A) base current and emitter current. D) none of the above. represents organization of single computer containing a control unit, processor unit and a memory unit. C) collector current and emitter current. An oscilloscope displays a voltage waveform versus time and has the following components: 1) a screen to display a waveform, 2) input jacks for connecting the signal to be displayed, and 3) dials to control how the signal will be displayed. Bandwidth is the frequency range of the oscilloscope, usually measured in Megahertz (MHz). An oscilloscope display in which the screen base line is adjusted to represent the one way distance in a test piece is called a: (a) A scan display (b) B scan display (c) C scan display (d) D scan display. b) False It does this by measuring the voltage drop across a resistor and in the process draws a small current. c) 3 directions The cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent screen. ANSWER: D. Saw tooth voltage for the horizontal deflection of electron beam, ANSWER: B. The most typical use case is the display of voltage versus time, where nearly all phenomena can be converted to electrical signals by using an appropriate converter. An oscilloscope typically displays a given variable as a function of another variable. b) 4 directions Before describing what to look for in an digital oscilloscope, it is necessary to begin by at least touching on analog. Nominal values (nom.) D) a full-wave rectifier with a shorted diode. c) voltage and time A) collector current divided by … Ans : (b) 31. Sometimes, people get confuse between digital voltmeter and digital storage oscilloscope.They thought that both dealt with voltage. 1.3 show a plot of the typical output readings of an instrument when a sequence of input quantities are applied to it. a) 1 direction b) slow x-y plotter Spectrum analyzer is useful for analyzing the amplitude response of a device against frequency. E-tray: sample Computer-based simulation of a real work situation and replicates an email inbox which contains information relating to a particular issue. GATE CSE MCQs. a) actual representation Thus if the input voltage signal applied to the y-axis of C.R.O is sinusoidally varying and if x-axis represents the time axis, then the spot moves sinusoidally, and the familiar sinusoidal waveform can be seen on the screen of the oscilloscope. View Answer, 5. The 5 and 6 Series oscilloscopes may be configured to run the Windows operating system with an … On this page we'll introduce some of the important o-scope buzzwords you should be familiar with before turning one on. CRO gives the visual representation of time varying signals. Most electronics engineers will have used an analog scope at some time and will be familiar with its layout and operation. The focus of this article is on Digital Storage Oscilloscopes (DSOs) as they represent the majority of new oscilloscopes purchased today. CRO can’t display microseconds time. Participate in the Sanfoundry Certification contest to get free Certificate of Merit. Typically oscilloscope represents __________ Figure 1: Typical Oscilloscope Display . C.R.O gives __________ Computer Architecture MCQ DBMS MCQ Networking MCQ. Sanfoundry Global Education & Learning Series – Electrical Measurements. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Oscilloscope Lexicon. Oscilloscope is __________ An example of scientific data gathered by an oscilloscope. a) current and time One such oscilloscope is the Rohde & Schwarz RTC1000.
