With List operation applied to the alternating power supply, alternating waveform sequences 
in various ranges may be output. The surge/trapped wave may be added as required to 
simulate fluctuation of network voltage so as to evaluate the test result of the instrument 
under such situation. 
Various alternating sequences with output varied may be formed by listing the voltage, 
frequency, slope, surge/trapped wave each step.
