Radar systems are used for military and civilian aviation, weather system tracking and automobile traffic control to name a few. All of these systems have several things in common, including transmitting and receiving reflected RF energy from a distant object to calculate speed, distance and sometimes elevation. These systems are very important for our safety and require accurate power measurement. This article will focus on aviation or ranging type radar that uses bursts, or chirps of pulse modulated waveforms for fine object detail, and has sensitive receivers for low noise measurements.

Boonton’s 4540 Series RF Power / Voltage meters provides highly detailed waveform traces for accurate measurements, efficient alignment and detailed analysis of linear and pulsed RF components and circuitry.

Deep-level transient spectroscopy (DLTS) is an experimental tool for studying electrically active defects in semiconductors. DLTS allows researchers to define defect parameters and measure the concentration of those defects in space charge region of simple electronic devices, typically Schottky diodes or p-n junctions.
