OPTI 380B Intermediate Optics Laboratory
Lab 1: Basic Circuit
Construction and Electronic Instrumentation
Objective:
Lean how to use:
A breadboard to build electronic circuits
The Wavetek 85XT handheld digital multi-meter (DMM) to measure V, I, and Ω.
The Agilent HP34401 digital multi-meter (DMM) to measure V, I, and Ω.
The Tektronix TDS1002 Oscilloscope.
The B&K 4003 Function Generator.
The Agilent E3640A Programmable Power Supply.
Reading Assignments:
“Prototype Board Explanation”, “Instruments”
“HP34401 manual (‘select’ pages)”
“XYZs of Oscilloscopes” (reference material)
“AVG and RMS Values of Periodic Waveforms”
PreLab Questions:
[PL1] Explain the relationship between the average and RMS values for a time-varying signal.
[PL2] After reading XYZs of Oscilloscopes(pg. 18-21, 27-31 in particular), answer the following questions:
In an oscilloscope trace, what measured quantities are displayed on the vertical and horizontal axes?
How do I change the units per division being displayed for the horizontal and for the vertical axes?
What is the purpose of the trigger?
What is the difference between AC and DC coupling?
[PL3] What value of resistor is needed, in series with a 9V battery, to limit the current to 15mA?
[PL4] In order to produce a 1V RMS reading, what does the peak value of a sine wave have to be?
[PL5] What is the expected RMS value for a 1V peak square wave?
[PL6] What is the expected RMS value for a 1V peak triangle wave?
