Synthetic Instruments: A New Horizon

Modular test components have been with us for many years in many forms. Going back to the early ’70s I can remember HP BWO oscillator/sweeper mainframes with their plug-in modules to address the various extremely high frequencies above 1 GHz. While this modularity in test equipment exists today, a...

Real-time Spectrum Analysis Streamlines Radar Pulse Testing and Diagnostics

Whether imaging an asteroid at a range of 55 million miles (88 million km), guiding a strategic defense missile to its target with a monopulse tracking radar or launching a rocket propelled grenade in the blink of an eye as a counter-measure, it is easy to see how radar...

A Multi-octave, Open-boundary, Quad-ridge Horn Antenna for Use in the S- to Ku-bands

This article introduces a new antenna design to be used in anechoic chambers as a source antenna for 3D pattern measurements. When measuring 3D patterns, the receiving antenna in the anechoic chamber must be able to sense the two orthogonal components ...
In a previous publication, 1 the author introduced a new dual-ridge horn that corrected the pattern problems of the traditional dual-ridge horn antenna. 2 All the parameters of this new horn, shown in Figure 1 , were measured and it was tested for use as an EMC immunity and...

An Efficient, Interactive Optimization Solution for Analog and RF Design

Optimization has been applied to circuit design for decades. IBM pioneered circuit simulation-based optimizer research in the 1960s and ’70s. In the 1980s, the University of California at Berkeley extended the research with more exotic algorithms and interactivity with programs such as DELIGHT and ECSTACY. During the same period,...

Anechoic Chamber Measurement Improvement

The well known and widely used "Termination-VSWR" method, used to measure the reflectivity of an absorber wall in an anechoic chamber, has been considerably modernized with the help of new vector network analyzers (VNA) and personal computers (PC), taking advantage of fast sweepers or synthesizers and of the time-domain...
