HP 16510B, 16500A manual Creating a Compare Image

Creating a Compare Image

The controls that roll the list in all three menus, the normal State Listing, the Compare Listing, and the Difference Listing are synchronized. This means that when you change the current row position in the Difference Listing, the logic analyzer automatically updates the current row in the acquired State Listing, Compare Listing and vice-versa. This allows you to view corresponding areas of the two lists, to cross check the alignment, and analyze the bits that do not match.

Since time tags are not required to perform the compare, they do not appear in either the compare image or difference displays. However, correlation is possible since the displays are locked together.

An initial compare image can be generated by copying acquired data into the compare image buffer. When you select the "Copy Trace to Compare" field in the Compare Listing menu a pop-up appears with the options "Cancel" and "Continue". If the "Continue" is selected, the contents of the acquisition data structure for the current machine are copied to the compare image buffer. The previous compare image is lost if it has not been saved to a disk. If you select "Cancel" the current compare image remains unchanged.
