:DISPlay:GRADing:TIME
Syntax
:DISPlay:GRADing:TIME <time>
:DISPlay:GRADing:TIME?
Description
Sets or queries the persistence time. The default unit is s.
Parameter
Name
Type
Range
Default
<time>
Discrete
{MIN|0.1|0.2|0.5|1|2|5|10|INFinite}
MIN
Remarks
 MIN: sets the persistence time to its minimum value to view how the waveform
changes at a high refresh rate.
 specified value (e.g. 0.1, 0.2, 0.5, 1, 2, 5, 10): sets the persistence time to any of
the above specific value to observe glitch that changes relatively slowly or glitch
with low occurrence probability.
 INFinite: In this mode, the oscilloscope displays the waveform newly acquired
without clearing the waveforms acquired formerly. It can be used to measure
noise and jitter and to capture incidental events.
Return
Format
The query returns MIN, 0.1, 0.2, 0.5, 1, 2, 5, 10, or INF.
Example
:DISPlay:GRADing:TIME 0.1 /*Sets the persistence time to 0.1 s.*/
:DISPlay:GRADing:TIME? /*The query returns 0.1.*/
:DISPlay:WBRightness
Syntax
:DISPlay:WBRightness <time>
:DISPlay:WBRightness?
Description
Sets or queries the brightness of the waveforms on the screen, expressed in
percentage.
Parameter
Name
Type
Range
Default
<time>
Integer
1 to 100
60
Return
Format
The query returns an integer ranging from 1 to 100.
Example
:DISPlay:WBRightness 50 /*Sets the waveform brightness to 50%.*/
:DISPlay:WBRightness? /*The query returns 50.*/
:DISPlay:GRID
Syntax
:DISPlay:GRID <grid>
:DISPlay:GRID?
Description
Sets or queries the display type of the screen grid.
Parameter
Name
Type
Range
Default
<grid>
Discrete
{FULL|HALF|NONE|IRE}
FULL
Remarks
FULL: turns on the background grid and coordinates.
HALF: turns the background grid off and turns the coordinate on.
NONE: turns the background grid and coordinate off.
IRE: the IRE command is only valid when the trigger type is Video trigger and the scale
