Stops running the oscilloscope. This command functions the same as clicking or tapping the icon in the quick operation bar or pressing the corresponding front-panel key.
Performs a single trigger and sets the oscilloscope trigger mode to Single. It functions the same as :TRIGger:SWEep SINGle.
Generates a trigger signal forcefully. It is only applicable in the normal and single trigger modes.
Enables the waveform auto setting function. The oscilloscope automatically adjusts the vertical scale, horizontal time base, and trigger mode according to the input signal for optimal waveform display.
Sets or queries whether the peak-peak priority setting is enabled.
