I have this weird Infinite Persistence problem on my pcsgu250, and i remember it used to work fine.
When i have the Persistence button on (and Infinite Persistence set on), the screen gets periodically cleaned like every second and starts from the scratch, so i can’t really get a steady persistent display.
Yes, the screen is refreshed to show new waveform parameters on the screen.
I’m sorry that the persistence option is not working in this mode.
Thank you for the feedback.
