Theory of Operation
Overview
This chapter describes the internal operation of the M3500B/M5500B. This
description is at the functional-block level.
The information is presented in two ways:
PCA Descriptions
For each Printed Circuit Assembly (PCA), a
description of the major functions performed on that PCA.
System Functional Descriptions
For each major system function, a description of how the signal
is routed through the various PCAs.
In these descriptions, reference will be made to PCAs or features which are
optional and may not be present in the unit you have. In that case, simply
ignore those sections. The remaining PCA and Functional descriptions will
still apply.
