## Description

Sets the persistence time when variable persistence is selected with the `:DISPlay:PERSistence:WAVeform` command. Newly acquired sample points are displayed at full intensity (brightest) while the intensity of previously acquired sample points fade to black during the defined persistence time. You can use this mode to view infrequent events and rapidly changing waveforms. You can set the time a waveform sample point is displayed from 100 ms to 40s, with one digit resolution. The default setting is 300 ms. If one of the following is changed, the displayed waveform is redrawn and any accumulated waveforms are cleared: the vertical or horizontal scaling, the vertical or horizontal position, the offset, the trigger source or level, a clear display is executed, or an Auto Scale is executed.
