  Level/[V]  Enable   Tone <nr>  Frequency/[Hz]  Level/[V]  Enable

Note:  If the level of all test tones is derived from a total level (TLEVel setting in the 
CONFigure:MULTitone:AF1Channel:TDEFinition:MODE command), the individual level 
settings are ignored. The <Frequency> and <Enable> parameter settings are still effec-
tive.
