Remarks The alternate frequency is the second tone of a dual-sine or the stop
frequency of a swept-sine waveform.
Refer to “:PM[1]|2:INTernal[1]|2:FUNCtion:SHAPe” on page 275 for
the waveform selection.
:PM[1]|2:INTernal[1]:FREQuency:ALTernate:AMPLitude:PERCent

PERCent <val><unit>
[:SOURce]:PM[1]|2:INTernal[1]:FREQuency:ALTernate:AMPLitude:PERCent?
This command sets the amplitude of the second tone for the 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.
