Access Procedures

Figure 6-3 shows the location of all major modules in the 5725A. View A is a top view,
and view B is a bottom view. Both views show the covers removed. The 5725A is
constructed so that two modules are completely accessible from the top, and two
modules are completely accessible from the bottom. Each of these four modules can be
lifted out of the chassis and locked in a service position by pivoting the assembly and
inserting two machined pegs into two machined holes in the chassis towards the center
of the instrument. (Figure 6-4 shows the High Voltage Amplifier assembly (A3) in the
Service position.) Once in the service position, a module can be removed completely by
disconnecting all cables attached to it.
