Post any questions you may have about our current range of oscilloscopes
I'm doing rise time measurements using an external generator. Square wave is 2kHz, 10Vpp.
80/20% measurement tells me 400ns but 90/10% says 153us (!)
Adding cursors to the graph indicates 680ns for the 90/10%.
Why is the 90/10% measurement so far out?

We are currently looking at the Picoscope 6 measurements as there may be a few inaccuracies with these.

HI I have investigated this myself and there is a problem with the 10- 90% calculations for rise and fall time. The software engineers are aware of it and we will be looking at fixing this.
