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.
