Test Equipment Flashcards
How is a frequency counter used?
To measure the time between events, or the frequency, which is the reciprocal of the time.
What is a frequency standard?
A device used to produce a highly accurate reference frequency.
What equipment may be useful to track down EMI aboard a ship or aircraft?
Portable AM receiver.
On an analog wattmeter, what part of the scale is most accurate and how much does that accuracy extend to the rest of the reading scale?
The accuracy is only at full scale, and that absolute number reading is carried through to the rest of the range. The upper 1/3 of the meter is the only truly calibrated part.
Which of the following frequency standards is used as a time base standard by field technicians?
Rubidium Standard.
Which of the following contains a multirange AF voltmeter calibrated in dB and a sharp, internal 1000 Hz bandstop filter, both used in conjunction with each other to perform quieting tests?
SINAD meter
