I need a feauture for a DSO, but dont know which DSO brands are capable of doing it. My Fluke 199C seems not to have this feuture.
I want to save the first 100ms of the power supply startup sequence to DSO memory.
I want to set a triger event ex: If the input goes over 100mV, the DSO will start to save the whole sequence until the memory is full. And very important if the memory is full, it will not roll to the beginning of the memory and rewrite the memory. It will just stop after the memory is full. It should be possible to zoom and look at this long sequence.
DSO have 1Mpoint memory.
Time division is 10ns.
My event starting trigger level is set as 100mV. It should mean if the input signal rises above 100mV, DSO will start to save with a sampling rate of 10ns until the memory of 1Mpoints is full. This means with a sampling interval of 10ns , 1Mpoints will be full after 10ms.
Once the starting event trigger is satisfied, the DSO should go ahead with the saving sequence independent of the trigger level.
Can any DSO do that?. If yes which one?
(I am trying to save the startup of a power supply as detiled as possible). Each point of the output with a resolution of 10ns after the input raises above 100mV.
