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 ...

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 ...

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 ...

PHOENIX—Single Frequency Network testing of ATSC 3.0 here has proven the efficacy of this multi-site TV transmission scheme in boosting signal level and service margin, significantly improving ...

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 ...

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 ...

I recently had a chance to try out a really cool-looking — at least in the opinion of some — antenna for my truck. The brand itself doesn’t matter much as these are all similar in design: flexible ...
