1.1 Waveform Generator
• Produces an electrical voltage
that varies with time.
• Periodic Signals: signal whose
pattern is repetitive. For
instance a sinusoid waveform.
See data sheet for details

PM 5139 - 20 MHz
Frequency from 0.1 mHz to 20
MHz (20 Vpp).
24 Arbitrary waveformmemories

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.

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).

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 .
• 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).

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.
