AnswersDriveAn oscilloscope's trigger function is important to achieve clear signal characterization, as it synchronizes the horizontal sweep of the oscilloscope to the proper point of the signal. The trigger control enables users to stabilize repetitive waveforms as well as capture single-shot waveforms.
1
What is sweeping in an oscilloscope?
An analog oscilloscope consists of a cathode ray tube (CRT), sweep generator and a vertical amplifier as shown in figure 5. The sweep generator causes an electron beam in the CRT to sweep horizontally across a phosphorescent screen.
2
What is sampling oscilloscope?
A sequential equivalent-time sampling oscilloscope, sometimes simply called a “sampling scope,” measures the input signal only once per trigger. The next time the scope is triggered, a small delay is added and another sample is taken.
3
What do you mean by edge triggering?
Edge Triggering: In edge triggering the circuit becomes active at negative or positive edge of the clock signal. For example if the circuit is positive edge triggered, it will take input at exactly the time in which the clock signal goes from low to high.
4
What is meant by trigger circuit?
(electronics) A circuit or network in which the output changes abruptly with an infinitesimal change in input at a predetermined operating point. Also known as trigger. A circuit in which an action is initiated by an input pulse, as in a radar modulator. bistable multivibrator.
5
What is an external trigger oscilloscope?
1. Brief explaination of external trigger. Trigger is an important portion of a oscilloscope. It is used to synchrounize captures to generate stable waveform displays and help to capture rarely appear signals. Most oscilloscopes contain a trigger that uses internal signal, i.e. the signal being viewed, as trig source.
6
What is meant by time base generator?
A time base generator, or timebase, is a special type of function generator, an electronic circuit that generates a varying voltage to produce a particular waveform.
7
What are the functions of an oscilloscope?
An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time.

How does trigger work in oscilloscope?
An oscilloscope's trigger function is important to achieve clear signal characterization, as it synchronizes the horizontal sweep of the oscilloscope to the proper point of the signal. The trigger control enables users to stabilize repetitive waveforms as well as capture single-shot waveforms.

How does a cathode ray oscilloscope works?
The CRO recruit the cathode ray tube and acts as a heat of the oscilloscope. In an oscilloscope, the CRT produces the electron beam which is accelerated to a high velocity and brings to the focal point on a fluorescent screen. The low voltage is used for the heater of the electron gun to generate the electron beam.
10
What is the use of sweep generator?
A sweep generator is a piece of electronic test equipment similar to, and sometimes included on, a function generator which creates an electrical waveform with a linearly varying frequency and a constant amplitude. Sweep generators are commonly used to test the frequency response of electronic filter circuits.
11
What is Sweep time?
Sweep speed (also referred to as sweep time) may be interpreted and specified in a multitude of ways. In general sweep, speed refers to the time required for a vector network analyzer (VNA) to complete one sweep of the source and acquire data over the defined frequency range.
12
What is sweep speed oscilloscope?
Sweep Speed. Sweep speed indicates how fast the trace can sweep across the oscilloscope screen, making it possible to see fine details. The sweep speed of an oscilloscope is represented by time (seconds) per division.
13
What is a sweep signal?
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly used in sonar and radar, but has other applications, such as in spread-spectrum communications.
14
What is meant by frequency sweep?
Radio frequency sweep or "frequency sweep" or "RF sweep" refer to scanning a radio frequency band for detecting signals being transmitted there. As the frequency of the receiver is changed to scan (sweep) a desired frequency band, a display indicates the power of the signals received at each frequency.
15
What is a chirp phone?
A chirp is a signal in which the frequency increases or decreases with time. Chirp may also refer to: Chirp (magazine), a Canadian magazine for children ages 3 to 6. Chirp (bird call), an onomatopoeic word for certain bird calls. Chirp (phone), a walkie-talkie service on Sprint-Nextel's iDEN-phones.
16
What is the use of an oscilloscope?
Oscilloscopes are used to observe the change of an electrical signal over time, such that voltage and time describe a shape which is continuously graphed against a calibrated scale. The observed waveform can be analyzed for such properties as amplitude, frequency, rise time, time interval, distortion and others.
17
What is the bandwidth of an oscilloscope?
∎ High-speed digital, serial communications, video and other complex signals can therefore require scope bandwidths of 500 MHz or more. Bandwidth is defined as the frequency at which a sine-wave input signal is attenuated to 70.7% of its true amplitude (the -3 dB or 'half-power' point, shown here for a 1 GHz scope).
18
Is Cro from Germany?
Carlo Waibel, better known by his stage name Cro (born January 31, 1990), is a German rapper, singer, producer and designer, who is represented by Chimperator Productions. He describes his music as a mixture between pop and rap, which he calls "Raop".
19
What is the function of a generator?
A function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave , square wave, triangular wave and sawtooth shapes.
