This command is used to set and query the switching mode between the single steps of the sweep function, and it can be set to TIMe or TRIG mode. <mode> TIME|TRIG|TIME_LOOP|TRIG_LOOP TIME_LOOP: Time loop sweep Copyright © ITECH Electronic Co., Ltd.

Page 128: Sweep:waveform
Query syntax: SWEep:WAVeform? Example SWEep:WAVeform "Sine" SWEep:WAVeform:PARameter <NRf+> This command is used to set and query the waveform parameters (for Example, the percentage of clipping wave. For waveform types without parameters, this parameter is invalid). Copyright © ITECH Electronic Co., Ltd.
