How do you measure duty cycle on a signal that has an ofset. :?

The software handles this by looking at max/min and crossings of the half way point between the two.

Hi Martyn
Thank you for your reply I must apologise for not stating my question properly. I am trying to measure the duty cycle of a square wave with a high level of 4.06 volts and a low level of 1.89 volts and a cycle time of 330 micro seconds but picoscope struggles to give a measurement. :?

There does appear to be an issue with measuring the duty cycle when it is offset from zero, as in your case. As the development team are currently working on measurements I thought I would test against a pre release version which will appear as a Beta shortly and it does measure duty cycle.

Keep an eye on the forums for this beta release.
