PROJECT NAME : BLCB1 v1 rev3 SCOPE : Upgrade BLCB1 v1 rev2 PCB to rev3 DATE : 10-2015 1 REQUIREMENTS & GENERAL SPECIFICATIONS 1.1 PCB Design must be made using Altium® versión 14. 1.2 The purpose of this job it is to upgrade the existing BLCB1 v1 rev2 board to BLCB1 v1 rev3 board, using circuit schematic file BLCB1 v1 rev3.SchDoc and BLCB1 v1 rev2.PcbDoc provided by GBX. 1.3 Circuit schematic files provided by GBX contains all the information about every component on the following fields: 2. VALUE, 3. MAN BRAND, 4. MAN P/N and 5. DATASHEET LINK. In a question, doubt or comment about any component during the design process the PCB designer must immediately contact GBX for clarifications. 2 JOBS DESCRIPTION 2.1 Implement the circuit schematic BLCB1 v1 rev3.SchDoc over the existing PCB file BLCB1 v1 rev2.PcbDoc to generate the PCB file PCB file BLCB1 v1 rev3.PcbDoc making as mínimum changes as possible. Files BLCB1 v1 rev3.SchDoc and BLCB1 v1 rev3.PcbDoc will be provided by GBX t...

Summary of requirements: 1. Experiment generally includes a signal / waveform generator and DSO (digital storage oscilloscope) used to detect interference in waveforms over a simulated "Homeplug" (and other) low-voltage (110V) powerline network. That is, on an active 110V AC circuit, the signal generator is at one end, the DSO at the other end. We then will introduce different types of interference (a later project) once the experiment design is created, any equipment purchased and any circuits (couplers see below) built and tested. 2. Choice of DSO and Waveform generator. Lowest cost that meets the following requirements, and your recommendations (i.e., dealing with impedance etc.) I. Continuously storing data to a PC. II. DSO ? 4 inputs (or 2 units each with 2 inputs) III. Must include software to convert data to a format read by Matlab and R. 3. Variations in experiment: I. We will vary the wavelength of the waveforms from 2 to 86 Mhz and if practical, as low a...
