Oscilloscopes Flashcards
What is this test equipment called and what can it measure?
The oscilloscope can directly measure:
• Amplitude (voltage)
• Period (time)
• Waveshape
The waveform (waveshape) displayed on the oscilloscope is called what?
Trace
Dual trace oscilloscopes have four major functional sections. Name the sections.
The display has a screen marked off with lines called _____. It is used on the display to measure the ____ and _____ (voltage) of waveforms.
The display has a screen marked off with lines called divisions. The divisions on the display are used to measure the time and amplitude (voltage) of waveforms
Each horizontal division represents a time value.
Each vertical division represents a voltage value.
Oscilloscopes can be used to derive frequency by measuring _______.
time per cycle
The phase angle of a displayed waveform is a derived quantity measured in _______
degrees
What is the TRACE on an oscilloscope?
Shape of the waveform
What value of AC voltage does an oscilloscope measure?
Peak-to-peak
Most oscilloscopes directly measure waveform shape, ___ and _____
voltage and time
Which functional area controls the amplitude?
Vertical
What is the difference between a oscilloscope and a function generator?
An oscilloscope is used to measure signals
A function generator produces AC signals.
Which modification of the output signal changes the amount of AC voltage?
Amplitude
The output signal of a function generator is FM modulated by changing the _______.
frequency of the output signal
What is the display used for on a function generator?
To indicate the frequency of the output signal.
Which modification of the output signal changes the number of cycles per second?
Frequency
Which modification of the output signal changes the shape?
Symmetry
What do the RANGE buttons select?
Frequency
Which combination of buttons and controls set the amount of DC voltage that the AC signal rides on?
DC Offset
Which control adjusts the amplitude of the output signal?
Output Level
Which control is used with the Range buttons to select the frequency where the sweep operation begins?
Start
