Audio Precision ATS-1 Access - Operational Overview; Front Panel Controls and Connectors; FUNCTION Keys

Operational Overview
Front Panel Controls and Connectors
The ATS-1 Access front panel controls are grouped as shown in Figure
3-1. Each group is summarized in the following subsections.
FUNCTION Keys
The FUNCTION keys control the internal configuration of the
instrument. Each FUNCTION key corresponds to a particular
measurement function, such as Amplitude, THD+N, etc. A few of the
FUNCTION keys will invoke a second measurement function with a
second press of the key.
The FUNCTION keys and measurement functions are discussed in
detail in the section on controlling the Analyzer. See page 3-15.
