CAUTION Do not use too much liquid in cleaning the oscilloscope. Water can enter the Infiniium front panel, damaging sensitive electronic components. 26 2 Working in Comfort Working in Comfort To optimize your comfort and productivity, it is important that you set up your work area correctly and use your Infiniium oscilloscope properly. With that in mind, we have developed some setup and use recommendations for you to follow based on established ergonomic principles. Improper and prolonged use of keyboards and input devices are among those tasks that have been associated with repetitive strain injury (RSI) to soft tissues in the hands and arms. If you experience discomfort or pain while using the oscilloscope, discontinue use immediately and consult your physician as soon as possible. For more information on RSI, read the “About Repetitive Strain Injury” section, next. Please study the recommendations offered here in this chapter. Included there are references to relevant parts of international standards, regulations, and guidelines, such as ISO 9241 and the European Community Display Screen Equipment directive. You may also consult your employer’s human resources department or other relevant departments for guidance specific to your company. 28 Working in Comfort About Repetitive Strain Injury What is RSI? What causes RSI? What if I experience discomfort? Because your comfort and safety are our primary concern, we strongly recommend that you use the Infiniium oscilloscope in accordance with established ergonomic principles and recommendations. Scientific literature suggests that there may be a relationship between injury to soft tissues— especially in the hands and arms—and prolonged improper use of keyboards or other equipment requiring repeated motions of the hands and forearms. This literature also suggests that there are many other risk factors that may increase the chance of such injury, commonly called Repetitive Strain Injury. Repetitive Strain Injury (RSI—also known as cumulative trauma disorder or repetitive motion injury) is a type of injury where soft tissues in the body, such as muscles, nerves, or tendons, become irritated or inflamed. RSI has been a reported problem for those who perform repetitive tasks such as assembly line work, meatpacking, sewing, playing musical instruments, and computer work. RSI also has been observed in those who frequently engage in activities such as carpentry, knitting, housework, gardening, tennis, windsurfing and lifting children. The specific causes of RSI have not been established. Nevertheless, the incidence of RSI has been associated with a variety of risk factors, including: • Too many uninterrupted repetitions of an activity or motion. • Performing an activity in an awkward or unnatural posture. • Maintaining static posture for prolonged periods. • Failing to take frequent short breaks. • Other environmental and psychosocial factors. In addition, there have been reports associating the occurrence of RSI with the use of keyboards, mice, and other input devices. Also, certain medical conditions, such as rheumatoid arthritis, obesity and diabetes, may predispose some people to this type of injury. If you are experiencing any discomfort, seek professional medical advice immediately. Typically, the earlier a problem is diagnosed and treated, the easier it is to resolve. 29 Working in Comfort Mice and Other Input Devices Various aspects of using mice and other input devices may increase your risk of discomfort or injury. Observing the following recommendations may reduce that risk. • Try to keep your hand, wrist, and forearm in a neutral position while using your mouse or other input device. • If you use your thumb to rotate the ball on a trackball or spaceball, keep it in a relaxed, natural shape, and maintain a neutral posture in your hand, wrist, and forearm. • Hold the mouse gently by draping your fingers over it. Keep your hand relaxed and fingers loose. Do not grip the mouse tightly. • It takes very little pressure or force from your fingers to activate the buttons or scroll wheel on your mouse, scrolling mouse, trackball, or other input device. Using too much force can place unnecessary stress on the tendons and muscles in your hands, wrists, and forearms. • If you are using a scrolling mouse, be sure to keep your fingers and hand in a relaxed, neutral position when activating the scroll wheel. Also, this type of mouse features software that can minimize the number of mouse movements or button clicks. • When using a mouse, trackball, or other input device, position it as close to the keyboard as possible, and keep it at the same level as you do not have to stretch while using it. • Be sure to keep your mouse and trackball clean. Regular removal of accumulated dust and dirt helps ensure proper tracking and reduces unnecessary hand and wrist motions. 30 3 Using the Oscilloscope Using the Oscilloscope The topics covered in this chapter are very basic controls. For more detailed explanations of controls not found in this chapter, consult the built-in information system loaded on your oscilloscope (Help > Contents). The Infiniium Oscilloscope is designed to be easy to use. • The familiar front-panel oscilloscope interface with knobs and keys is optimized for the most common kinds of troubleshooting tasks and basic measurements. See “Using the Front Panel”. • The Infiniium oscilloscope application’s graphical interface with menus, windows, dialog boxes, and toolbars provides easy logical access to dozens of configuration and analysis tools, making it easy for you to set up and make the most complex measurements. See “Using the Graphical Interface”. • The Infiniium oscilloscope application also provides online help, which gives detailed information on using the oscilloscope. See “Accessing the Online Help”. 32 Using the Oscilloscope Using the Front Panel The Infiniium 9000 oscilloscope front panel gives you direct access to the functions needed to perform the most common measurements, using a traditional oscilloscope interface. Knobs and keys let you directly set vertical and horizontal parameters. In addition, the front panel has a set of LED (LightEmitting Diode) indicators; by using these and the display, you see the oscilloscope’s configuration at a glance. You can also push many of the front panel knobs to activate various modes such as vernier scaling (fine scaling). The oscilloscope uses color consistently throughout the front panel and user interface. For example, the color of the knob for channel 1 is the same color as the waveform for channel 1. All configuration items and values related to channel 1 are displayed in the same color. 33 Using the Oscilloscope Front Panel Figure 3-1 shows a typical Infiniium 9000 Series oscilloscope front panel. Figure 3-1 Selection knob (push to toggle selection) Run/Stop control section Horizontal controls (time/div, position, etc.) Trigger controls Turn digital channels on/off Turn serial decode on/off Color coded controls for each analog oscilloscope channel Infiniium Oscilloscope Front Panel 34 Using the Oscilloscope Using the front panel, you can configure the oscilloscope for most troubleshooting tasks. The control categories are: • Run controls • Horizontal controls • Trigger controls • Vertical controls • Marker and Measurement controls 35 Using the Oscilloscope Acquisition Run Controls Using the acquisition run controls, you control whether the oscilloscope is running or stopped. You can also put the oscilloscope into Single mode where only one acquisition is acquired before the oscilloscope stops. Horizontal Controls Using the horizontal controls, you configure the oscilloscope’s horizontal scale (time per division) and horizontal position of the waveform. You can also view a magnified section of the waveform using the Zoom window, which uses software to expand part of the acquisition memory. Several other keys in this section do not pertain directly to horizontal controls. For example, the [Autoscale] key allows you to reset the oscilloscope to its default setup and automatically configure the oscilloscope for the current input signals. Also, the [Clear Display] key erases the waveforms from the display and resets such things as measurement statistics and averaging. The [Touch] key enables or disables the touch screen. The [Default Setup] key returns the oscilloscope to a known state. Trigger Controls Using the trigger controls, you set the conditions on which the oscilloscope will trigger and acquire an input signal. You can set up a variety of trigger conditions. Edge and advanced triggers can be selected from the front panel, and the parameters for edge triggering can be set up here as well. The advanced trigger parameters must be set up using the graphical interface. Trigger configuration settings you make using the graphical interface are reflected in the front-panel status indicators, and will remain set unless you change them (either using the front panel or the graphical interface) or press the [Default Setup] key. See “Using the Graphical Interface” for information on accessing the graphical interface. 36 Using the Oscilloscope Vertical Controls Using the vertical controls, you set the vertical scaling (volts per division) and vertical offset. You can also turn the display on or off for a particular channel. Additionally, this section has a set of LEDs per channel that tell you what the input impedance is for the channel, what the coupling is for the channel, and whether or not Bandwidth Limit is enabled. Marker and Measurement Controls Using the marker and measurement controls, you control two sets of markers within the oscilloscope graticule. You use markers to make more accurate measurements of waveform events than you could make visually. Both time and voltage differences between the markers are updated continuously on the screen. By default, the markers track the source waveform. Voltage measurements from the markers are the value of the waveform at the time set with the marker position control. The [Multi Purpose] key can be customized in the GUI to perform a variety of operations (under Utilities > Customize Multipurpose). Pressing this key will then carry out the operation you specify. 37 Using the Oscilloscope To set the oscilloscope to a known starting condition • Press the [Default Setup] key. You can set up the oscilloscope for many different kinds of complex measurements. To easily reset the oscilloscope to a known measurement configuration, use the [Default Setup] key. If you use the [Default Setup] key, you can select Control > Undo Default Setup to return the oscilloscope to its original configuration. Save the Current Oscilloscope Configuration Before using [Default Setup], you may want to save the current oscilloscope configuration for later use. See the online help (described in chapter 4) for instructions on saving and recalling setups, and for information on the exact configuration that is set when you press [Default Setup]. 38 Using the Oscilloscope To start and stop waveform acquisition The [Run/Stop] key is green when the oscilloscope is acquiring data, and red when it is stopped. • To start a waveform acquisition, press the [Run/Stop] key. The oscilloscope begins acquiring data. When it receives a trigger signal, it finishes acquiring data, updates the display, then starts another acquisition cycle if it is in triggered (Trig’d) or auto trigger (Auto) mode. • To stop waveform acquisition, press the [Run/Stop] key. The oscilloscope stops acquiring data. Whatever data was last acquired remains on the screen. • To make a single acquisition, press the [Single] key. The [Single] key is lit yellow while the acquisition takes place. When the single acquisition is complete, the [Single] key is unlit and the [Run/Stop] key turns red. 39 Using the Oscilloscope To clear the waveform display • Press the [Clear Display] key. The oscilloscope clears the waveform display. If the oscilloscope is in Run mode and is receiving triggers, it will update the display as it collects new waveform data. Clearing the waveform display also resets averaging, infinite persistence, color grade persistence, histogram, mask testing, and measurement statistics. 40 Using the Oscilloscope To turn an analog channel on or off • To turn an analog channel on, press the channel number key in the Vertical section until it is illuminated. To turn it off, press the channel number key again. If you are not using a particular analog channel, you can turn it off. This simplifies the waveform display and also increases the display update rate. While an analog channel is turned off, data acquisition continues for that analog channel. Thus, you can still use the analog channel as a source for functions. Using an Analog Channel as External Trigger Any analog channel can be used as a trigger source. If you need an external trigger but do not need all analog channels, you can use an analog channel as an external trigger without displaying it by turning the analog channel display off. 41 Using the Oscilloscope To turn the digital channels on or off • To turn the digital channels on, press the [Digital] key on the front panel. To turn them off, press the key again. 42 Using the Oscilloscope To adjust the analog channel’s vertical scale and offset • To make the waveform bigger, turn the vertical scale knob clockwise. To make it smaller, turn the knob counter-clockwise. The vertical scale knob is the larger of the two knobs for a channel. It is marked with a set of sine wave symbols. Decreasing the vertical scale makes the waveform bigger. There are fewer volts displayed per division. Increasing the vertical scale makes the waveform smaller. There are more volts displayed per division. • To move the waveform toward the top of the display, turn the vertical offset knob clockwise. To move it toward the bottom of the display, turn the knob counter-clockwise. The vertical offset knob is the smaller of the two knobs for a channel. It is marked with a set of arrows. 43 Using the Oscilloscope To adjust horizontal scale and horizontal position • To stretch the waveform horizontally, turn the horizontal scale knob clockwise. To shrink it horizontally, turn the knob counter-clockwise. The horizontal scale knob is the larger of the two horizontal control knobs. It is marked with a set of sine wave symbols. Stretching the waveform means there are fewer seconds displayed per division. Shrinking the waveform means there are more seconds displayed per division. • To move the waveform to the right, turn the horizontal position knob clockwise. To move the waveform to the left, turn the horizontal position knob counter-clockwise. Moving the waveform to the right shows more of the pre-trigger data (data acquired before the trigger event). Moving the waveform to the left shows more of the post-trigger data (data acquired after the trigger event). The horizontal position knob is the smaller of the two horizontal control knobs. It is marked with a set of arrows. There is a detent programmed into the software so there is a momentary pause at zero while you are turning the knob. Continuing to turn the knob will move the horizontal position through zero. 44 Using the Oscilloscope To magnify a part of the waveform using Zoom • To turn on zoom, press the [Zoom] key. To turn it off, press the [Zoom] key again. The waveform display area splits into two regions. The top one is the main timebase. The bottom is the zoomed timebase, which represents a software expansion of the acquired waveform data. A section of the waveform in the main sweep window is highlighted to indicate the part shown in the delayed sweep window. The horizontal scale and horizontal position controls now change how the waveform is shown in the zoom window. The horizontal scale will change the amount of magnification, while the position will change the part of the waveform in the main window that is shown in the zoomed window. 45 Using the Oscilloscope To set the oscilloscope to trigger on an edge 1 Press and release the [Source] key until the desired source LED is illuminated. You can choose any of the channels, the Aux, or Line as the source for an edge trigger. 2 Press the [Slope] key until the desired slope LED is illuminated. You can have an edge trigger on a rising or falling edge. 3 Press the [Sweep] key until the Trig’d LED is illuminated. The oscilloscope will wait for the edge before initiating a sweep. 4 Turn the [Level] knob to adjust the voltage level at which the oscilloscope will trigger. 46 Using the Oscilloscope To use the markers • • • • Markers make it easier to make precise measurements because the marker measurement readouts show exact voltage and time positions for the markers. The measurements are based on actual waveform data from the acquisition system, not on approximations based on the display position, so you can be sure that the values are highly accurate. To select the type of marker mode that you want to use, press the [Markers] key and select the mode in the Markers Setup dialog box that appears. To turn on Marker A, press the Position knob until the marker that you want to move appears in the pop-up dialog box. Marker A has a solid line pattern on the waveform display. It is associated with the first available source on the display. To turn on Marker B, press the Position knob until the marker that you want to move appears in the pop-up dialog box. Marker B has a dashed line pattern on the waveform display. It is associated with the first available source on the display. To move a marker, turn the Position knob. In Measurement Marker mode, the marker position cannot be changed. 47 Using the Oscilloscope To use the quick measurements The action taken when the [Multi Purpose] key is pressed depends on the feature selected in the Customize Multipurpose dialog box. The default feature is QuickMeas (quick measurements), which is described as follows. • To turn on the quick measurement display, press the [Multi Purpose] key. The five preset measurements defined in the Quick Measurement configuration are enabled and results are displayed on the screen for the first waveform source. The default measurements are: Vp-p, Period, Frequency, Rise time, and Fall time. • To measure parameters for another waveform, press the [Multi Purpose] key until that waveform is the one shown in the measurement readout. Continuing to press the [Multi Purpose] key cycles through each of the waveforms available. • To turn off the quick measurement display, press and release the [Multi Purpose] key until the measurements are turned off. The measurement results disappear from the screen. See the Infiniium application’s online help (described in Chapter 4) for information on how to configure the quick measurement capability, using the Customize Measurement feature of the graphical interface. 48 Using the Oscilloscope To enable or disable the touch screen • To enable or disable the touch screen, press the front panel [Touch] key. 49 Using the Oscilloscope Using the Graphical Interface With the graphical interface for the Infiniium Oscilloscope, you can access all the configuration and measurement features of the oscilloscope through an easy-to-use system of menus, tool bars, dialog boxes, icons, and buttons. 50 Using the Oscilloscope Graphical User Interface The graphical interface looks like the following two figures. Figure 3-2 Access the Channel Setup dialog box Turn this channel on or off Set vertical scaling Memory bar— highlighted area shows how much of acquisition memory is displayed on the screen Menu bar Measurement toolbar Access the Digital Setup dialog box This button minimizes the oscilloscope application Infiniium Oscilloscope Top of Display 51 Using the Oscilloscope Figure 3-3 Single See more measurements Turn off any measurements that are running (use Clear display to reset/restart measurement statistics) Run Stop Clear display Print screen Set horizontal scale Access the Horizontal Setup dialog box Set horizontal position (delay) Access the Trigger Setup dialog box Set trigger level Waveform Brightness Infiniium Oscilloscope Bottom of Display To make it easy to see which controls affect each waveform, the oscilloscope uses color consistently throughout the graphical interface. These colors match the ones used on the front panel channel inputs. For example, the color of the waveform for channel 1 matches the color for that channel. If channel 1 is the trigger signal, all of the trigger configuration items, including the trigger level reference icon (at the right side of the waveform display area), will match that color. The buttons associated with that channel, vertical scaling and offset settings, ground reference indicator, and measurements done on that channel also have the same color. All changes made to the front panel settings are reflected in the graphical user interface, and changes made using the graphical interface are reflected in the front panel where applicable. Use whichever interface is easiest for you in a 52 Using the Oscilloscope particular measurement situation. For example, it might be easiest to set a coarse vertical scale using the knobs, then fine-tune the setting using the graphical user interface. The graphical interface is arranged so that the most common functions affecting the waveform display are located around the edge of the waveform viewing area. These include the measurement toolbar, horizontal and trigger toolbar, and vertical toolbar. Measurement Toolbar The measurement toolbar contains icons representing the most commonly used automatic measurements built into the oscilloscope. Drag and Drop Measurements By dragging one of the measurement icons to a waveform in the waveform display area, you can make that measurement on the waveform. As you drag a measurement icon around the screen, the icon outline changes color to match the color of the closest waveform. This makes it easy to see which waveform will be measured when you drop the icon. For those measurements that are done on waveform features, the measurement is made at the feature closest to the location where you dropped the icon. For example, you might want to measure the rise time of the fifth rising edge; dropping the rise time measurement icon at that edge will cause the measurement to be made on that edge. You can also make a measurement by simply clicking the icon on the measurement toolbar, then selecting the source to be measured in the dialog box that appears. When you start a measurement this way, any measurements on waveform-specific features will measure the feature closest to the horizontal reference indicator. Each waveform can have multiple simultaneous measurements and the measurements can all be of the same type, if desired. For example, you can have three pulse width measurements on different parts of the same waveform. Geometric Measurement Indicators For each measurement currently running, a geometric indicator at the measurement location on the waveform corresponds to an identical indicator in the measurement results readout. This makes it easy for you to verify that the readout shows results for the correct waveform and the correct feature on that waveform. See figure 3-25 for an example. Tool Tips To find out what a particular measurement tool does, move the mouse pointer over it for a moment. A small pop-up window will appear that describes the measurement. 53 Using the Oscilloscope Other Measurement Features More measurements are available than will fit on a single toolbar. Click the More (1 of 2) or More (2 of 2) icons to see other measurements. Clicking Delete All will remove all selected measurements from the waveform display area. Tab Display Area The tab display area is located beneath the waveform viewing area. Figure 3-4 Minimize and maximize tabs buttons Tab Display Area The display area shows information and statistics for the particular tab that is selected. The type of markers that are shown in the waveform viewing area depend on the tab that you have selected. The selected tab has an orange border to reflect the type of markers being displayed. For example, when the Histogram tab is selected, the markers are histogram markers and are used to define the histogram window. Waveform Display Area The waveform display area shows the waveforms, and optionally, the results of your measurements. Several display options, including a grid, are available and can be configured using the graphical interface. Waveform Manipulation When using the graphical interface, two features are available that can simplify your work with waveforms: • Direct Manipulation—you can use the mouse to click and drag waveforms to new vertical positions, which changes the vertical offset, or to new horizontal positions, which changes the horizontal position or delay value. • Zoom—you can click and drag a rectangular area on the display, then click the Waveform Zoom menu item to zoom on that section of displayed waveforms. The oscilloscope does this in one of two ways. If acquisition is stopped, the magnification is done by the oscilloscope software. If acquisition is running, the oscilloscope automatically adjusts the vertical 54 Using the Oscilloscope scaling and offset and the horizontal scale and position to present the zoomed section of the waveforms. See “To zoom on a section of the waveform”. Avoid Overdriving Vertical Input Amplifiers When zooming on a waveform with the oscilloscope running, be careful to keep the signal within the screen vertically to avoid overdriving the vertical input amplifiers. Overdriving causes waveform distortion and erroneous measurement results. Ground Reference Indicators A small symbol is shown at the right side of the waveform display area for each waveform that is on, including channels, waveform memories, and functions. This symbol represents the ground reference point for each channel; it moves when you change the vertical offset. You can also drag this symbol up and down using the mouse or touch screen; doing so automatically changes the vertical offset for that waveform. Menu Control and Menus The display looks like figure 3-2 and figure 3-3, including a menu bar, measurement toolbar (if enabled), and graphical controls for vertical, horizontal, trigger, and acquisition. You can use the menu bar for most oscilloscope configuration functions. Context-sensitive menus, which pop up to provide a selection of commands within particular regions of the user interface, are available in the following regions: • Memory bar • Waveform display area • Measurement toolbar • Horizontal and acquisition controls You display a context-sensitive menu by clicking the right mouse button with the pointer in one of these regions. For more information on context-sensitive menus, see “To select a command from a context-sensitive menu” on page 3-63. Vertical Settings and Controls The top of the waveform display area includes the vertical settings and controls. All channels are shown with the corresponding vertical scaling settings in volts per division. Each has a checkbox allowing you to turn that channel on or off, and a set of controls allowing you to change the vertical scaling. Clicking directly on the vertical scaling value displays a pop-up numeric keypad allowing you to set a precise vertical scale. 55 Using the Oscilloscope Horizontal and Trigger Toolbar At the bottom of the waveform display area is the horizontal and trigger toolbar. This includes the run/stop controls, the horizontal controls, and the trigger controls. Run/Stop Control See figure 3-11. At the left side of the Horizontal and Trigger toolbar bar are six icons: • The leftmost is a blue-green octagon. Clicking this starts an acquisition. (Same as pressing the [Run] key on the front panel.) • The next control is a red octagon. Clicking this stops acquisition. (Same as pressing the [Stop] key on the front panel.) • The next control is a yellow octagon. Clicking this starts a single acquisition. (Same as pressing the [Single] key on the front panel.) • The next control is a small windshield wiper. Clicking this clears acquired waveform data from the display. (Same as pressing the [Clear Display] key on the front panel.) • The next control is a printer. Clicking prints the screen to the default printer. • The rightmost control is the waveform brightness control. Horizontal settings and controls The middle of the Horizontal and Trigger toolbar contains the horizontal settings and controls. Leftmost is a button, labeled with an “H.” Clicking this displays the horizontal setup dialog box. Next is the current horizontal scale. Clicking this displays a pop-up numeric keypad so you can set a particular horizontal scale. Or, you can click the two icons to the right of the horizontal scale setting to cycle through the preset speeds. The left icon shrinks the waveform, which decreases the horizontal scale and increases the time per division. The right icon stretches the waveform, which increases the horizontal scale and decreases the time per division. Next is the horizontal position (delay) setting. Clicking this displays a pop-up numeric keypad that lets you set a particular position. Or, you can use the three icons to the right. The left arrow moves the waveform to the left, the center “0” resets the delay to zero, and the right arrow moves the waveform to the right. Across the toolbar are three vertical arrows. These are the left, center, and right horizontal reference indicators. Clicking on one of these arrows moves the horizontal position to the respective horizontal reference position on the display—left, center, or right. Assuming the horizontal position is at zero: • Left means the information on the display is all post-trigger. • Center means the information to the left of center is pretrigger; to the right 56 Using the Oscilloscope is post-trigger. • Right means the information on the display is pretrigger. The horizontal position value represents the time relative to the trigger at the respective horizontal reference. When you change the horizontal scale, the waveforms expand and contract about this reference position. Trigger settings and controls The right side of the Horizontal and Trigger toolbar contains the trigger settings and controls. These will vary depending on the current trigger configuration, which can be set using the front panel and the graphical interface. Advanced trigger configuration items are available only through the graphical interface. You can click on the button labeled with a “T” to bring up the trigger setup dialog box. When the scope is set for edge trigger on a particular channel, the trigger level setting is shown. You can click it to display a pop-up numeric keypad that lets you set a particular trigger level. You can also click the up and down arrows to the right of the setting to increase or decrease the trigger level, respectively. You can also click the trigger reference indicator at the right side of the display and drag it up or down to change the trigger level. 57 Using the Oscilloscope To perform basic user interface operations • To move the pointer on the screen, move the mouse or touch the screen with the stylus and move it. • To click an item in the graphical interface, point at that item with the pointer, then press and release the left mouse button or touch screen. • To right-click an item in the graphical interface, point at that item with the mouse pointer, then press and release the right mouse button.

To turn a channel off, click the check box again to clear it. See figure 3-15. If you are not using a channel, you can turn it off. This simplifies the waveform display and also increases the display update rate. When you turn off a channel, the current vertical scaling factor and vertical scale buttons for that channel disappear. They re-appear when you turn the channel on. You can also turn a channel on or off by using the Channel Setup dialog box, or by using the front panel key for that channel. Figure 3-15 Turn a channel on by clicking the On check box until a check mark appears Turn a channel off by clicking the On check box until the box is cleared Turning a Channel On or Off 70 Using the Oscilloscope To adjust the vertical offset • Click and hold the left mouse button or touch screen stylus on the waveform you want to move, then drag the pointer up or down to move the waveform to the desired offset. Release when finished. or • Click and hold the left mouse button or touch screen stylus on the ground reference indicator for the waveform you want to move, then drag the pointer to move the waveform to the desired offset. Release when finished. or • Click the channel button in the vertical toolbar, then set the vertical offset using the spin box control in the Channel Setup dialog box. If you leave the mouse pointer on the waveform (without clicking), the pointer changes into crossed arrows as a visual indicator that you can drag the waveform when you click and hold. If you move the crossed arrow pointer up or down, the interface constrains the movement vertically and adjusts vertical offset only. If you initially move the crossed arrow pointer left or right, the interface constrains the movement horizontally and changes the horizontal position setting only. You can also adjust the vertical offset through the Channel Setup dialog box.

To shrink the waveform horizontally, click the smaller waveform button. See figure 3-20. The oscilloscope decreases or increases the number of seconds per division based on your selection. You can also adjust the horizontal scale by clicking the current setting. This displays a pop-up numeric keypad that allows you to set an exact value for the horizontal scale. Or, you can adjust the horizontal scale through the Horizontal Setup dialog box. See “To access the horizontal setup”. Figure 3-20 Click here to display the Horizontal Setup dialog box Click here to set the horizontal scale directly through a popup numeric keypad Adjusting Horizontal Scale 76 Click to shrink the waveform (more seconds per division) Click to stretch the waveform (fewer seconds per division) Using the Oscilloscope To adjust horizontal position The horizontal position is the time relative to the trigger at the highlighted horizontal reference point. • To zero the horizontal position, click the 0 button next to the position value at the bottom of the waveform display. This will position the trigger event at the highlighted horizontal reference point. • To move the waveform to the right or left, click the right or left arrow next to the position value at the bottom of the waveform display. Or, click and hold the mouse button on the desired waveform and drag the waveform to the right or left. Release the mouse button when the waveform is in the desired position. Clicking and dragging a waveform changes the horizontal position for all channels and functions on the display, but not that of waveform memories. You can also adjust the horizontal position through the Horizontal Setup dialog box. Figure 3-21 Click to set the horizontal position through a pop-up numeric keypad Move the waveform to the left Reset the horizontal position to zero Move the waveform to the right Adjusting Horizontal Position 77 Using the Oscilloscope To access the horizontal setup • Click the horizontal setup button at the bottom of the waveform display. or • Select Horizontal from the Setup menu. See figure 3-22. Using the Horizontal Setup menu, you can set scale, position, and the horizontal reference. You can also set up the delayed time base window, which uses software expansion to present a magnified view of an area of the waveform. See the Infiniium oscilloscope application’s online help (described in chapter 4) for details. Figure 3-22 Click this button... ...or select this menu item... ...to access the Horizontal Setup dialog box. Accessing the Horizontal Setup 78 Using the Oscilloscope To zoom on a section of the waveform 1 Click and hold the left mouse button or touch screen stylus in a blank space within the waveform display area, then drag the pointer to draw a rectangle around the areas of interest on the waveform(s) then release. 2 Click the Waveform Zoom menu item. How the zoom takes place depends on whether acquisition is running or stopped. If running, the oscilloscope adjusts vertical scale, vertical offset, horizontal scale, and horizontal position as necessary to best rescale the area you defined in step 1. If stopped, the oscilloscope does a software magnification of the waveform. In either case, a small dialog box appears in the corner of the screen, with an “Undo” button; by clicking this button, you will undo the zoom and return the oscilloscope to its previous settings. Avoid Overdriving the Vertical Input Amplifiers When the oscilloscope is running, the input waveform can overdrive the vertical input amplifiers if you expand the vertical excessively. The result is distortion of the waveform. Ensure that you select a region that will keep all of the waveform on the screen vertically. 79 Using the Oscilloscope Figure 3-23 Click and hold the mouse button, drag to create a selection rectangle, then click the Waveform Zoom menu item to zoom the display on the waveforms inside the rectangle. Zooming on a Section of the Waveform 80 Using the Oscilloscope To move the markers using the graphical interface 1 Turn on the markers. You can use the [Markers] key on the front panel, or select Markers from the Measure menu. 2 Click and hold the left mouse button or touch screen stylus while the mouse pointer is on one of the markers, then drag the marker to the position you want on the waveform, then release. Clicking and dragging a marker makes it easy to quickly move the marker to the desired waveform event. You can use the front-panel Measure Position knob for fine adjustment, or select the Markers command from the Measure menu and set the marker position precisely. See the online help for details. Figure 3-24 To move a marker, click the left mouse button or touch screen stylus with the pointer on the marker, drag the marker to the new position, then release Moving the Markers 81 Using the Oscilloscope To make a measurement on a waveform • Click and hold the mouse button or touch screen stylus on a measurement icon, then drag the icon to the waveform event you want to measure then release. or • Click a measurement icon, then specify which source you want to measure in the dialog box that is displayed. For measurements on waveform features, such as those that involve waveform edges, if you click the measurement icon and specify a source, the measurement defaults to using the feature closest to the horizontal reference point. When you make the measurement using drag-and-drop, the measurement uses the waveform feature closest to the point where you drop the icon. Only the most commonly used measurements are available on the toolbar. Others are available by selecting them from the Measure menu. A few specialized measurements are available only through the remote programming command set. See the Programmer’s Reference. When you drag and drop a measurement icon on a waveform, notice that the icon outline changes color to match the color of each waveform it touches. This lets you easily see which waveform will be measured when you release. Also, the measurement results are also displayed in color to make it easy to see which waveform source is being measured. For edge-sensitive measurements, when you drop the measurement icon on a waveform, a geometric icon appears in the waveform marker color. This icon shows exactly where the measurement is being made. The icon is also displayed next to the measurement results readout to associate the readout with the waveform and feature being measured. See figure 3-25. This feature helps you distinguish measurement results from each other when you make multiple measurements on the same waveform, but at different waveform features. For example, a series of rise time measurements on several different edges of the same waveform all have unique geometric icons to show each measurement’s location. 82 Using the Oscilloscope Figure 3-25 Channel numbers associate the measurement results with the channel waveform being measured. In some cases, geometric icons are also displayed to associate the measurement results with the location on the waveform being measured. Waveform Measurements 83 Using the Oscilloscope To access the trigger setup • Click the trigger setup button at the bottom of the waveform display. or • Select Trigger from the Setup menu. The trigger setup dialog box lets you select any of the different modes of triggering supported by the oscilloscope—Edge, Glitch, or Advanced, with choices under Advanced of Pattern, State, Delay by Time, Delay by Events, or Violation. You can set the parameters and conditions for each of those trigger modes. Figure 3-26 Click this button... ...or select this menu item... ...to access the Trigger Setup dialog box.

The online help is accessible from the menu bar and from dialog boxes. This chapter explains how to use the help to find the information you need to use the oscilloscope effectively. 90 Accessing the Online Help To access the online help • Select Contents from the Help menu. The Contents page for the oscilloscope online help is displayed. Figure 4-1 Select Contents from the Help menu to access the online help Help Menu 91 Accessing the Online Help Viewing the Online Help Window The online help provides several ways for you to find the information you need. The Contents topic, shown below, is the first method for finding information. It appears when you access the online help from the Help menu. Figure 4-2 Shows where the current topic is located in the table of contents Hides the view of the Contents, Index, Search, and Favorites tabs. Contents Topic Page 92 Prints this topic on the default printer Closes the online help window Accessing the Online Help . Viewing the Online Help Window The online help window always stays on top of the interface display, so you can refer to it while working with the oscilloscope. You can move the window around the screen or resize it to make it easier to use. The Index tab is the second method of finding information. You can type in a keyword and search the index for that keyword, or scroll through the list to find a topic. The Search tab is the third method of finding information. You can enter a keyword and if that word exists in the online help, a list of topics containing the keyword is shown. Because the search engine lists every topic that mentions the search word, you may find that certain searches generate many results. To make searching more efficient, first try searching only topic titles (you can enable this by checking the Search Titles Only box at the bottom of the Search pane). Then you might also use quotation marks so the help finds words only in a given order. For example, a search for sample rate will list every topic that contains either the word sample or the word rate. However, a search for “sample rate” returns only topics containing the phrase sample rate. Another useful feature is the Favorites tab. To access this tab press the arrow button next to the tabs selection area (see screen shot on previous page for this location) to display the Favorites tab. When you are on a topic you want to save to the Favorites tab, simply click on the Add button at the bottom of the pane. This enables you to build up your own mini-help system of topics you use frequently. Hyperlinks throughout the online help allow you to reach the information you need. Most hyperlinks will be in blue underlined text, but some hyperlinks also have buttons (many of the reference topics) or tabs (in setup guide topics). You can find out whether a particular item has a hyperlink by pointing to it; if it is a hyperlink, the pointer will change to a hand icon.

Index-99 Index 100 Safety Notices This apparatus has been designed and tested in accordance with IEC Publication 1010, Safety Requirements for Measuring Apparatus, and has been supplied in a safe condition. This is a Safety Class I instrument (provided with terminal for protective earthing). Before applying power, verify that the correct safety precautions are taken (see the following warnings). In addition, note the external markings on the instrument that are described under "Safety Symbols." Warnings • Before turning on the instrument, you must connect the protective earth terminal of the instrument to the protective conductor of the (mains) power cord. The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. You must not negate the protective action by using an extension cord (power cable) without a protective conductor (grounding). Grounding one conductor of a two-conductor outlet is not sufficient protection. • Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be used. Do not use repaired fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard. • If you energize this instrument by an auto transformer (for voltage reduction or mains isolation), the common terminal must be connected to the earth terminal of the power source. • Whenever it is likely that the ground protection is impaired, you must make the instrument inoperative and secure it against any unintended operation. • Service instructions are for trained service personnel. To avoid dangerous electric shock, do not perform any service unless qualified to do so. Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present. • Do not install substitute parts or perform any unauthorized modification to the instrument. • Capacitors inside the instrument may retain a charge even if the instrument is disconnected from its source of supply. • Do not operate the instrument in the presence of flammable gasses or fumes. Operation of any electrical instrument in such an environment constitutes a definite safety hazard. • Do not use the instrument in a manner not specified by the manufacturer. For technical assistance, please contact Agilent Technologies Technical Support. You can find the Technical Support phone number for your specific country on www.agilent.com. To clean the instrument If the instrument requires cleaning: (1) Remove power from the instrument. (2) Clean the external surfaces of the instrument with a soft cloth dampened with a mixture of mild detergent and water. (3) Make sure that the instrument is completely dry before reconnecting it to a power source. Agilent Technologies Inc. P.O.
