示波器(CRT)的操作和应用说明书

The Oscilloscope: Operation andApplications1.The OscilloscopeOscilloscope Operation (X vs Y mode)An oscilloscope can be used to measure voltage. It does this by measuring the voltage dropacross a resistor and in the process draws a small current. The voltage drop is amplified andused to deflect an electron beam in either the X (horizontal) or Y (vertical) axis using anelectric field. The electron beam creates a bright dot on the face of the Cathode Ray Tube(CRT) where it hits the phosphorous. The deflection, due to an applied voltage, can bemeasured with the aid of the calibrated lines on the graticule.First we will consider the circuitry that amplifies and conditions the voltage to be measured (the “Amp” block in figure 1).Figure 1. X vs. Y Deflection Block Diagram of the CRT The deflection of the oscilloscope beam is proportional to the input voltage (after ac or dccoupling). The amount of deflection (Volts/Division) depends upon the setting of theAMPL/DIV control for that channel (see figure 2).The input signal can be ac or dc coupled. Ac coupling involves adding a series capacitor. This has the effect of blocking (removing) the dc bias and low frequency components of a signal.Dc coupling does not have this problem and therefore allows you to measure voltages rightdown to 0 Hz. Ac coupling is useful when you are trying to measure a small ac voltage that is “on-top” of a large dc voltage. A typical example is trying to measure the noise of a dc power supply.Figure 2. Amplifier Block DiagramAmplifier FeaturesAMPL/DIV - This abbreviated name varies but it is generally some short form of amplitude per division. The control is a simple voltage divider (attenuator) which is used to change the sensitivity of the oscilloscope. At a 1 volt/DIV setting, a deflection of one major division on the graticule represents a one volt change at the oscilloscope input.Calibrated voltage measurementsThe small knob within the AMPL/DIV control must be rotated clockwise into its detente position for the amplifiers to be calibrated. Otherwise the voltage/division will be some unknown value greater than what the dial indicates.INV - There is almost always a control which lets you invert one channel. This can be used along with the ADD function to subtract two voltages. This is necessary because the common input (black lead of the oscilloscope cable) can only be connected to a 0V node. If channel A has V1 + V2 and channel B has voltage V1 then the reading of channel A + (-channel B) = (V1 + V2) + (-V1) = V2Position - For each axis there is a control which lets you shift the electron beam. With this you can set the zero voltage point to anywhere that is convenient for you.Oscilloscope InputsThe input of the oscilloscope can usually be modelled as a resistance and a parallel capacitance (see figure 3). The resistance is usually 1M S but it and the capacitance can vary greatly. The total or effective capacitance includes the oscilloscope circuitry (approx. 30 pF), cables (approx. 30 pF/m) and stray capacitance. The resistance will draw current from the circuit while the capacitance will add an RC time constant with its associated time delay, frequency response and distortion of some waveforms.The common connection (black lead or shield) at the input of the oscilloscope goes to the metal case as the symbol by the input connector shows. Because of this, the common input can only be connected to a 0V point in the circuit. Since the common inputs for both the A and B channels are connected to the case, they are effectively shorted together.Figure 3. DC-coupled Oscilloscope Input Circuitand Frequency ResponseFigure 4. AC-coupled Oscilloscope Input Circuit andFrequency ResponseFrequency response is calculated or measured by applying a pure sinusoidal waveform to a circuit. The circuit response is the output voltage divided by the input voltage. This is a complex number that can also be expressed as a magnitude (gain) and phase.Due to limitations in the amplifiers, the oscilloscope's frequency response is limited. Themanufacturer simply lists the half-power point for the oscilloscope without any external effects.Half power is also called the -3dB point. At this point, the voltage has decreased to 70.7% of its maximum. This means that only one-half of the maximum power would be dissipated in aresistive load. Keep in mind that an oscilloscope that is rated at 20 MHz is usually only accurate to 4 MHz for non-sinusoidal waveforms before distortion becomes a problem.With ac coupling (figure 4), an oscilloscope has another series RC circuit. It acts like a high pass filter (HPF). If you are viewing low frequency signals when ac coupled, not only will you not be able to measure any dc offset, but you will also be removing some low frequency information.Oscilloscope Operation (Voltage vs Time)The main function of an oscilloscope is to show voltage vs time. This is done by applying a ramp (or sawtooth) waveform into the X-axis amplifier as shown in figure 5. During the rising edge of the ramp, the electron beam scans across the screen. When the voltage drops back to 0V, the beam is turned off and quickly goes back to its starting point. This is signified by a thick line when the beam is on and a thin one when it is off (blanked).To obtain a stable picture on the CRT screen, the ramp waveform has to be in phase with the signal that you want to observe. This is done with a triggering circuit. The triggering circuit allows the oscilloscope to draw repeatedly the same waveform over and over by identifying the same point on a repetitive waveform.Figure 5.A Ramp-driven X-axis inputFigure 6. A Triggering ExampleFigure 7. Several Triggering CyclesThe triggering circuit allows you to select a voltage (an analog value) and an edge or slope (positive or negative) for the triggering circuit to compare to the input waveform. When the two are equal, the circuit puts out a pulse. This pulse triggers the ramp waveform generator to do one cycle of its rising and falling edges. Once the ramp has started a cycle of increasing voltage, it can not be retriggered until it has completed the full ramp and returned to 0V. This is illustrated in figure 6 for a single cycle and in figure 7 for multiple cycles.Not only do you have control over the starting point of the ramp, but the amount of time that the ramp takes to reach its maximum voltage (the right hand side of the CRT screen) can be adjusted with the timebase control. In essence, you have a “window”. You can move the window to any point on a waveform with the triggering circuit and you can change the size of the window with the timebase.The time-base control allows you to set the time / division that the beams takes to scan acrossthe screen. Just like the voltage selector, there is a calibration knob in the middle of the control. Unless the vernier (calibration knob) is 'clicked' in to its most clockwise position, the time per division is unknown.When set to AUTO (automatic) triggering, the oscilloscope will always show a trace. However, when you use a manual triggering mode (DC, AC), many strange things can happen. For example, if the triggering voltage or level is set to +10V and the waveform never exceeds +5V, the triggering circuit will never trigger and the screen will stay blank.You may think that in a condition of no triggering, you would still have a bright dot on the screen because the electron beam would go to its 'home' or undeflected position. Since the oscilloscope is designed to work with a moving electron beam, a stationary beam can very quickly 'burn' a hole in the phosphorous coating of the screen. To prevent this, there is a ' blanking' circuit which turns off the electron beam. Blanking occurs when there is no triggering or when the electron beam is sweeping from the right edge back to the left side of the screen. Time measurements are done the same way as voltage measurements. As long as the timebase is calibrated you multiply the number of divisions by the number of seconds per division to get the total time difference. Phase measurements are done by comparing the measured time to the period of the waveform.Oscilloscope Two Channel OperationYou can view two voltage waveforms at once by using two Y-axis (vertical) input channels. The individual channels are sometimes labelled as '1' and '2' or as 'A' and 'B'. Since there is only one electron beam, you have to share its drawing time between both waveforms. This may be accomplished using either the chop or alternate modes.When in the chop mode (figure 8), the oscilloscope displays a little bit of channel A, then a little bit of B, then A, then B ....during a single sweep of the electron beam. If you increase the timebase to about 1:s/division, you can start to see the individual pieces as it chops between one channel and the other channel.Figure 8. Chop ModeIn the alternate mode (figure 9), the oscilloscope will sweep the electron beam twice across the screen. The first time it will draw the signal from channel A and the next time from channel B. At very low timebase settings, you can see it draw one channel and then the other in successive passes.Note: When you use the alternate function, the two waveforms that you see are from different points in time and the triggering circuit has to trigger twice.Figure 9.Alternate ModeFigure 10. A Simple Oscilloscope Block DiagramThe reason that you can see a non-flickering image on the screen is because the phosphorous coating on the CRT has persistence. In essence, the phosphorous acts like a low pass filter and averages several images that are drawn on the screen.By viewing two signals at a time, you can measure relative time differences. By combining a voltage and phase measurement (relative to the appropriate reference), you can measure a phasor value.With a two channel oscilloscope, you have the ability to trigger on each waveform andelectronically switch (chop or alt) between them as well. A block diagram of a oscilloscope has now become as shown in figure 10.Some oscilloscopes offer a way to alternately trigger as depicted in figure 11. When combined with alternate displaying, you can stably display two waveforms of any frequency by alternately showing each channel and triggering on the channel that is being drawn. This way, the oscilloscope is acting like a two beam scope with both waveforms triggering at the same voltage and slope. However, there is no way to know what the relationship is between one waveform and the other when using alternate triggering.Figure 11. Stable Triggering of Two Different FrequenciesIf you have two waveforms that do not have the same frequency, it is still possible to show them as two stable waveforms on a normal oscilloscope. In figure 11, you will notice that if the triggering occurs at the 'X', both waveforms are in phase (ie. at the same phase each time the timebase triggers). The condition for a stable display is not that two waveforms have to be of exactly the same frequency, but that when they are triggered, they have to be in phase.Or n A f1 = m A f2 where n, m are integers. That is not necessary, but it is sufficient. There are many other ways to achieve a stable trace when you consider that the trigger circuit will wait for the next triggering point. There is also a control on some oscilloscopes, called 'hold off', which allows you to add a delay between the end of the trace being drawn and the time when the triggering circuit starts to look for the next triggering point. That can be used to stabilize the display under some circumstances.Remember that all of this applies only for repetitive waveforms that are properly triggered. If the triggering is not stable, or the waveform is not repetitive, you will see a constantly moving image or several images offset and superimposed.A slightly more complicated block diagram of an oscilloscope, with the typical functions found in the laboratory, is illustrated in figure 12.AccuracyThere are many factors affecting the accuracy of oscilloscope measurements.There are errors due to the input channel voltage divider, timebase control, the use of magnifiers, the accuracy to which the CRT deflection can be read, beam thickness, temperature etc. The voltage divider error will be the same for all readings that are done on the same timebase and voltage range, but may be different each time the range is changed. Measurements over only two divisions can incur two to three times the error of those made over the centre eight divisions.If the phase angle is used in a trigonometric function, this error can be multiplied by the slope of the function. Consider that the tangent of a 1% phase error entered at 85 degrees is much worse (20%) than the same 1% error on a sine function (0.2%) at the same angle. To get a feel for this look at the Taylor expansion of the trigonometric functions.It is wise to consult the user manual for a particular instrument’s accuracy specifications.Figure 12. Oscilloscope Block Diagram2.Iwatsu Model SS-5702 OscilloscopeAccuracyThe Iwatsu SS-5702 oscilloscope is used in this laboratory. All measurements on the graticule should be made over as many divisions as possible. For simplicity, assume the Iwatsu SS-5702 oscilloscope’s error is ±5% for a measurement on either the vertical or horizontal scales over eight divisions.Front Panel ControlsThe front panel controls, shown in figure 13, will be described in the remainder of this section.Figure 13. The Iwastu SS-5702 OscilloscopeFront Panel ControlsThe power, trace rotation, intensity, focus, and scale illumination controls are located at the bottom centre.The vertical controls and input selection are on the left side.The horizontal controls and horizontal input selection are on the right side.The triggering selection section is at the bottom right.The power on/off, trace rotation, intensity, focus and scale illuminationTrace rotation has to be checked with just a straight line across the screen of the oscilloscope. The intensity should be adjusted to a mid point (or more clockwise).The focus of the beam can be done while observing the straight line display.The scale illumination can be adjusted to the operator’s preference.Vertical InputsVertical channels are used for measuring voltage.The beam is deflected vertically as a result of the signal being applied to the vertical input of the channel (CH).CH-1 and CH-2 are the labels for the two vertical inputs.Each channel has a position control, a range selection switch, a pull “x5” knob, a coupling selector switch (AC/GND/DC), and an input connector.Each channel Range switch (VOLTS/DIV) has a smaller knob in the middle of the Range Selector Switch. And there is an arrow showing that the Range Selector Switch is in the “CAL” position when rotated fully clockwise.In the centre of the two channel sections is the channel selection switch. You can choose to have CH-1, CH-2, both (DUAL), or ADD.In addition, CH-2 has a “Polarity” switch. You push the polarity switch in to “INVERT” the polarity of the signal being displayed. The “NORM” or out position is the normal position of the polarity switch.Horizontal InputsThe “EXT” (HORIZONTAL IN) can be supplied a voltage directly via the connector at the bottom right of the panel, or the Horizontal can be driven by an internal timebase circuit which generates the voltage.TimebaseIn the timebase mode, the horizontal signal is from an internal source which changes linearly with respect to time. Hence, the beam is deflected to give us a calibration of time for the horizontal scale.The position control, the pull “x5” magnifier switch, the time range selection switch, and the range “CAL” knob all affect the X-axis of the display.Trigger SourcesThe TRIGGER SOURCE may be selected from one of three sources, CH-1, CH-2, or EXT. Look at the bottom right of the control panel.Calibration SourceThe Calibration Source is an internal source, available on the oscilloscope.Look at the bottom right side of the front panel. The output is labelled 0.3 V.This is a 1000 Hz, square-wave ( the 50 % duty cycle is not accurate ).Figure 14.Differential Measurement Example3.Oscilloscope ApplicationsVoltage and Time MeasurementsNote:The oscilloscope measures divisions of deflection not voltage or time. From the divisions of deflection you can calculate the time or voltage.Differential MeasurementsAn important application of the oscilloscope is differential measurements. Such measurements are necessary because both vertical channels have one terminal connected to the chassis common (ie single ended). To measure a floating (off ground) voltage you have to use the “invert and add” feature of the oscilloscope. For example, in figure 14, to measure V1:Channel A measures (V1 + V2) relative to ground while channel B measures V2 relative to ground. By pushing the invert button you negate the voltage displayed on channel B. Then you can add the channels together with the “ADD” display mode. The waveform now displayed is (V1 + V2) + (- V2) = V1.Bandwidth (-3 dB) MeasurementThis measurement is easily done by first finding the maximum gain (max. VOUT / VIN atfrequency To) and adjusting the oscilloscope so that the sinewave fills seven divisions peak to peak. A -3dB point can be found by increasing and/or decreasing the frequency until the gain is reduced to /2 . If the input voltage has remained constant this will occur when the output voltage is five divisions peak to peak.The frequency is then simply read with a frequency counter or the oscilloscope. Not by reading the dial of the signal generator.RisetimeThe risetime indicates how quickly a circuit responds. The risetime is the time it takes a waveform to go from 10% of the voltage range to 90% of the voltage range. This is in response to a square wave and the output voltage must settle to a steady-state voltage (0% and 100%). Most oscilloscopes have dotted lines on the graticule marking the 10% and 90% points to aid in this measurement. Usually these dotted lines assume that 0% is the lowest line of the graticule and 100% is the highest line. The measurement, as shown in figure 15, also includes the risetime of the oscilloscope and the squarewave source.Figure.15 A Risetime and Phase MeasurementPhasePhase is most accurately measured when the waveform is as large as possible and the difference is measured at the zero crossings. Typically the timebase is uncalibrated so that a 180 degree section of the waveform is expanded to the full 10 divisions of the graticule. Then the sign of the phase can be determined by observing more than one period of both waveforms. Both waveforms must be symmetrical about the centre line of the graticule. The angle is determined by: phase = # of divisions * 180 degrees / 10 divisions.。
