The touch screen user interface contains waveforms and plots, measurement readouts, and touch-based controls to access all oscilloscope functions.

Each area of the user interface has a specific function that helps manage information or controls.

1. The Waveform Record View is a graphical high-level view of the overall waveform record length, how much of the record is on the screen (shown in brackets), the location of key time events including the trigger event, and the current position of waveforms cursors.
   If you are displaying a Reference waveform that is shorter than the current acquisition record length, or you are changing the horizontal time scale while the oscilloscope acquisition is stopped, the brackets change position to show the part of the waveform record that is being viewed relative to the current acquisition total record length.
   
   
   If cursors are active on a waveform, the Waveform Record View shows the relative cursor positions as small vertical dashed lines.
   
   

   When in Zoom mode, the Waveform Record View is replaced with the Zoom Overview.

2. The Expansion Point icon on the waveform view shows the center point around which the waveform expands and compresses when changing horizontal settings.
3. The Trigger Position Indicator shows where the trigger event occurred in the waveform record. The trigger icon is displayed in the waveform slice that is the trigger source.
4. The Zoom icon switches zoom on and off. The front panel Multipurpose knobs also turn on zoom mode and change the position and horizontal size of the Zoom Box.
5. The Trigger Level Indicator icon shows the trigger level on the trigger source waveform. Some trigger types require two trigger levels.
6. Measurement and Search badges show measurement and search results.
7. The Results Bar Handle opens or closes the results bar, to maximize waveform screen viewing when needed. To reopen the results bar, either tap the handle icon or swipe left from the right side of the display.
8. The System badges show global instrument settings (Horizontal, Trigger, Run/Stop status, and Date/Time).
9. The Inactive Channel buttons add channel waveforms to the Waveform view and add an associated Channel badge to the Settings bar.

   The optional AFG button opens the AFG configuration menu to set and enable the AFG output. This button is only present if the AFG option is installed.

   The optional PG button opens the PG configuration menu to set and enable the PG output. This button is only present if the DPG option is installed.

   The optional D15-D0 button opens the digital channel configuration menu to set and enable the digital channel. This button is only present if the 2-MSO option is installed.

10. Double-tap a badge to open its associated configuration menu. If you add more Channel or Waveform badges than can fit in the waveform badge display area, tap the scroll buttons at each end of the waveform badge area to scroll and display hidden badges.
11. The Waveform Handles on each waveform identify the source of that waveform (Cx for channels, Mx for Math waveforms, Rx for Reference waveforms, Bx for bus waveforms). The waveform handles are at the zero-volt level of the waveform by default. The currently selected waveform handle is a solid color; unselected waveform handles are outlined.

    Double-tapping a waveform handle opens the configuration menu for that waveform.

    For digital channels, the waveform handle shows the channel number. Each individual digital signal is labelled D0–D15 and is with a different color.

    Double-tapping a digital waveform handle opens the digital channel configuration menu.

    Dragging a digital signal handle over another handle swaps those two signals on the waveform.

    

Badges are rectangular icons that show waveform, measurement, and instrument settings or readouts. Badges also provide fast access to configuration menus. The badge types are Channel, Waveform, Measurement, Search, and System.

Signal Clipping and Badges

WARNING:Clipping is caused by excessive or dangerous voltage at the probe tip, and/or a vertical scale setting that is not adequate to display the entire vertical range of the waveform. Excessive voltage at the probe tip can injure the operator and cause damage to the probe and/or instrument.

This instrument shows a warning triangle symbol and the words Clipping in a Channel badge when a vertical clipping condition exists. Any measurement badges associated with that channel also indicate a clipping condition by turning the measurement text red and listing the type of clipping (positive or negative).

To close the clipping message, change the vertical scale to show the entire waveform, disconnect the probe tip from the excessive voltage source, and check that you are probing the correct signal using the correct probe.

Clipping causes inaccurate amplitude-related measurement results. Clipping also causes inaccurate amplitude values in saved waveform files. If a math waveform is clipped, it will not affect amplitude measurements on that math waveform.

Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy. Use this procedure to adjust probe compensation for probes with a manual adjustment.

The following procedure checks the probe compensation.

1. Connect a supported probe to Channel 1.
2. Connect the probe tip and ground lead of the probe to the PROBE COMP terminals. Connect only one probe at a time to the PROBE COMP terminals.
   
   
3. Turn on the Channel 1 and turn off all other channels.
4. Tap File > Default Setup.
5. Push the Autoset button on the front-panel or tap File > Autoset from the menu bar. The screen should display a square wave with the levels between approximately 0 V - 2.5 V and 1 kHz.
   
   
6. Check the shape of the displayed waveform to determine if the probe needs adjusted. If the waveform has a square leading edge and a flat top and bottom, the probe does not need adjusted. If the waveform leading edge is rounded or has a spike, you need to adjust the probe compensation.
   
   
7. Use the probe adjustment tool provided with the probe to adjust the probe until the waveform has as flat a top and bottom as possible. Remove the adjustment tool before looking at the waveform. Repeat until waveform top and bottom are flat. See your probe manual for adjustment location and instructions.
8. Repeat these steps for each probe connected to each channel. You must run this procedure every time you move a probe from one channel to another.

Electrostatic discharge (ESD) can damage oscilloscope and some probe inputs. This topic discusses how to avoid this type of damage.

Electrostatic discharge (ESD) is a concern when handling any electronic equipment. The instrument is designed with robust ESD protection, however it is still possible that large discharges of static electricity directly into the signal input may damage the instrument. Use the following techniques to prevent electrostatic discharge from damaging the instrument.

• Discharge the static voltage from your body by wearing a grounded antistatic wrist strap while connecting and disconnecting cables, probes, and adapters. The instrument provides a ground connection to which to attach a wrist strap (on the Probe Comp ground connector).
• A cable that is left unconnected on a bench can develop a large static charge. Discharge the static voltage from all cables before connecting them to the instrument or device under test by momentarily grounding the center conductor of the cable, or by connecting a 50 Ω termination to one end, before attaching the cable to the instrument.
• Before you apply power, connect the instrument to an electrically-neutral reference point, such as earth ground. To do this, plug the three-pronged power cord into an outlet grounded to earth ground. Grounding the oscilloscope is necessary to ensure safety and to take accurate measurements.
• If you are working with static sensitive components, ground yourself. Static electricity that builds up on your body can damage static-sensitive components. Wear a wrist strap to safely send static charges on your body to earth ground.
• The oscilloscope must share the same ground as any circuits that you plan to test.

Inspection and Cleaning describes how to inspect for dirt and damage. It also describes how to clean the exterior and interior of the instrument. Inspection and cleaning are done as preventive maintenance. Preventive maintenance, when done regularly, may prevent instrument malfunction and enhance its reliability.

Preventive maintenance consists of visually inspecting and cleaning the instrument and using general care when operating it.

How often to perform maintenance depends on the severity of the environment in which the instrument is used. A proper time to perform preventive maintenance is just before instrument adjustment.

Use the following table to help isolate possible failures. The table lists problems and possible causes. The list is not exhaustive, but it may help you eliminate a problem that is quick to fix, such as a loose power cord.

For more information on troubleshooting, maintenance, and replacing parts on your instrument contact a Tektronix Service Center.
