I.        Getting Started

 
 

 

 


Verify that you are using the latest software available.  Upon calling up the viewer, click on the upgrade button located on the right of the pull-down menu and notice that a new pop-up window appears.  The version you are running is listed here along with a link to an ERI website where updates may be downloaded at no charge.  Click on the link to start a session of your web browser, and verify that you have the latest software version, as it is listed on the website http://www.eriinc.com/download1.htm.

 

II.       Using the Software

 
 

 

 

 


A.     File

1.      Load (the file) – To load a file, click on the File menu button and pull down to the Load option.  This will open a window allowing you to select the correct directory and choose the file to load.  The file will have an extension of .fig

 

2.      Save (the file)

a)     Text – This feature allows the numeric values of the graphical pattern to be output via simple text files.  The options available include horizontal or vertical values.

(1)   Horizontal – Numerically outputs the horizontal polarization field values as represented on the fig plot.  The file is a simple text file.  The results are represented in one degree increments of azimuth, starting at zero.
(2)   Vertical – Numerically outputs the vertical polarization field values as represented on the fig plot.  The file is a simple text file.  The results are represented in one degree increments of azimuth, starting at zero.

b)     Comstudy – This feature exports the overall values of the pattern RMS and Power Factor into a simple text file. 

(1)   Horizontal – Numerically outputs the specific horizontal RMS values at a given azimuth.  The output is a simple text file that begins starting at zero degrees then increasing in five degrees increments. 
(2)   Vertical – Numerically outputs the specific vertical RMS values at a given azimuth.  The output is a simple text file that begins starting at zero degrees then increasing in five degrees increments. 

 

3.      List (detailed results) – This feature creates a pop-up window displaying the values for the H-pat, V-pat, the associated db levels, and the power factor at each degree of rotation.   This graphical chart is color coordinated to match the Relative Field Pattern plot as seen in the main viewer window.   To access the power factor information for a specific point on the graph, place the mouse cursor on top of the desired “pat” value in the chart.

 

4.      View  – Refresh the screen while the pattern viewer on top.

 

5.      Print  – This feature allows the pattern data to be printed on your windows default printer.

 

6.      End – The program shuts down.

 

B.    Rotate – This feature opens a window allowing the input of an azimuth correction for the pattern seen in the main viewer window.  User must input a value from –359 to 359.   A negative value will rotate the pattern counter-clockwise, while a positive value rotates the pattern clockwise.

 

C.    Upgrade – This feature opens a window allowing the input of an azimuth correction for the pattern seen in the main viewer window.  User must input a value from –359 to 359.   A negative value will rotate the pattern counter-clockwise, while a positive value rotates the pattern clockwise.   Multiple consecutive moves are allowed.

 

III.      Notes

Alt + U = A pop-up window providing current software version and a link to upgrade

 

Ctrl + E = End program

Ctrl + H = Save the Horizontal values of the pattern in a simple text file format

Ctrl + L = Load Pattern file into viewer

Ctrl + P = Print the pattern

Ctrl + S = List all values in a pop-up window
