RF Mentor Academy

RF Mentor Academy is available as a source of online training on RF and Wireless topics for users of RF Mentor. The site features some free webinars and study guides, but also online courses from Besser Associates. We will be using the site to offer some products in slightly different formats than what we offer on our main corporate site.

Calculators Maintenance Update

I've done some updates to a couple of calculators on the site. The Animated Reflectometer HTML5 version had a bug where the animation would be drawn with the wrong sign for values entered into the load impedance (ZL) field. The displayed numerical results were correct, but the animation would demonstrate an open circuit condition if you entered zero impedance for the load, instead of displaying a shorted condition. This has been fixed now.

Here Come the Calculators!

I've been experimenting with JavaScript a bit lately and came up with a bit of code to make creating calculators for RF Mentor users quite a bit easier. Based on the fact that most of the online calculators share some common functionality as far as the website is concerned, I've created some base "formula" and "variable" objects to handle the creation of the input form and display tasks. As a result, creating a new calculator is a much simpler matter of defining the variables and writing a function for the calculation of the output value.
