Global Specialties PB-503 Deluxe Analog and Digital Design Workstation, 0 to +/-10V, 16" Width x 6-1/2" Height x 11-1/2" Depth
The PB-503 Analog and Digital Design Workstation is a portable 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 find 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. Function Generator with continuously variable sine, square and triangle waveforms and TTL pulses. Triple output power supply offers fixed 5 VDC supply plus two variable outputs: +/-1.3 to +/-15VDC. Two Digital Pulsers. Audio experimentation speaker. Removable breadboard plate with additional plates available. Multiple features in one complete test instrument saves hundreds of dollars necessary for individual units. 3-wire AC line input (117V, 60 Hz typical) with power-on indicator. Both Models are available in 220-240VAC at 50Hz. 8 LED's, active high, 1.4 volt (nominal) threshold, inputs protected to +/-20 volts.
