The newest addition to RF Cafe's spreadsheet (Excel) based engineering
and science calculator -
Espresso Engineering Workbook™ (click to download)
is a functional Smith Chart that plots a series of user-defined impedance points. RF Cafe Espresso Engineering Workbook™ is
provided at no cost,
compliments of my generous sponsors.
The original calculators are included, but with a vastly expanded and improved
user interface. Error-trapped user input cells help prevent entry of invalid values.
An extensive use of Visual Basic for Applications (VBA*) functions now do most of the heavy lifting with calculations,
and facilitates a wide user-selectable choice of units for voltage, frequency, speed,
temperature, power, wavelength, weight, etc. In fact, a full page of units conversion
calculators is included. A particularly handy feature is the ability to specify
the the number of significant digits to display. Drop-down menus are provided for
convenience.
I been adding new calculators
on a regular basis.
For the time being, the VBA code is password protected. At some
point, a version might be made available with full access, but during the development
stage, I prefer to not expose all my hard work for easy poaching.
A lot of effort has been expended validating calculations, including references
from books, magazines, and other software. As always, you are advised to check results
against other sources if something seems off. If you do find an error, please report
it to me ASAP so it can be corrected with the next release.
The file is in an xlsx format compatible back to Excel 2007 - and it
may work for even earlier versions.
* Note: Because
VBA code is used, you must allow Excel security to enable macros.
This edition includes the following calculators:
