Global Specialties PB-505
Shown

An exceptional combination of advanced functions, features plus exceptional performance, workmanship and flexibility of circuit design makes the new Global Specialties PB-505, a valuable cost effective product for design engineers, educational institutions and hobbyists.

This advanced design workstation feature life-time guarantee on all breadboarding sockets and 3 year warranty on all parts and workmanship.

The Global Specialties PB505 features a larger removable breadboard area (3360 uncommitted tie points) and optional additional breadboard socket plates (part number 325-1448)

The Global Specialties PB 505 also features eight high (red) and low (green) buffered logic LED indicators, eight individual selectable logic switches offering settings of plus, negative and uncommitted, a built in logic probe with pulse capture, a built in multi-function, multi-wave 100KHz, function generator with continuously variable sine, square and triangle wave forms and TTL pulse.

Besides the standard triple output power supply (2 variable and 1 fixed), two digital pulsers, audio experimentation speaker, SPDT switches, potentiometers and debounced pushbutton switches, This new advanced trainer also features a BCD to 7 segment decoder/display, special AC voltage output 12, 6 AC, center tapped at 6.3VAC, larger individual breadboard socket areas and is housed in a rugged metal enclosure.
