When measuring rise time I have noticed that the rise time values seem to be somewhat proportional to the time/div setting. As the time/div setting gets smaller the rise time also follows suit.
When measuring rise time what is the best rule of thumb for the time/div value? It looks as for the most part that the rise time stays relatively unchanged until the max time/div setting is applied. I'm just looking for the best way to measure and report an accurate value. I have attached a few screen caps to supplement this narrative for clarification.
Any assistance is as always appreciated.
