The vector network analyzer (VNA) is an advanced member of the oscilloscope family of electronic instruments. The DUT may be as simple as a single resistor or conductor. The VNA can also operate as a time domain reflectometer, measuring the distance to and nature of a fault, impedance anomaly, complete break or short in a […]

Basics of measuring fuel cells
A fuel cell converts oxygen or another oxidizing agent and hydrogen or some other fuel into electricity and heat. A third byproduct, depending on the fuel used, is methane or another non-earth-friendly substance. But the most basic fuel cell combines hydrogen and oxygen to produce pure water. This simple, long-lasting device with no moving parts […]

Measuring efficiency in solar photovoltaic cells
Single-junction solar cells have a maximum theoretical efficiency of 33.16%, the Shockley-Queisser limit. But there are work-arounds that permit solar array designers to surpass that limit on a square-foot basis. The maximum solar conversion efficiency of around 33.7% happens at a 1.34 eV band gap and is subject to several assumptions. By way of review, […]
