Huntron Workstation 4 allows for any signature scan to be set as a “Reference” and used for comparison. This could be used to store References from several known good PCBs.
This can be extremely useful when dealing the differences in signatures from different IC manufacturers. Simply click the Set Reference button in the
Signatures/Troublesheet tab after scanning or select the Reference check box in the Tree/Component (or Net) Scans tab.
Although it is a legacy feature carried over from older Workstation versions,
Version 4 also has the ability to create a Merge signature set by clicking the Merge button in the Signatures/Troublesheet tab after scanning. The Merge function creates a listing
in the Component (or Net) Scans tab called Min/Max in addition to any scans set as a Reference.
To control which signatures are used for comparison, set the Compare Priority setting
by selecting Tree pane/Sequence tab and scroll right to the Compare Priority column.
