示波器的使用方法示波器虽然分成好几类,各类又有许多种型号,但是一般的示波器除频带宽度、输入灵敏度等不完全相同外,在使用方法的基本方面都是相同的。

本章以SR-8型双踪示波器为例介绍。

(一)面板装置SR-8型双踪示波器的面板图如图5-12所示。

其面板装置按其位置和功能通常可划分为3大部分:显示、垂直(Y轴)、水平(X轴)。

现分别介绍这3个部分控制装置的作用。

1.显示部分主要控制件为:(1)电源开关。

(2)电源指示灯。

(3)辉度调整光点亮度。

(4)聚焦调整光点或波形清晰度。

(5)辅助聚焦配合“聚焦”旋钮调节清晰度。

(6)标尺亮度调节坐标片上刻度线亮度。

(7)寻迹当按键向下按时,使偏离荧光屏的光点回到显示区域,而寻到光点位置。

(8)标准信号输出 1kHz、1V方波校准信号由此引出。

加到Y轴输入端,用以校准Y 轴输入灵敏度和X轴扫描速度。

2.Y轴插件部分(1)显示方式选择开关用以转换两个Y轴前置放大器YA与YB 工作状态的控制件,具有五种不同作用的显示方式:“交替”:当显示方式开关置于“交替”时,电子开关受扫描信号控制转换,每次扫描都轮流接通YA或YB 信号。

当被测信号的频率越高,扫描信号频率也越高。

电子开关转换速率也越快,不会有闪烁现象。

这种工作状态适用于观察两个工作频率较高的信号。

“断续”:当显示方式开关置于“断续”时,电子开关不受扫描信号控制,产生频率固定为200kHz方波信号,使电子开关快速交替接通YA和YB。

由于开关动作频率高于被测信号频率,因此屏幕上显示的两个通道信号波形是断续的。

当被测信号频率较高时,断续现象十分明显,甚至无法观测;当被测信号频率较低时,断续现象被掩盖。

因此,这种工作状态适合于观察两个工作频率较低的信号。

“YA”、“YB ”:显示方式开关置于“Y A ”或者“YB ”时,表示示波器处于单通道工作,此时示波器的工作方式相当于单踪示波器,即只能单独显示“Y A”或“YB ”通道的信号波形。

break. So what does this mean to modern oscilloscopes?Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication Note 2As designs become faster and more complex, the need for long records, more bandwidth and higher sampling rate, will also increase. Record length is the number of samples an oscilloscope can digitize and store in a single acquisition. The longer the record length, the longer the time window the oscilloscope can capture with high timing resolution (high sample rate). The record length required for a specific application is directly affected by the bandwidth and sample rate. As bandwidth goes up, the sampling rate mustbe approximately five times higher to accurately capturethe signal’s high frequency content. As the sampling rate goes up, a given time window of signal acquisition requires more samples.For example, to capture 2 milliseconds of a 100 MHz signal at 5 GS/s requires a 10 million point record. (Divide2 milliseconds by the 200 picosecond sample interval.) Even at lower frequencies, there are many applications that require long records. Just capturing a single frame of NTSC video (two fields in a 1/30th of a second interval, at 100 MS/s to resolve all the luminance information) requires over3 million points (33 milliseconds divided by 10 nanoseconds). Capturing several seconds of bus traffic on a 1 Mb/sCAN bus to diagnose problems in an electro-mechanical system may require 10 million points for adequate resolution. These and a variety of other applications have driven and continue to drive the need for longer and more detailed data capture windows.Analyzing all that DataThe first digital oscilloscopes had very short record length. As such, it was easy to see everything the oscilloscope captured because it was all on the screen at one time. As oscilloscopes evolved and records got longer, horizontal scrolling was used to see all the data. This was not a big issue as you move from one screen’s worth of information to two, then up to four, eight, twenty, etc. However, as records became longer and longer with each generationof oscilloscope, the time required to look through all the data captured in a single acquisition grew longer and longer.We are now dealing with record lengths in the millions of points that represent thousands of screens worth of signal activity. By way of comparison, imagine trying to find what you’re looking for on the Internet without the assistance of your favorite search engine, web browser, or bookmarks.It would be like searching for a needle in a haystack. Until recently, this is what oscilloscope users faced with their long record length oscilloscopes. Clearly, the old solutions will no longer work.Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note3/oscilloscopes Wave Inspector ®Navigation and SearchAvailable on the MSO/DPO4000, DPO3000, andMSO/DPO2000 Series oscilloscopes, Wave Inspector ®controls make working with long records and extracting the answers you need from your waveforms a simple and efficient process.Zoom / PanMost digital oscilloscopes on the market today offer some form of zoom capability. However, the controls associated with the zoom view (zoom factor and position) are oftenburied in menus or multiplexed with other front-panelcontrols. For example, the zoom window’s horizontal position is typically controlled by the horizontal position knob on the front-panel. Once you’ve zoomed in on an event of interest, if you want to move the zoom window to another location in the acquisition it typically means either turning the horizontal position knob countless times to slowly move the window to the new location, or zooming back out, adjusting the window’s location and then zooming back in. Neither approach is efficient or intuitive. It becomes even less efficient when you have to navigate through menus just to access these basic zoom controls.Figure 1.Wave Inspector ®provides dedicated front-panel controls for efficient waveform analysis.Wave Inspector ®ControlsWave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NoteAs shown in Figure 1A, Wave Inspector provides a dedicatedtwo-tier front-panel Zoom / Pan knob for efficient waveformnavigation. The inner knob controls the zoom factor. Thefarther clockwise you turn it, the farther you zoom in. Turningit counter-clockwise zooms back out and ultimately turnszoom off.The outer ring is a force/rate sensitive pan control. Turningit clockwise pans the zoom window right on the waveform,counterclockwise pans it left. The farther you turn it, thefaster the zoom window moves across the waveform. InFigure 2, we can quickly navigate from one packet to thenext by simply turning the pan control in the desired direction.Even with a 10 million point aquisition, you can rapidly movethe zoom window from one end of the record to the otherin a few seconds, without ever having to change yourzoom factor.In Figure 2 we’re probing an I2C bus. The complete acquisitionis shown in the upper window and the zoomed portionis in the lower, larger window. In this case we’ve zoomedin to view the decoded address and data values for oneparticular packet.Figure 1A.Wave Inspector®provides dedicated front-panel zoomand pan controls.4Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note5/oscilloscopes Figure 2.Navigating through a long acquisition of an I 2C bus.Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NotePlay / PauseMany times when debugging a problem, you don’t know what’s causing the problem so you’re not sure what to look for in the waveform you’ve acquired. However, you know you’ve captured the time window that contained the problem and you now need to look through the data you’ve captured to see if you can find the issue. Again, on most modern oscilloscopes this is done by manually turning the horizontal position knob countless times to inspect the acquired waveforms for any suspicious activity. Wave Inspector®controls help in this area as well. You can simply press the Play button on the front-panel to have your zoom window automatically pan across the waveform. Play speed and direction are adjusted using the intuitive pan control. The farther you turn the pan control the faster the waveform plays by. This allows hands-free playback so you can concentrate on what’s important – the waveform itself. In the I2C example (Figure 2), you could play the waveform while watching the decoded address and data values to monitor activity on the bus. When you spot the event you’re looking for simply press the Play/Pause button again to stop the waveform.6Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note7/oscilloscopes MarksWhile looking for the source of the problem, you may find numerous areas of the waveform that either warrant further investigation or are indicative of something happening in the device under test that you want to use as a reference point during the rest of your analysis. For example, assume you need to make timing measurements associated with the latency from when a driver presses the Passenger Window Down switch on the driver’s door panel to when the passenger window actually starts to move. The first event you’ll want to find in the acquisition is when the switch was pressed. The next may be when the CAN module in the driver’s side door issues the command to the CAN module in the passenger door. The last event may be when the motor engaged in the passenger door and the window started to move. Wouldn’t it be nice to mark each of these locations on the waveform so you can quickly jump back and forth between the areas of interest for timing measurements? With the Tektronix Wave Inspector ®Navigation Series you can.In Figure 3, Channel 1 is the output of the switch in the driver’s door, channel 2 is the CAN bus, and Channel 3 is monitoring the motor drive in the passenger door.Wave Inspector®Navigation and Search: Simplifying Waveform Analysis Application NoteWe’ve set the oscilloscope up to trigger on the packet of interest by specifying the appropriate Identifier and Data. Next, we’ve used the front-panel Set / Clear Mark button to mark each of the events of interest on the waveform. These user marks are shown as solid white triangles along the top edge in both the upper and lower windows. The rising edge on channel 1 indicates when the switch was pressed. The trigger event is the CAN module in the driver’s door issuing the command and the window beginning to move is the transition on Channel 3. Using the front-panel Previous and Next buttons we can instantly jump between marks to place cursors for quick and easy latency measurements. In Figure 3, we find that the total time from the press of the switch to window movement is 58.8ms, well within the amount ofacceptable delay.Figure 3.Placing marks on the waveform to assist in latency measurements on a CAN bus.8Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication NoteSearch & MarkIn addition to placing marks on waveforms manually,Wave Inspector ®has the power to search through the entire acquisition and automatically mark every occurrence of a user-specified event. For example, imagine you are capturing laser pulses. The laser fires approximately every 20 µs, with each pulse being only 15 ns wide. You want to look at multiple pulses to characterize their shape and to make precise timing measurements between them, but to navigate from one to the next you need to sift through close to 20 µs of dead time. Then you need to repeat this for every other pulse in the acquisition. Clearly, it would be desirable to be able to move from pulse to pulse instantly without having towaste time “twiddling” a position knob.9/oscilloscopes Figure 3A.Wave Inspector's ®powerful Search capability allows you to find every occurrence of a user-specified event in the acquisition.Previous ButtonNextWave Inspector®Navigation and Search: Simplifying Waveform Analysis Application NoteA very simple search setup that looks for rising edges that cross a threshold of 300mV is illustrated in Figure 4. Marks generated by the search are shown as hollow white triangles along the top edge in both the upper and lower windows. This search resulted in 105 marks being placed throughout the record. Now all you have to do is press the front-panel previous and next buttons to jump from one pulse to the next, no adjustment of zoom scale or positionis required!Figure 4.Wave Inspector®marking every pulse that crosses 300mV in a long acquisition.10Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NoteWave Inspector’s®Search goes well beyond simple edge searches. Imagine the chip you’re working with has an indeterminate output every so often that’s causing the overall system to crash. You suspect that it’s a metastability issue caused by Setup & Hold violations. In a matterof seconds, you can specify search criteria to have the oscilloscope automatically find every occurrence in the acquisition where setup and hold times you specify were violated. In this case, the part we’re using has published setup and hold times of 12 ns and 6 ns, respectively. To have the oscilloscope automatically find violations of these limits, we simply need to tell it clock is on Channel 1, Data is on Channel 2, set the thresholds, and enter the desired setup and hold times. The oscilloscope then checks the timing relative to every clock edge throughout the entire acquisition and marks the occurrences that violate the specified setup and hold times. In Figure 5, our search resulted in sixviolations. The six events are marked with hollow white11/oscilloscopes Figure 5.Setup & Hold violation search results in six occurrences found.Wave Inspector®Navigation and Search: Simplifying Waveform Analysis Application Notetriangles in the upper window. The lower window is showing a zoomed in view of one of the violations. It’s clear that the narrow negative pulse on the data line is violating the 12 ns setup time.We’ve found the metastability source without having to manually scroll through the waveform and without havingto use cursors to measure anything. You can even perform worst case checks by adjusting the setup and hold times and seeing how many events Wave Inspector®finds. For example, you can set the hold time to zero and then reduce the setup time until only one event is found.1Another powerful search capability provided by Wave Inspector is searching for data in a bus. You can use the front-panel bus buttons to define your signals as an I2C, SPI, CAN, RS-232, or parallel bus. Then the oscilloscope will decode the bus into packets, displaying the informationin a meaningful form. You can trigger on or search for datain the packets. (Requires optional application modules.) 121The MSO4000, MSO2000, and DPO2000 Series oscilloscopes can search for setup & hold violations on every channel in the oscilloscope.Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NoteWhile this triggering is critical to isolate the time window that contains the problem, it’s highly likely that you’ll need to view bus activity over many packets to understand what’s going on at a system level. The bus search feature enables you to specify packet level criteria and mark every occurrence of it in the record for quick viewing,navigation and analysis. Continuing the earlier CAN example, in Figure 6 we’ve searched for every message in a long acquisition of a CAN bus with the specific Identifier (549) and Data (A1) values we’re interested in.Wave Inspector®found four messages in the acquisition that met the criteria. Again, moving the zoom window from one occurrence to the next is as simple as pressing the previous and next buttons on the front-panel. And because the oscilloscope is decoding the packets for you, you can instantly see all the relevant information without having to manually decode from analog waveforms.In addition to the examples provided above, Wave Inspector®can search for many other types of events. The full list ofsearch capabilities is shown in Table 1.13/oscilloscopes Figure 6.Searching for specific Identifier and Data values in CAN messages.Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note14Table 1.Search events.Search Type DescriptionEdge Searches for edges (rising or falling) with a user-specified threshold level.Pulse Width Searches for positive or negative pulse widths that are >, <, =, or ≠ a user-specified pulse width. RuntSearches for positive or negative pulses that cross one amplitude threshold but fail to cross a second threshold before crossing the first again. Search for all runt pulses or only those with duration >, <, =, or ≠ a user-specified time.LogicSearch for a logic pattern (AND, OR, NAND, or NOR) across multiple waveforms with each input set to either High, Low, or Don’t Care. Search for when the event goes true, goes false or stays valid for >, <, =, or ≠ a user-specified time. Additionally, you can define one of the inputs as clock for synchronous (state) searches.Setup & Hold Search for violations of user-specified Setup and Hold times.Rise / Fall Time Search for rising and/or falling edges that are >, <, =, or ≠ a user-specified time.BusI 2C: Search for Start, Repeated Start, Stop, Missing Ack, Address, Data or Address & Data.SPI: Search for SS Active, MOSI, MISO, or MOSI & MISO.CAN: Search for Start of Frame, Type of Frame (Data, Remote, Error, Overload), Identifier (standard or extended), Data, Identifier & Data, End of Frame, or Missing Ack.LIN: Search for Sync, Identifier, Data, Identifier and Data, Wakeup Frame, Sleep Frame or Errors such as Sync, Parity, or Checksum Errors.RS-232/422/485/UART: Search for Tx Start Bit, Rx Start Bit, Tx End of Packet, Rx End of Packet,Tx Data, Rx Data, Tx Parity Error and Rx Parity Error. Parallel: Search for data value.FlexRay (MSO/DPO4000 Series only): Search for Start of Frame, Type of Frame (Normal, Payload, Null,Sync, Startup), Identifier, Cycle Count, Complete Header Field, Data, Identifier and Data, End of Frame or Errors such as Header CRC, Trailer CRC, Null Frame, Sync Frame, or Startup Frame Errors.Multiple SearchesAn obvious question at this point is,“What if I want to perform another search, but don’t want to lose the results (marks) from my first search?”Simply select the Save All Marks menu selection and you’ll see that the hollow white triangle search marks become filled in, appearing the same as marks placed with the front-panel Set Mark button. These marks are now saved on the waveform and a new search can be performed. You can do this as many times as you like, effectively creating unlimited searching ability. Of course, if you would like to start over with a clean slate you can press the Clear All Marks button to remove all marks from the waveform or you can remove any single mark using theSet/Clear Mark front-panel button.Search Interaction with TriggerTwo other powerful and time-saving capabilities are included in the Search menu: the ability to copy trigger settings to search and copy search settings to trigger. Copying the current trigger settings to the search menu is most useful when you want to search through the acquisition to see if there are any other occurrences of the trigger event in the captured data. Alternatively, copying search settings to the trigger menu is most useful when you’ve found an event in your data and you want to reacquire new data using that event as the trigger criteria.ConclusionModern digital oscilloscopes can capture massive amounts of data. Until now, searching through that data has beena time-consuming and frustrating process. With Tektronix Wave Inspector®Navigation and Search, you can extract the answers you need with efficiency and precision and unlikeany other oscilloscope.Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication Note15/oscilloscopes MSO/DPO4000 Series DPO3000 Series MSO/DPO2000 Series Bandwidth 1 GHz, 500 MHz, 350 MHz500 MHz, 300 MHz, 100 MHz200 MHz, 100 MHzChannels (analog) 2 or 4 analog 2 or 4 analog 2 or 4 analogChannels (digital)16 digital (MSO series)–16 digital (MSO series)Record Length10 M 5 M 1 M(All Channels)Sample Rate 5 GS/s*, 2.5 GS/s 2.5 GS/s 1 GS/sDisplay10.4 in.
