what do boxes in schematic want to tell me?

 

Hi,
?
I am trying to fix an HP83732A. While studying the CLIP I was wondering what the information inside the rectangles marked in red mean.
I couldn't find any references in the manual. Can anybody enlighten me? Could this be stripline dimensions?

The size of the indicated (and in bold) trace.

Harold beat me to it but here I go, anyway.
The transmission line behavior of the copper traces is an active part of the circuit.? The numbers are length and width in inches.

That's what I suspected. I find it odd though, that such details are disclosed to the public.

I would strongly suspect that it may be circuitry that is part of the circuit brd. such as a filter or other circuit. Some times they may indicate an encapsulated, micro circuit assy., or shielded circuit on a brd.

This is what the board looks like.
So, it must be those 50 Ohms tracks and stubs.
