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
