MEASure:CURRent:HARMonic:PHASe?    
FETCh:CURRent:HARMonic:PHASe?   
Phase Selectable 
These queries return the phase angle of the Nth harmonic of output current, referenced to the positive 
zero crossing of the fundamental component. 
The  parameter  is  the  desired  harmonic  number.  Queries  sent  with  a  value  of  0  return  the  dc 
component. A value of 1 returns the fundamental output frequency. Harmonic orders can be queried 
up to the fundamental measurement bandwidth of the measurement system: 
10.4 microseconds for single-phase mode and 31.2 microseconds for three-phase mode. 
Thus, the maximum harmonic that can be measured is dependent on the output frequency.  Any 
harmonics that represent frequencies greater than above frequencies are returned as 0.
