    RBMware Sweep Analysis Option

    The Sweep Analysis option in RBMware v4.70 (or later) is for the purpose of displaying and manipulating the sine curve data uploaded from the UltraSpec Pro Align Plus and Vertical Align Plus DLP’s and the 2120 Pro Align Plus DLP. For the moment while research on how best to use this new feature is in progress, the Sweep Analysis option is intended for internal use and those customers that specifically request access to it.

Accessing the Sweep Analysis option

    When RBMware v4.70 (or later) is initially installed this option is disabled. To enabled it, edit the csi.ini file for the user the option is to be enabled and add the following line under the UltraAlg section:

    dosweepanalysis=1

Note

    If for example, the option is to be enabled for User#1, the csi.ini file for this user would be located

    under the RBMsuite\Users\User#1 directory.

When finished the UltraAlg section should look similar to the following:

    [UltraAlg]

    dosweepanalysis=1

    ready=1

    RIGHT=930

    BOTTOM=721

    LEFT=111

    TOP=130

    MAXIMIZED=0

    After the required line has been added and saved to the csi.ini file, the Sweep Analysis option can be accessed from the UltraAlign main menu (shown below under the Alignment Reports option).

    Note

    If RBMware is reinstalled such that it overwrites the previous RBMware installation, the Sweep

    Analysis option will still be enabled.

Displaying Sine Curves

    To select and display a sine curve, select the Sweep Analysis option. The following screen is displayed.

Note

    Throughout this document Example.rbm will be used to explain the Sweep Analysis option. The last

    four jobs stored under the Unassigned (Global) Area contain sine curve data (reading) sets required to

    use the Sweep Analysis option. The HorzFulSwp and VerFullSWP job data was acquired from a full

    sweep while the HorzParSwp and VerParSWP job data was acquired from a partial sweep.

    After selecting the desired job (in this case HorzFulSwp) the available reading sets (if more then one) are displayed as shown in the following screen. Up to 20 reading sets can be stored on a job.

    Preferences - Allows you to specify the following options:

    ; Plots Printed Per Page: The number of plots printed per page.

    ; Vertical Size of Plot (%): The percent of the page each plot will use.

    Note

    When wanting to print more then one plot per page, you will need to reduce the vertical size of the

    plot to get them on the same page. At 100%, one plot will take up the entire page when printed.

    When printing two plots per page (for example) try reducing the vertical size of the plot to 50% or

    less.

    Select the desired reading set to view its sine curve plot. The sine curve plot (in this case Reading Set 2), as it is stored in the database, will be displayed as shown in the following screen.

Sine Curve Plot Control Options

    This section describes the controls used to manipulate and navigate the readings displayed in the sine curve plot. These controls include menu bar (shown above), toolbar (shown above), function bar (shown above), keyboard key functions, and mouse functions. For a description of the basic functions available for the sine curve plot see “ Universal Plot Control Keys and Tools” on page 5-3 under UltraAlg help. For a description

    of the new functions not described under UltraAlg help, see below.

Graphics Function Bar:

    Text Brings up a dialog box that allows you to insert a text label (32 characters

    maximum) in the left-hand side just below the plot (as shown below).

    11/26/2010 Page 5 of 21

    If "Store Modified Label" on the Sweep Analysis Display Options menu has been

    selected (refer to the Sweep Analysis Display & Plot Setup Options section for

    more information), this text will be saved in the database along with the plot (as

    shown below).

    11/26/2010 Page 6 of 21

R Drag Action (Right Drag Action) Used to insert, delete, or toggle a section of

    readings on the sine curve plot selected with the right mouse button. The toggle option will insert a reading(s) if deleted and delete a reading(s) if inserted. This option can also be set from the Sweep Analysis Display Options menu. Refer to the Mouse Functions section and the Sweep Analysis Display & Plot Setup Options section for more information on this function.

    Reset Restores the plot back to its original saved (as stored in the database) condition, if modified. Also, clears cursor, label values, set mark, and text label (if not saved with the plot) from the plot.

    11/26/2010 Page 7 of 21

    Graphics Save Saves the plot to a graphics file. The Graphic Capture setup is

    located on the Edit menu at the top of the screen. This option is not new to

    UltraAlg, but is described under Alt-S option under UltraAlg help.

    Keyboard Key Functions:

    As a convenience to users of previous MasterTrend versions (and those that prefer using a keyboard instead

    of a mouse), the following keyboard keys can still be used to perform the functions described.

    The Left/Right Arrow keys activate and control the horizontal movement of the

    cursor through the plot (one reading at a time). Information related to the angular,

    vertical, and estimated vertical positions of the cursor are displayed in the lower

    right-hand side just below the plot (refer to the Cursor Variables section for more

    information on these variables).

    The Home key activates and returns the cursor to the beginning of the Left Head’s sine curve plot (extreme left-hand side of the plot).

The End key activates and places the cursor at the end of the Right Head’s sine curve plot

    (extreme right-hand side of the plot).

    The Esc (Escape) key allows you to terminate plotting and return to the Sweep Analysis screen without accepting any modifications made to the plot (refer to the Displaying Sine Curves section for more information), if any were made. From the Sweep Analysis screen you can select another reading set.

    The Enter keys allows you to exit plotting and return to the Sweep Analysis screen after deciding whether or not to accept any modifications made to the plot (refer to the Displaying Sine Curves section for more information), if any were made. From the Sweep Analysis screen you can select another reading set.

    The Delete key will clear cursor, label values, set mark, and text label (if not saved with the plot) from the plot.

    The Insert key will insert a reading if deleted or delete a reading if inserted. This function is performed on the reading selected by the cursor; therefore, the cursor must be active for this function to be performed. After the operation is performed an updated sine curve plot based on the inserted or deleted reading is displayed.

    Mouse Functions:

    The left mouse button can be used to define the cursor position on a reading. To select a reading in the sine curve plot with the cursor, position the mouse pointer on the reading that you want the cursor to be display on, then press the left mouse button. Information related to the angular, vertical, and estimated vertical positions for the reading which the cursor is located are displayed in the lower right-hand side just below the plot (refer to the Cursor Variables section for more information of these variables).

11/26/2010 Page 8 of 21

    The right mouse button can be used to select a section of readings in the sine curve plot for

    insertion, deletion, or both. Position the mouse pointer close to the section that you want to the

    insert/delete operation to be performed, press the right mouse button, and then drag the

    selection box until it surrounds the section of the plot you want to insert/delete operation to be

    performed. When you have the selection box positioned, release the right mouse button.

    Note

    To abort the operation after you have pressed the right mouse button, drag the cursor

    below the plot and release the button.

    When the right mouse button is released, the program will perform the specified operation and

    display an updated sine curve plot based on the outlined section that was modified. The

    operation performed is based on what is selected under the Right Drag Action option (refer to

    the Graphics Function Bar section for more information) or the Sweep Analysis Display

    Options menu (refer to the Sweep Analysis Display & Plot Setup Options section for more

    information). To return to the plot back to its original saved (as stored in the database)

    condition, select the Reset option.

Sine Curve Plot Variables and Information

    This section describes the variables and information displayed in the sine curve plot.

Sine Curve Plot Variables:

    The following variables are displayed for each sine curve (as shown in the sine curve plot above).

    Phase Indicates (in degrees) where the plus zero transition is positioned (see below). The analyzer displays this same variable.

    Offset Indicates (in mils) the centerline of the laser travel on the target in the radial direction. The initial position of the laser on the target effects this variable. The analyzer displays this same variable.

    Ampl (Amplitude) The maximum displacement (in mils) of the sine curve (see below) from the offset line. The analyzer displays this same variable.

    Sine Fit An indication or confidence factor (shown as a percentage) used to determine the quality of the sine curve data. The analyzer displays this same variable.

    Num Pnt Adj An indication (shown as a percentage) based on the number of inserted (also referred to as active) readings. A higher number indicates too few inserted (active) readings with which an accurate sine curve can be generated. For example, 36 readings will generate a more accurate sine curve than 3 readings.

    Space Adj An indication (shown as a percentage) based on the spacing (mean distribution) between the inserted (active) readings. A higher number indicates a clumping of reading as opposed to a desired even distribution of readings.

    Num Pnts (Number of Points) The number of inserted (active) readings displayed in the sine curve. The number of points (also referred to as readings) can vary between 3 and 180 depending on the readings stored for the sine curve and the plot display setup.

    Cursor Variables:

    When the plot cursor is active, the following variables are displayed in the bottom right-hand of the plot (as shown below):

Angl (Angle) The selected reading’s angular position (in degrees). When a reading has been deleted an

    asterisk mark (*) is displayed next to the angle position (as shown below).

Vert (Vertical) The selected reading’s actual vertical position (in mils).

Est (Estimate) The selected reading’s estimated or calculated vertical position (in mils).

    The following screen has the plot type set to “Side by Side” (refer to the Sweep Analysis Display & Plot Setup Options section for more information).

When the plot type set to “Overlayed” (as shown below) or “Overlayed, No Offset”, a box is displayed

    around the information to the right of the plot for which the cursor is active. Refer to the Sweep Analysis Display & Plot Setup Options section for more information on setting the plot type to “Overlayed” and

    “Overlayed, No Offset”.
