How does an oscilloscope measure time?
An oscilloscope does not measure time. It is used to plot signals which are displayed as a change of voltage against (or with reference to) a change in time. To do this, the scope has to have something inside it to generate a "time tick" or otherwise provide a time reference. We usually find that a crystal oscillator is doing that job.
What type of electrode is a cold cathode?
Cold cathode is a cathode, an electrode that emits electrons, which is not electrically heated by an element. Cold cathodes are used in gas discharge lamps such as neon lamps and discharge tubes.
Why is the cathode-ray tube in figure 4 connected to a vacuum pump?
A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.
Why is the positive electrode used up in electrolysis?
Thise electrode is the cathode.
Which oscilloscope control is used to move the trace up and down the screen vertically?
More than likely, it is the DC Offset.
How a Cathode Ray Oscilloscope is used to measure Alternating current?
An oscilloscope is, essentially, a voltmeter -it measures current by measuring the voltage drop caused by that current across a standard resistance.
What does the term oscilloscope mean?
The meaning of the word oscilloscope is a device used for viewing oscillations, electrical current or voltage or, with a display on the screen of a cathode-ray tube.
What tools are used to measure sound?
an oscilloscope is used to measure sound waves
What is needed to convert normal sound waves into a form that can be used inside as computer?
CRO; a cathode ray oscilloscope
What are oscilloscope probes use for?
Oscilloscope probes are used as part of an Oscilloscope. These are the pieces that connect to your circuit in which you would like to measure its sine waves.
What CRO stand for?
Cathode Ray Oscilloscope - referring to the display component itself (cathode ray tube, as used to be used on televisions and computer monitors). Most oscilloscopes now use l.c.d. monitors; or can be synthesised on a PC with suitable software.
An oscilloscope can be used to produce visible pictures of sound waves. If an oscilloscope is used to measure the distance between the crests of a sound wave what property of the wave will it be measu?
Wavelenght
What is the difference between cathode ray oscilloscope and digital storage oscilloscope?
CRO means cathode ray oscilloscope. The Cathode Ray tube is the display mechanism only. A CRO can be a digital or analog scope, with or without digital storage. A digital storage scope can use a CRO as the display mechanism, or it can use a LCD screen, or any other method. There was a type of Cathode Ray tube that used analog means to store the information on the screen, The storage takes place on the screen itself. They were pretty rare, and not seen at all today, as they didn't work very well. Perhaps that is what you are referring to?
When a signal of 10 mV at 75 MHz is to be measured then What instruments can be used?
When a signal of 10 mV at 75 MHz is to be measured then which of the following instrument can be used -
Using a cathode ray oscilloscope how do you measure the current in an electric circuit?
Cathode ray oscilloscope(CRO) is a device used to see the voltage across a particular element of your circuit and the wave form can also be seen on CRO. But you actually cannot measure the current using CRO as it is meant to give the voltage levels across any element in eletrically enegized circuit. however Digital Multimeter can do this job. But while using DMM to measure current one thing should be kept in mind that your circuit should be linear so that if you break the circuit to find current in series the current could not change in circuit.
Can you used cathode ray oscilloscope as television?
Yes, some could be used for analog monochrome TV but lots of extra circuits would be needed. Picture would be green. Cost of oscilloscope would likely be several times a portable analog TV of similar size, even before adding extra circuits.
A testing instrument that's used to measure electrical signals in a circuit and display them as waveforms on a screen is called?
an oscilloscope
