SECTION I

INTRODUCTION TO CIRCUIT DIAGRAMS

1.1 INTRODUCTION.

All circuit diagrams are in the foldout section of this TO. Figure 1 shows the integrated circuit pin locations that may be used in the glide slope station

1.2 SPECIAL GRAPHIC SYMBOLS.

Two nonstandard symbols are used on the glide slope station schematic diagrams.

1.3 TEST POINT IDENTIFICATION SYMBOLS.

1.3.1 Major Test Points. Identified by star encircled Arabic numerals. Used in checking the overall functions of assemblies or groups of components.

1.3.2 Secondary Test Points. Identified by encircled capital letters. Used in isolating fault to stages within assemblies or subassemblies.

1.3.3 Minor Test Points. Identified by a capital letter and Arabic numeral, both within a single circle. Used to isolate faults to components within a stage.
