Access to Internal Assemblies
Servicing the 8564EC or the 8565EC requires the removal of the
spectrum analyzer cover assembly and the folding down of six board
assemblies. Four of these assemblies lay flat along the top of the
spectrum analyzer and two lay flat along the bottom of the spectrum
analyzer. All six assemblies are attached to the spectrum analyzer right
side frame using hinges and fold out of the spectrum analyzer allowing
access to all major assemblies. See Figure 4-1 on page 179.
