HP8566b Bandwidth Adjustment

[tkamiya]

As part of alignment procedure, display section of HP8566B spectrum analyzer has to be adjusted.  Filter Bandwidth adjustment is done as part of the display section.  I recall seeing *somewhere* chain of filter has to be bypassed all except for one that is tweaked, so that they are isolated.  I spent few days looking for a documentation or a web page explaining how this is done, but alas I cannot find one.  Can anyone please point me to the right direction?

Did you ever find a solution for this question? I have a complete tests and adjustment manual set. I remember reading about this procedure, I believe construction of bypass filters is required, of which parts and schematics for building them is included.
