Global Specialties Model PB-503 is an Analog
& Digital Design Workstation. The PB-503’s
newly updated, robust design makes it a
trainer suitable for all level s of electro n ics
instruction and design.
The PB-503’s breadboarding area is
comprised of Global’s “Premium” solderless
breadboards and is backed by an industry
leading 3-year warranty.
The PB-503 can be used to construct basic
series and parallel circuits up to the most
complicated multi-stage microcomputer
circuits, incorporating the latest in industrial
technology.
The PB-503 allows students to learn valuable
hands-on lab experience by employing
necessary breadboarding techniques, which
provide a solid foundation in circuit
experimentation, analyzing and
troubleshooting.
Experienced designers will also find the
PB-503 an invaluabl e, capable and reliable
instrument, suit able for the most advanc ed
and demanding design applications.
Global Specialties trainers provide the most
complete platform required to enable
engineers and technicians to train for careers
in the rapidly growing field of electronics
technology.
Use the PB-503 to
construct a wide variety
of experiments, including
but not limited to:
Opto-Device Circuits
