:CURSor:TRACk:AY? For example, :CURSor:TRACk:AY? /*The query returns 284*/ :DISPlay Command Subsystem :DISPlay:CLEar For example, :DISPlay:CLEar /*Clear all waveforms on the screen*/ :DISPlay:TYPE For example, :DISPlay:TYPE DOTS /*Selection point display method*/ :DISPlay:TYPE? /*The query returns DOTS*/ :DISPlay:GRADing:TIME 30 / 136 Command format :CURSor:TRACk:AY? Function description Query the vertical position of cursor A during cursor tracking measurement. Description ▷The horizontal and vertical positions of the cursor are defined by the pixel coordinates of the screen. The pixel coordinates of the screen range from (0,0) to (770,400).
Among them, (0,0) is the upper left corner of the screen, and (770,400) is the lower right corner of the screen. The pixel range in the horizontal direction is 0 to 770, and the pixel range in the vertical direction is 0 to 400. ▷When cursor A is outside the vertical range of the screen display, the query fixedly returns 4294967295. Return format The query returns an integer. Command format :DISPlay:CLEar Function description Clear all waveforms on the screen. Description If the oscilloscope is in the RUN state, it will continue to display new waveforms after clearing. Command format :DISPlay:TYPE :DISPlay:TYPE? Function description Sets or queries how waveforms are displayed on the screen.
Parameter Name Type Range Default Discrete {VECTors|DOTS} VECTors Description ▷ VECTors: Displayed by connecting lines between sampling points. This mode provides the most realistic waveform in most cases. Easily view the steep edges of a waveform, such as a square wave. ▷ DOTS: Display sampling points directly. You can see each sampling point visually and use the cursor to measure the X and Y values of that point. Return format The query returns VECT or DOTS.
