 Application Notes (App Notes) and Whitepapers (White Papers) are unquestionably an essential source of instruction for engineers and technicians. App notes and whitepapers on vendor sites are some of the fastest moving targets on the web. If click on a link and it is dead, please make an attempt to determine the new URL and notify me. Where possible, I have either downloaded and stored copies of PDF files*, or linked to the original webpages on the Archive.org service.

Application note from Linx Technologies. Understanding the Measurement Uncertainties of the Biconical / Log Hybrid Antenna
ets-lindgren.com/pdf/chen_bilog.pdf
Measurement uncertainty associated with the bicon/log hybrid antenna for radiated emissions and site validation tests relate to many factors, including height dependency, polarization and loading. Antenna Pattern Measurements:
(1) Concepts & Techniques
ce-mag.com/archive/02/Spring/fogelle1.html
(2) Theory & Equations
ce-mag.com/archive/02/Spring/fogelle2.html
The first article of this two-part series explores the basic concepts and techniques of antenna pattern measurement and evaluates the benefits and drawbacks of various measurement methods. The concepts relating to near-field and far-field pattern testing are discussed as well. The second article presents the theory and equations governing antenna properties and includes a complete description of a site calibration for pattern-measurement testing. By Dr. Michael D.

Combining specifications for gain, power, and voltage (and current, but not so often) that mix dB, dBm, dBW, watts, milliwatts, voltage, millivolts, etc., often requires converting back and forth between linear values and decibel values.

This tutorial should be useful both as an introduction to fiber amplifiers and for learning more details on them. We believe that even people already having a substantial experience with fiber amplifiers will find it helpful for deepening the understanding. The focus is on the underlying physics and the resulting technical consequences; we do not simply treat a fiber amplifier as a “black box”, but rather look inside.
