Hi
I have a requirement to measure a single phase AC output from an inverter, this is easily done on the Scope.
However a secondary requirement, which is to is to capture the inverter output AC sine wave falling to zero
when the inverter detects the power grid is unavailable.
To simulate a GRID failure I manually switch off the powwer from the GRID via a circuit breaker
I have tried the save option on the scope and set the number of frames to 70, 150 and 200 however this is not capturing the wave.
Can anyone give me advice on doing this ?
thanks
I have attached an example in the picture (this is a successfull capture . I am struggling to do the same)

Maybe you can use the scan mode. When the time base is less than or equal to 80ms, the device enters scan mode automatically.
