Sometimes the intensity stays tha same even if you try to adjust it. Probably someone has noticed it here. This issue appears at certain memory length settings, I think.
Hi Hydrawerk
I did some testing and noted that in the Video there was recording frames with the Persistence not set to Min.
when in Min persistence , and Frames are recorded and the Rigol will Play back the frames at a Fix normal visible intensity (about same as Infinite persistence brightness)
But when the persistence is not set to Min. the Frames are recorded at that intensity setting and you cannot adjust the playback intensity.
when the intensity is set low during record, you can Barely see the waveform
and
when the intensity is set High during record, you can Clearly see the waveform
What does persistence mean if recording frames? ( could be segmented frames)
Shown below are 4 Displays: 7% intensity, 50% intensity, 100% intensity, 0% intensity but Min. Persistence
I hope that helps show what happens
