Since satellites are always in different locations, it can be challenging to repeat a test environment for CRPA testing. Historically, testing Controlled Reception Pattern Antenna (CRPA) systems in a ...

Measuring antenna gain patterns is a critical part of evaluating the performance characteristics of an antenna under test. A software-defined radio (SDR) is an economical and flexible radio system ...

The properties of an amplifier can be tested along the lines of the following sketch. Typically, this technique would be applied to an RF or microwave amplifier, but this technique's additional ...

This month, I’ll describe a nifty pocket-sized USB spectrum analyzer and show its pros and cons through some measurements on an ATSC signal, out after the mask filter and with some popular TV antennas ...

WEBVTT KELLY: ZACH WOBENSMITH DITCHED CABLE NEARLY EIGHT YEARS AGO. HE BOUGHT A TV ANTENNA AND NEVER LOOKED BACK. >> IF IT’S RAINING BADLY OUT. SOMETIMES I LOSE THE SIGNAL. MOST OF THE TIME IT COMES ...

This article addresses how best to quantify “which navigation system performs best” in a realistic testing scenario. The methodology focuses on land vehicles navigating in urban environments, but ...

In RF testing, an essential attribute of every RF signal generator is the maximum output power it can supply to a device under test (DUT) while maintaining spectral purity and level accuracy. The ...

An accumulation of factors within a test system can produce unacceptable waveform distortion, casting doubt on the validity of the test results. Present RF immunity standards do not stipulate waveform ...
