Let's say I record 1 ms of signal while set to a horizontal scale of 100 us. I can pan through the entire recorded signal, but if I try to zoom out horizontally to say 200 us, all the scope does is to make the horizontal trace half it's width. It doesn't actually display the additional data to the left and to the right of the original trace which has been captured. I can pan through this data still, but I cannot use the full horizontal real-estate to view it at horizontal scales longer than the scale used during capture.
Is what I am describing a bug, a limitation of the hardware or some sort of misconfiguration on my part?
