The peak to peak description in the "Compatibility and Differences: 34465A and 34410A..." says it is cumulative in the 34465A model but it does not seem to behave that way. It suggests (and the operating guide uses it in the sample code) to use clear (DATA2:CLEAR) before INIT.
However I get the same result whether or not I use the clear.
If it was cumulative I would expect the peak values to only increase from one call to the next. However the can both increase or decrease even without the clear.
Behave the same way
So is the Compatibility document wrong or is there something I don't understand?
