1 INTRODUCTION

The PB-503 Analog/Digital Electronic Workstation is a versatile, time-saving tool
for circuit designers, engineering technicians, students, and hobbyists. A large
breadboard area and a wide choice of built-in circuit accessories allow rapid and
accurate construction of virtually any type of analog or digital circuit.

Circuit power is provided by three power supplies, two variable and one xed. The

circuit breadboard area includes over 2500 contact points. A multiple-waveform
function generator supplies sine, triangle, and square wave output for analog circuits.
A built-in speaker may be used for analog output.

Outputs also include a TTL-level square wave generator, two debounced pushbutton
switches, and a bank of eight logic switches. Eight logic indicators may be used
to display high and low logic levels. Two built-in potentiometers and two SPDT

switches are provided for circuit control and adjustment. Connections to external test

equipment or signal sources may be made using the two BNC connectors on the PB-

503.

The PB-503 eliminates the clutter and confusion that often results when constructing
sophisticated circuits. Alligator clips and similar connectors are seldom needed.
Sockets on the PB-503 allow insertion of components or wires of up to 20 gauge.

A detailed panel layout and description of the PB-503 is given in the section
“Description of Individual Features”.

2 Features & Applications

The PB-503 Analog & Digital Design Workstation is a robust electronics trainer
suitable for all levels of electronics instruction and design. Utilizing the PB-503,
students will learn valuable hands-on breadboarding techniques and build a solid

foundation in circuit experimentation, construction and analysis. Experienced
designers will nd the PB-503 an invaluable instrument, providing a reliable platform

for the most advanced and demanding design applications. The PB-503 can be used
to construct basic series and parallel circuits to the most complicated multi-stage
microcomputer circuits, incorporating the latest in industrial technology. Use the PB-

503 to construct a wide variety of experiments, including but not limited to.
