Hi,
A while ago I managed to acquire a? HP 85047A, unfortunately it has had an accident
sometime in it's life and Port1 is loose and slightly bent. I have measured the directivity
of the port and it seems to be in the right ballpark as far as performance is concerned.
However the whole sensor moves.
Opening up? the unit I see that whereas port2 is direct metal to metal contact where
the mounting screws are located, port1 has plastic washers between the two surfaces.
No matter what I try I cannot stop it moving. Anyone have any ideas?
Next week I should get an HP8753E opt 011 unit and I will then be able to see if the
Port1 sensor needs replacing or not.?
