Wireless System Designer™
has all calculations on a single worksheet to make inserting and deleting component columns
simple - well, relatively simple. There are certain rules that need to be followed in
order to assure that all the formulas retain their proper references to other cells' values.
Wireless System Designer™ does not require any special steps that are not
common to Excel or other spreadsheets, but it is probably safe to say that most users
are either not familiar at all with the procedure, or do not use it often enough to be
confident without a reminder. I have outlined the necessary steps and done screen captures
* Rather than Deleting columns, I
recommend using Excel's "Hide" feature to prevent system component columns from appearing
on the screen or on the charts. A hidden cell's contents is still included in the cascade
calculations, it just is not shown on the screen.
Note: When columns are inserted or deleted, Excel conveniently adds
or deletes, respectively, data sets to the Line Charts. Scatter Charts do not
automatically add or delete data sets. Fortunately, the only Scatter Chart is the Frequency
Response graph that plots signal power levels inclusive of filter rejection. Therefore,
it will be necessary to separately modify the Frequency Response chart after adding or
NOTICE: I highly recommend that you make a backup of the
original version of your workbook before adding or deleting columns just in case something
goes awry. Excel only allows you to Undo edits up through the last time you save the file,
so if you make changes and save the file, then make more changes and discover that your
mistake occurred prior to that last save, you're out of luck. That's an Excel thing, not
a Wireless System Designer thing.

Being a firm believer in the adage that says a picture is worth a thousand words, these
annotated screen shots outline the complete series of steps required to assure successful
insertion of component columns. Stray at your own risk. Don't forget to make a backup
Before detailing the procedure for deleting columns, I would like to suggest that rather
than deleting columns that you instead set all the input parameters for the column(s)
to null values that do not affect the overall cascade calculation results, and then simply
Hide the column(s). Hiding a column causes it to disappear from the spreadsheet and any
values from a hidden column do not appear on the charts. You can Unhide column(s) later
if the space is needed. I provide a screen shot of the suggested null values to use.
However, if you still prefer to deleted unused columns, the following procedure gets
the job done.
