PERCent <val><unit>
[:SOURce]:FM[1]|2:INTernal[1]:FREQuency:ALTernate:AMPLitude:PERCent?
This command sets the amplitude of the second tone for a dual-sine waveform as a
percentage of the total amplitude. For example, if the second tone makes up 30% of the
total amplitude, then the first tone is 70% of the total amplitude.
