peak-to-peak is described as cumulative for 34465A but is it really?

Question asked by cl2 on Jul 20, 2019

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.

For example:

  data2:clear;:INIT;:fetch?;:data2?

and

  :INIT;:fetch?;:data2?

Behave the same way

 

So is the Compatibility document wrong or is there something I don't understand?
