Global Specialt i es Model PB-505 is an
Advanced Analog & Digital Design
Workstation. The PB-505’s robust design
makes it a trainer suitable for all levels of
electronics instructio n and design.
The PB-505’s breadboarding area is
comprised of Global’s “Premium” solderless
breadboards and is backed by an industry
leading 3-year warranty.
The PB-505 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-505 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.
