For example, :DISPlay:GRADing:TIME 1 /*Set the afterglow time to 1s*/ :DISPlay:GRADing:TIME? /*The query returns 1*/ :DISPlay:WBRightness For example, :DISPlay:WBRightness 50 /*Set the waveform brightness to 50%*/ :DISPlay:WBRightness? /*The query returns 50*/ :DISPlay:GRID For example, :DISPlay:GRID NONE /*Close background grid and coordinates*/ :DISPlay:GRID? /*The query returns NONE*/ :DISPlay:GBRightness 31 / 136 Function description Set or query the persistence time. The default unit is s. Parameter Name Type Range Default Discrete {MIN||1|5|10|30|INFinite} MIN Description ▷MIN: Set the afterglow time to the minimum value to observe the waveform that changes at a high refresh rate.
▷Specified value: Set the afterglow time to one of the above specified values, you can observe the burr with slow change or low probability of occurrence. ▷INFinite: When infinite persistence is selected, when the oscilloscope displays a new waveform, the previously acquired waveform will not be cleared. Measures noise and jitter to capture infrequent events. Return format The query returns MIN, 1, 5, 30, or INF. Command format :DISPlay:WBRightness :DISPlay:WBRightness? Function description Set or query the brightness of the waveform display on the screen. Parameter Name Type Range Default Integer 0 to 10 60 Return format The query returns an integer between 0 and 100.
Command format :DISPlay:GRID :DISPlay:GRID? Function description Sets or queries the type of grid displayed on the screen. Parameter Name Type Range Default Discrete {FULL|HALF|NONE} FULL Description FULL: Turn on the background grid and coordinates. HALF: Turn off the background grid and turn on the coordinates only. NONE: Turn off the background grid and coordinates. Return format The query returns FULL, HALF, or NONE. Command format :DISPlay:GBRightness :DISPlay:GBRightness? Function description Sets or queries the brightness of the screen grid.
