Preface
This AM700 Audio Measurement Set Service Manual is intended for use by
qualified service personnel as a tool for troubleshooting, repair, and under-
standing of the AM700. No servicing of circuit boards should be attempted
during the Warranty period of the instrument. Repair of the instrument when a
defective circuit board is determined to be the cause of a failure is by board
exchange. Both the CRT display and the flat-panel color display versions of the
AM700 are covered in this service manual.
Specifications
This section provides a brief description of the features of the AM700 Audio
Measurement Set, a list of the options and accessories available for use with the

These tables provide numerical values for measurement accuracies for those
characteristics that may be measured and functional descriptions for those
functions that require a definition of their operation.
Operating Information
An introduction to how the AM700 operates is provided in this section to assist a
service person in becoming familiar with the user interface and accessing the
many application menus. A description of the power requirements and main fuse
location is also found at the beginning of the section.
Theory of Operation
A quick overview of the functional blocks of the AM700 introduces the service
person to the basic architecture of the circuit boards in the Block Circuit
Description. That is followed by a more detailed description of the circuitry of
the AM700 with block diagrams and references to the schematic diagrams to
assist in obtaining a more indepth understanding of the functional blocks of the
AM700. The circuit descriptions are mainly to assist the service person in
narrowing the number of choices of circuit boards that may require swapping to
effect repairs to a malfunctioning instrument.
