A test equipment item that has the ability to produce either square, triangular, or sawtooth waveforms is called:
The phase difference between sine waves of different frequencies is:
What is the rms voltage value of an ac signal whose peak oscilloscope display uses 3 major divisions above the zero setting? (V/cm = 5)
What is the waveform period difference between the 60 Hz electricity used in this country and the 50 Hz used in Europe?
If a voltmeter measures a sine wave as 500 mV, what would be its average value?
What is the period of a 16 MHz sine wave?
The distance that a signal's energy can travel in the time it takes for one cycle to occur is called the signal's:
What is the name of a device used to directly measure the frequency of a periodic wave?
What does the CRT oscilloscope display?
If a sine wave signal is 100 mV peak-to-peak, how many volts would be measured by a voltmeter?
What is the peak-to-peak current value when an ammeter measures a 20 mA value?
How long would it take to transmit an electromagnetic wave to a receiving antenna 1,000 miles away?
Test equipment selection enables the technician to both generate signals and:
Why is ac current transfer more effective than dc current transfer over long distances?
DC current flows in one direction, while ac current rises from zero to a maximum, then falls to zero in one direction, then rises to a maximum, then falls to zero in the opposite direction.
The letter in the Greek alphabet used to represent wavelength is __________.
One adjustable knob on the oscilloscope that allows the trace to be aligned with a reference graticule is called the:
One oscilloscope selector knob that allows the major and minor divisions of the graticule to be used to determine a signal amplitude value is called the:
If current varies periodically from zero to a maximum, back to zero, and then repeats, the signal is:
Which control should be moved to display more cycles of a signal on an oscilloscope?
