Rise Time

Post by marth »

I have a generator with a rise time of 24ns. Measurements in Picoscope do not look correct - 17.5 ns. Measurements on another oscilloscope are more accurate - 25,5 ns. I am attaching screenshots.

Hi Marth,

PicoScope 7 defaults to measuring Rise and Fall Times as 80/20. If you want 90/10, which is what the Rigol is using, then you need to select 90/10 in the Rise Time measurement.

Regards,

Hi Gerry,

Thank you for the clarification. Indeed, there is a setting for this ratio. It's comfortable.
