4.3 Other Waveforms and Functions
• Observe square and triangular waveforms from the function generator by pushing the
appropriate buttons. The frequency is not critical, but around 1 kHz works well.
4.4 Measuring Waveform Parameters
In this section you will be looking at AC waveforms again. A useful function of a scope is
to measure the peak to peak voltage and period of a voltage waveform. Display a 1 kHz
triangular wave on the scope. Adjust the other controls so that vertically the trace takes
up most of the screen and horizontally there is about one cycle of the input waveform on
the screen. Use the calibration of the VOLTS/DIV control to adjust how many volts per
box. On the left bottom corner of the screen will show the voltage division of horizontal grid
lines. Next, determine the peak to peak voltage of the triangular wave. Use the calibration
of the TIME/DIV control and the vertical grid lines on the screen to determine the period
of the wave. The display of the current time scale will be located in the middle bottom of
the screen. For both of these measurements judicious use of both the horizontal and vertical
position controls will enable you to utilize the finer markings on some of the grid lines of the
screen. The amplitude of the output of the function generator is not calibrated. You are
using the scope to measure this amplitude. The frequency output of the function generator is
calibrated and you should compare the function generator stated frequency with your period
measurement.
• Set the function generator to have a triangle wave output at 1Khz.
• On the function generator turn the amplitude knob fully clockwise.
• Use the oscilloscope to determine the peak and peak-to-peak voltages of the triangle
wave.
• Repeat for the sine and the square waveforms at 1 khz.
• On the function generator turn the the amplitude knob to the middle and determine
the peak and peak-to-peak voltages of all three waveforms at 1khz.
5 Using The DataStudio Oscilloscope
One of the displays available with DataStudio is the oscilloscope. This is not actually an
oscilloscope but software that closely mimics an oscilloscope.
1. The input for each trace is selected by an input menu button.
2. This scope is a storage scope. When you stop monitoring data the last trace is stored
for further use.
3. There is a smart cursor which is used in a similar way as in the graph display. It is
located on the top left of the DataStudio scope.
In comparison to the DataStudio oscilloscope, the BK scope is a much faster scope. The
highest frequency you can examine with the BK scope is 25 MHz. With the DataStudio
scope the highest frequency is 10 kHz. The other main difference between using the BK and
