Lab: Oscilloscope and Signal Generator Use
Make sure before you apply an input signal to a circuit, all connections are
correct, and no shorted wires exist.
1. Exploring the Oscilloscope
Do not short the function generator signal and ground connections together.
Do not touch the circuit wiring while power is applied to it.
Locate the Digital Oscilloscope and obtain two scope probes.
Press the white POWER button to turn on the oscilloscope on the lower left of
the front panel. See 1 in Figure 1: Oscilloscope Controls.
Press the [Help] button. Familiarize yourself with how the controls are changed
using the dials, buttons, or softkeys. The [Help] button is in the lower right of the
manual controls area. See 2 in Figure 1: Oscilloscope Controls.
Press the Default Setup to return the oscilloscope to the default state (Always use
the default before you begin using the oscilloscope!) See 3 in Figure 1:
Oscilloscope Controls
Connect the two probes to their input connectors, marked as 1 or X and 2 or Y on
the Scope. See 4 in Figure 1: Oscilloscope Controls.
Clip the channel 1 (CH 1) probe to the Probe Comp test point at the lower right
below the display. The probe tip goes to the Probe Comp (5). See 5 in Figure 1:
Oscilloscope Controls.
Clip the probe's ground clip to the oscilloscope ground connection to the right of
the Probe Comp test point. The ground clip goes to the horizontal grounding
strip (6). See 6 in Figure 1: Oscilloscope Controls.
Press the Auto-Scale button to acquire the test waveform (i.e., a square wave).
See 7 in Figure 1: Oscilloscope Controls.
Change the vertical scale of the waveform using the CH 1 Volts/Division knob
that is just above the 1, illuminated channel activation button. See 8 in Figure 1:
Oscilloscope Controls. ECE 206

Lab: Oscilloscope and Signal Generator Use
Note the Vertical Scale Readout changing in the upper left of the screen and the
displayed waveform changing size as the knob is adjusted. See 1 in Figure 2:
Oscilloscope Screen.
Change the horizontal scale of the waveform using the Sec/Division knob, left
most, top most knob. See 9 in Figure 1: Oscilloscope Controls.
Note the Horizontal Scale Readout changing as the knob is adjusted. See 3 in
Figure 2: Oscilloscope Screen
Press the Auto-Scale button again to resize the waveform
Press the [Meas] button. { See 10 in Figure 1: Oscilloscope Controls.} The
Frequency and peak to peak voltage of channel 1 automatically appears in the
window to the right of the signal window on the display. { See 4 in Figure 2:
Oscilloscope Screen.} Additional measurements for selection can be found using
the lower soft keys under the Screen. The [TYPE] button.{ See 5 in Figure 2:
Oscilloscope Screen.} will produce measurements window on the display, it has a
scroll control knob on the right of the screen for selection {See 6 in Figure 2:
Oscilloscope Screen}
To remove a measurement from the Meas window, use the [Clear Meas], {See 7
in Figure 2: Oscilloscope Screen} Follow the other soft keys that appear.
Record the frequency and peak-to-peak voltage (Vpp) of the square wave in your
lab notebook
Unclip the CH 1 probe and ground clip from the oscilloscope test point and set
them aside
Clip the channel 2 (CH 2) probe and ground clip to the Probe Comp and ground
connections respectively
Repeat the frequency and amplitude measurements for the CH 2 waveform
Clear the screen measurements as before.
Unclip the CH 2 probe and ground clip from the oscilloscope, and set them aside
Always test both probes before taking measurements with them! The test signal
from the oscilloscope should appear square and symmetrical, with no rounding. ECE 206
