LAB Final – Study Guide
Student Name: ___________________________________________________
Overview
To complete the hands-on lab final exam,
you must complete the following steps:
1. Sign up for a one-hour time slot to take
the exam on the last lab session.
2. Bring a USB Flash drive to save
oscilloscope display images.
3. Arrive at your scheduled time for the
exam. Do not come early, as this would
be a distraction for the other students.
4. Complete the activities as described on
the exam within 50 minutes. An
overview of the activities is given below.
5. At the conclusion of your exam, turn in
your Lab Activity Binder for grading,
and leave the room to avoid distracting
the other students.

You may use your notes and Lab
Activity Binder for reference during the
exam, but keep in mind that you may not
be able to complete the exam if you
spend too much time looking up
information.
If you arrive late for the exam you must
still finish at the scheduled time.
If you suspect that a circuit is
malfunctioning, you may ask the
instructor to check the circuit. The
instructor will not resolve problems
resulting from errors in measurement.
There are no “gotcha” or trick questions
on the exam. All measurements and
calculations are standard technicianlevel procedures.
Read the instructions for each step
carefully. Not following instructions is
not the same thing as a “trick question.”

All measurements must be accurate
within 5% for full credit. Where
appropriate, correct units, prefixes, and
polarity must be used.


Measure resistance of two resistors with
the digital multimeter (DMM).
Measure two DC voltages with the
DMM.
Measure the peak-to-peak input and
output voltages, period, gain, and phase
of an amplifier circuit with the NIELVIS virtual oscilloscope tool. Set the
vertical, horizontal, and triggering
controls to produce a display that
facilitates the above measurements.
Compensate a 10x scope probe
connected to Channel 2 of the
MSO2014. Remove any other input
displays from the screen. Set the vertical,
horizontal, and triggering controls to
produce a display that facilitates the
above measurement. Save the screen
display on your flash drive.
Set the Fluke function generator to
output a specified waveform. Measure
the period, phase, and peak-to-peak
amplitude of two sine waves with the
Tek MSO2014. Calculate the RMS
voltage.
Display digital data on digital inputs D0D7, and analog data on Channel 1 on the
Tek MSO2014. Measure the analog
voltage at a time determined by the
digital data. Set the vertical, horizontal,
and triggering controls to produce a
display that facilitates the above
measurements. Save the screen display
on your flash drive.
