1.1 Waveform Generator
• Produces an electrical voltage that varies with time.
• Periodic Signals: signal whose pattern is repetitive. For instance a sinusoid waveform.
PM 5139 - 20 MHz Frequency from 0.1 mHz to 20
MHz (20 Vpp). 24 Arbitrary waveform-
memoriesSee data sheet for details

1.2 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

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).

SIMULATORS3.1 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 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 Tutorial (from ECE343)

4. 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.

2.2 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.
