In automatic measurements i realize that the values ??of active cycle are changed by the non active in the measurements, this occurs when the active +duty cycle is above 10%. The values ??remain right but point to the wrong cycles.
Using the generator itself for pwm signals with 70% duty cycle, the oscisloscope measures 30% in the +duty parameter.
In the manual, item 2.11.3 Measurement makes, all measurements, options 13 and 14 says the measurement of the period.
I am using the latest firmware revision dso4202c_20180305.0.


I am attaching an example of a square signal with active cycle at 70%. In the oscisloscope should appear 70% in + duty and 30% in -duty.

Hello, thank you for the update, it works, one suggestion is to also fix the -Pwidth is always zero. This helps a lot and increases production. I use these parameters a lot on the bench, classroom and labors.

Hello, is there any forecast for this review?  I am hoping to have these automatic measurements, would greatly reduce my time.

Hi amy, I hope you do not abandon this review, would not ask if it were not so important, I capture a lot of these screens to attach in my documentation.
