    Australian Patents Act 1990 - Regulation 3.2 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title Method and apparatus for testing and displaying test results The following statement is a full description of this invention, including the best method of performing it known to me/us: P/00/Oll 5102 1a Background of the Invention This disclosure relates to test and measurement, 5 and more particularly to a method and apparatus for performing testing and displaying test results from testing. When making test measurements on computer networks, for example, in setup and testing of 10 installations with large numbers of network cables, testing must be performed to ensure that the various network cabling is fully functional, whether copper wire based network cable, fiber optic network cable, or wireless networks. Large installations can comprise 15 hundreds or more cables needing testing. Accordingly, tracking the testing process becomes important, to allow efficient testing and use of the technician's time. A test instrument may include the ability to save 20 test results, for documentation and proving of the network installation. However, it has been noted that there can be a psychological barrier to saving results from failed tests, as technicians would prefer to have all their test results show passing. So, a technician 25 may decline to save negative results, preferring instead to come back later to test again, perhaps after making some corrective adjustment to the network cables. Such action can reduce efficiency in the test operation, and can also result in missing items that 30 might need to be corrected. The operation of network test instruments can require a level of technical expertise, with multiple options and test suites being available, such that technicians with lesser experience may be confused as 35 to what test or measurement to perform in a particular AM 18158693.1 2 situation. It is desirable to have technicians with less experience performing the bulk of testing, saving the more experienced technicians' time for working on particularly difficult issues or for correcting network 5 cabling that does not pass initial testing. FIGs. 2-7 illustrate prior art display screens, wherein FIGs. 2 and 3 represent starting screens where testing is initiated. FIGs. 4 and 5 represent 2 different types of summary of test information screens, 10 FIG. 2 representing a failed test and FIG. 3 representing a passed test. FIGs. 6 and 7 represent screens for viewing test results. In FIG. 8, a prior art representation of a tested cable is shown. While individual cable segments are 15 shown, viewing test results from any particular individual cable segment requires moving to a different display screen, scrolling through results until the particular segment of interest is located. 20 Summary of the Invention In accordance with the invention, an improved display method and device is provided for operating a network test instrument and for displaying test results from network testing. 25 Accordingly, it is an object of the present disclosure to provide an improved network test instrument. It is a further object of the present disclosure to provide an improved network test instrument that 30 provides easy tracking of project status. It is yet another object of the present disclosure to provide an improved network test instrument and method that provides a measure of the project completion. 35 It is yet another object of the present disclosure AM 18158693.1 3 to provide an improved network test instrument and method that provides a suggested next operational step to be performed. It is yet another object of the present disclosure 5 to provide an improved network test instrument and method that provides an option to mark a test item to be re-tested later. The subject matter of the present display method and apparatus is particularly pointed out and 10 distinctly claimed in the concluding portion of this specification. However, both the organization and method of operation, together with further advantages and objects thereof, may best be understood by reference to the following description taken in 15 connection with accompanying drawings wherein like reference characters refer to like elements. Brief Description of the Drawings FIG. 1 is a block diagram of a test instrument 20 that embodies the method and apparatus; FIGs. 2-8 are example of prior art displays provided by test instruments; FIG. 9 is a home screen view in accordance with the disclosure; 25 FIG. 10 is a project page display; FIG. 11 is a 'change project' page display; FIG. 12 is a 'manage project' page display; FIG. 13 is a 'test setup' page display; FIG. 14 is a 'test type' page display; 30 FIG. 15 and 16 are tools setting page displays; FIG. 17 is a version information display page; FIG. 18 is an example display resulting from selection of the visual fault locator test option; FIGs. 19-25 illustrate screens displayed during 35 testing; AM 18158693.1 4 FIGs. 26-29 illustrate viewing results screens; FIG. 30 is a change ID screen; and FIG. 31 is view of a particular display for entering new project information. 5 Detailed Description The system according to a preferred embodiment of the present disclosure comprises a method and apparatus for testing networks. 10 The method and apparatus provides an easy to use test instrument which provides suggested next operational step information to a user, provides the ability to display a percentage of a project that has been completed, and provides the ability to save test 15 results to a 'fix later' list or to immediately test again, eliminating a user's predisposition against saving failed results, but still providing tracking of failure tests. A percentage of project completed amount is displayed to give easy review of the overall 20 amount of a project that has been completed, so a technician or manager immediately can see how much of a project is complete and how much work is left to do. The overall pass and fail rate is displayed, suitably in the form of providing the number of passed, failed 25 or marginally passed test items. When reviewing results, any failed test results are moved to the top of the list, which thereby provides a 'punch list' of results that need to be addressed, eliminating the need to search through an entire list of test results to 30 sort out the failed items from the passed items. A suggested next operational step option is provided at many points during operation of the instrument, for example in the form of a highlighted next option choice, to provide the technician using the device with 35 a 'what should I do next' operational assistance. AM 18158693.1 5 FIG. 9 illustrates a home screen in accordance with the disclosure, wherein a screen 10, which is suitably a touch screen project name 12 may be displayed, along with an operator's name 14, A 5 percentage tested value is displayed at 16, representing, for example, the percentage of network cables in a particular project that have been tested and/or passed testing. In the example, a value of failed test items is 10 shown at 18 (1X), suitably displayed in a color such as red, for example, while optionally, a value 20 shows 10 items that marginally passed the testing, suitably displayed in another color, such as orange. Value 22 shows in the illustration that 13 items have passed 15 testing so far, suitably displayed in yet another color, such as green. An indicator at 24 denotes which end of the cable the results are pertaining to, while displayed values at 26 give various indications of the type of testing being performed. In the illustration, 20 an optical test instrument is shown, with a singlemode auto OTDR testing, ANSI/TIA-568-C standards testing, with a CommScope TeraSPEED type fiber being tested.

A status display 90 (ACTIVE) is provided 20 together with a visual representation of the test instrument. Pulse button 92 is provided to allow the technician to activate a pulsed visual beam. FIGs. 19-25 illustrate screens displayed during testing. 25 FIG. 19 is a view of an alternative 'home' screen to that of FIG. 9, in a preferred embodiment, wherein a particular selected testing project named TESTING 123 is illustrated. In this embodiment, in place of having project icon 32 of FIG. 9, the project selection 30 function may be chosen by selecting the screen in an area 93 where the current project is displayed, which will operate to transfer to a project selection screen (for example, the screen of FIG. 10). In this view, 15 cables have passed testing while 13 have failed. The 35 testing being performed is Auto OTDR on an OM3 AM 18158693.1 9 Multimode 50 micron cable, testing to ANSI/TIA-568-C standards. Next ID is blank, while the currently being tested cable ID is AA123, End 2 is indicated to be DESK. An operator's name is shown (Sena). Tools and 5 Results icons are available for selection, while the next suggested operation is "TEST". FIG. 20 shows a testing progress screen, wherein the test type is displayed at 94 (Auto OTDR of End 2 of the cable), a graphic display 96 in the form of 12 10 small circles arranged regularly in the form of a circle, wherein the circles are successively highlighted or changed color to illustrate the passage of time during the testing activity, a time remaining field 98 provides an indication of the remaining time 15 in the particular test underway, and a Port Connection Quality field 100 shows both graphically in the form of a horizontal bar having multiple color region 103, 105 and 107 and an arrow 102 that moves along the length of the horizontal bar, the leftmost position representing 20 the lowest quality performance and the rightmost position representing the highest quality performance. The word POOR 104 is displayed as the particular illustrated test result is of poor quality at this point in the test. The colors 103, 105 and 107 25 represent poor, marginal and good test results, and may comprise red, yellow and green, for example. A cancel button 106 is provided to allow the technician to cancel the test before it has completed. FIG. 21 illustrates an example display in the case 30 where a FAIL condition has been detected. The identifier of the particular cable being tested is displayed at 108, as well as the word FAIL at 110, suitably set in a colored bar 109 of a color representing failure, such as red. A representative 35 map 112 of the cable under test is shown, a fiber optic AM 18158693.1 10 cable in the illustrated example, with length values and an indicator 114 of the location of the failure event, in the form of a box with an X. The test instrument itself is represented at 116. Next to the 5 failure indicator box 114 is an annunciator box 118 that denotes a loss event is detected at 100.56 meters from the test instrument, the loss value is displayed (1.02db) as well as a reflection value (-20dB). Also shown is the measured value of fiber length (1000.00 10 meters), the overall lost (1.42 dB) and the test limit (Fibre Channel 1200-M5E-SN-I). Additional display options other than the fiber map shown are, table 120 or trace 122, which display the test results in other formats, shown in FIGs. 23 and 24, selected by touching 15 the box containing the words TABLE or TRACE (as is selected the FIBER MAP option displayed in FIG. 21). In the view of FIG. 21, distance values are displayed, representing the distance from the test instrument to the various located events, which in the 20 illustrated display are connectors along the cable under test. In the particular display connectors are located at .5, 25, 100, 300, 500 and 1000 meters from the test instrument. Further provided at the bottom of the screen are a 25 'FIX LATER' button 124, which operates to save the cable identification and test information into a list of items to be addressed later. This function provides an easy way for the technician to defer having to investigate or fix the particular failing test item. 30 TEST AGAIN button 126 is provided as the suggested next step, again in a suitable color, such as yellow in a particular embodiment. FIG. 22 illustrates an alternative display to that of FIG. 21, wherein the particular display of FIG. 22 35 is a preferred embodiment screen display option AM 1sS8693.1 11 compared for example to the format of FIG. 21. The Fiber Map view of FIG. 21 is called an 'EventMap' view in FIG. 22, this particular view being that of a passed test result, where a loss value of 0.18dB has been 5 detected at 18.20 meters from the test instrument, this particular test value on a cable identified as cable 006. A box 128 of a different color than other portions of the representation of the cable is provided to graphically illustrate where the event being 10 displayed is located on the cable. In the views of FIGs. 21 and 22, the vertical lines provide representations of the cable under test, while the boxes 119, 119', etc. represent cable connectors. Circle 121 represents a loss event that 15 was detected during the test. The displayed measurement values shown at 118, 1181 may be displayed by selecting the individual event or connector, by touching the connector/event on the display, whereupon the test details related to that particular connector 20 or event are displayed as shown in FIGs. 21 and 22. In the case where the cable under test is sufficiently long such that a representation of the entire cable is not displayable on the screen, scrolling buttons are provided to enable scrolling of the display back and 25 forth along the length of the cable, so that all the events and connectors may be observed. In the view of FIG. 22, distance values are displayed, representing the distance from a particular event or connector to the next event/connector. In the 30 particular display, a first event is 18.20 meters from the test instrument, with subsequent connectors at 86.68 meters, 52.74 meters thereafter, 1.02 meters thereafter, 52.58 meters thereafter and 102.47 meters thereafter. 35 FIG. 23 illustrates a table view of test data for AM 18158693.1 12 cable 006 of FIG. 22, wherein various values are displayed of events, such as cable end (at 313.69 meters), reflections (at 211.22, 157.62, 104.88 meters), etc. The displayed tabular data is shown at 5 850 nm, with buttons 130, 132, provided to allow movement to test data at other frequencies. An OVERALL button 134 is provided to display an overall test result value for the cable, rather than individual event values as shown in FIG. 23. The word PASS 138 10 appears in a colored bar 136 (suitably green, for example). FIG. 24 shows an example of a TRACE display of test results on cable 006, wherein a graphic display 140 providing trace views is provided, along with 15 events movement buttons 141, 142 which allow movement between events that were located during the testing. A cursor 144 is shown placed at 109.9 meters (shown by box 146) with upper highlight 148 on the cursor, and a second cursor 150 is positioned to the right of the 20 first cursor.

FIG. 25 is a view of a display screen in Fiber 25 Inspector mode, wherein a microscope view of the end of the fiber is displayed in region 154. A 'SCALE OFF' button 156 is provided to turn the scale 158 alternately off or on, as well as a GRADE button 160, a focus button 162 and a next arrow 164. In this screen, 30 SAVE button 166 is the suggested next step operation button, again presented in a 'suggestion color' such as yellow. FIGs. 26-30 illustrate viewing results screens and a change ID screen. 35 FIG. 26 shows a view all results screen, wherein AM 18158693.1 13 an active project region 168 displays a currently active project, and other projects region 170 shows other projects that are stored in the device. A percentage of project uploaded value is displayed, to 5 indicate how much of each project has been uploaded from the instrument to another device or storage. An upload button 172 is employed to upload a selected project, while a delete button 174 allows a project to be deleted (for example after uploading the project 10 data). A done button 176, which is the suggested next procedure button in this view, is provided. FIG. 27 illustrates a manage results screen wherein results of a testing project may be displayed, sorted by date or identification by selection of 15 ID/DATE field 178. A select all retests check box 180 is available to indicate all items in the list should be retested, or individual check boxes 182, 182', etc. may be selected to select a subset of the items for retesting. Move, rename and delete functions are also 20 available, delete being the suggested next step for this particular state of operation. FIG. 28 shows a different results set from a different test named Main Street Hospital, which shows 4 failed tests, 1 marginal and 283 passed tests. The 25 four failed tests are shown at the top of the screen with an indication '4 Retests Needed', followed by the 1 Marginal Pass test result, followed further by the 283 passed test results, which may be scrolled up and down to move into view on the screen as desired. A 30 view all, upload or manage function button may be selected at the bottom of the screen for further operation. No suggested next step option is provided in this particular screen. FIG. 29 shows yet another results display for a 35 test set named Janok, showing 11 passed tests and 2 AM 18158693.1 14 retests needed. The method and apparatus presents a convenient way to manage retesting, by presenting the items needed retesting in a punch list, allowing the technician to easily determine which items need to be 5 retested and then to accomplish the retesting. FIG. 30 illustrates a display screen for a change ID function, wherein the identifier assigned to any particular cable can be changed, by selection of CHANGE CABLE IDs button 184, which will then present a 10 keyboard display to allow editing of the name of a particular cable identifier. "DONE" is the suggested next step option presented in this particular view. Referring now to FIG. 1, a block diagram of a test instrument, in this particular embodiment, an optical 15 networking test instrument 200, the instrument connects to a network under test 202, an optical network in a particular embodiment, via network interface(s) 204. The instrument includes processor(s) 206, memory such as RAM/ROM 208, persistent storage 210, I/O 212 which 20 attaches the device to a network or other external devices (storage, other computer, etc.), display 214, user input devices 216 (such as, for example, keyboard, mouse or other pointing devices, touch screen, etc.), power supply 218 which may include battery or AC power 25 supplies. Microscope 220 provides the inspection function to view the end of the fiber in the FiberInspect mode. The processor(s) operate the instrument to provide test and measurement function for the network. 30 In operation, the network test instrument is attached to the network, and observes transmissions on the network and provides stimulus and response measurement to collect information and statistics and effect testing and measurement. 35 In accordance with the method and apparatus AM 18258693.1 15 disclosed herein, an improved test instrument and method are provided, for testing of wired, fiber optic or wireless networks, for example, wherein in a test summary screen, FIX LATER or TEST AGAIN options are 5 provided as possible next steps for the user of the instrument to take. This terminology eliminates the fear of saving a 'failed' result and having to come back to fix it. This eliminates some of the psychological predisposition against saving failed 10 results, while allowing tracking of failure tests, allowing the user's immediate concerns to be addressed to either fix later, or immediately test again. Further, the provision of a percentage of project completed display on the home screen for example, 15 provides an improvement whereby the amount of a project completed may be easily gauged, for tracking of results. The user instantly knows how much more work is left to do on a particular project. Also, display is provided of the number of passed, failed or 20 marginally passed test items, to provide an instant view of overall results. Also, on a results display screen, any failed results are moved to the top of the displayed list, providing a 'punch list' of results that need to be addressed. This type of organization 25 eliminates the need for a technician to hunt through a set of results to find the failed items needing re testing. The provision of a suggested next operational step, suitably in the form of a particular colored or highlighted function button (such as yellow with an 30 arrow appearance to the button at a common screen location, such as the lower right), provides the user with assistance in the form of 'what should I do next' suggestions. Graphical display of the cable under test provides an easy way to view individual results of 35 events or connectors on the cable, by touch selection AM 18158693.1 16 of a graphical representation of cable elements or events, and resulting display of the particular test results related to the selected cable element or event. While a preferred embodiment of the present S invention has been shown and described, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from the invention in its broader aspects. The appended claims are therefore intended to cover all such changes 10 and modifications as fall within the true spirit and scope of the invention. Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgement 20 or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates. 25 30 35
