6/15/2002 ECE Waveform Generator Produces an electrical voltage that varies with time. Periodic Signals: signal whose pattern is repetitive. For instance a sinusoid waveform. PM MHz Frequency from 0.1 mHz to 20 MHz (20 Vpp). 24 Arbitrary waveform- memories See data sheet for details

6/15/2002 ECE Digital Oscilloscopes Oscilloscopes are typically used to measure the characteristics (such as amplitude, rise and fall times, etc) of a voltage signal with respect to time. Specifications: –1 GSample/sec simultaneously on 2 channels –500 MHz analog bandwidth –1 ns peak detect –Optional expansion modules for FFT, waveform storage, and remote control –Sweep speeds from 1 ns/div to 5 s/div HP 54616B HP 54616C Manual

6/15/2002 ECE 345 SCOPE PROBES Oscilloscope Probes An oscilloscope probe measures the electric signal at the source and transport them to the input channel of the scope. An IDEAL PROBE would execute this task without causing any perturbation on the circuit under test (or without LOADING it). Exercises

6/15/2002 ECE 345 SIMULATORS 3.1 ADS (Agilent Advance Design System) A powerful electronic design software system. It offers complete design integration to designers of products such as cellular and portable phones, pagers, wireless networks, radar and satellite communication systems. ADS TutorialADS Tutorial (from ECE 351) 3.2 Pspice/Orcad OrCAD is a useful development package that includes programs for making schematics of digital or analog circuits (Capture), simulating those circuits (PSPICE), and laying out printed circuit boards (Layout Plus). PSPICE TutorialPSPICE Tutorial (from ECE343)

6/15/2002 ECE GRAPHICS CONTROL SOFTWARE 4.1 HPVEE The VEE programming environment is a tool for integrating test and measurement equipment in a computer. It allows for control and display of any HPIB devices on the bench (oscilloscopes, multimeters, spectrum analyzers, etc.). If you need to capture and print something off a scope, this is the software to use. HP VEE Tutorial

6/15/2002 ECE Soldering Safety Always solder in a well ventilated area! Never eat, drink or smoke while soldering. Wash your hands thoroughly with soap and water before doing anything else! Never leave your soldering iron plugged in when not in use or unattended! Never override the grounding system on your soldering iron (or any other tool)! Legs and arms should be covered to avoid burns from splashed hot solder. How to solder recommendations
