2 Command System RIGOL
:DISPlay:GRADing:TIME
Syntax
:DISPlay:GRADing:TIME
:DISPlay:GRADing:TIME
Description
Set the persistence time and the unit is s.
Query the current persistence time.
Parameter
Name Type Range Default
Discrete {MIN|0.05|0.1|0.2|0.5|1|2|5|10|20|INFinite} MIN
Explanation
MIN: set the persistence time to its minimum to view the waveform changing in high
refresh rate.
Specific Values: a certain value between 0.05 s and 20 s, enable to observe glitch
that changes relatively slowly or glitch with low occurrence probability.
INFinite: in this mode, the oscilloscope displays the newly acquired waveform
without clearing the waveform formerly acquired. Enable to measure noise and jitter
as well as capture incidental events.
Return Format
The query returns the persistence time set.
Example
:DISPlay:GRADing:TIME 0.1
The query returns 0.1.
