X-COM Systems is offering a new application note entitled, Benefits of Time-Synchronized Dual-Channel Spectrum Recording. The white paper describes a technique for recording two channels of spectrum synchronized in time, from seconds to minutes or even longer. Many applications, such as analyzing aircraft radar cross-section and monitoring of wireless networks to find and identify interference, can significantly benefit from this process. A signal analyzer is not always practical in such applications, as the breadth of spectrum to be analyzed often exceeds its capture bandwidth, causing signals of interest to be missed. Signal analyzers are also designed to store only recordings of short duration, so they are unlikely to detect signals that occur randomly or intermittently. However, with two signal analyzers acting as front end, preselector and digitizer, streaming their output to a spectrum record and playback system, accounted for, all transient emissions can be. Available for download at the company’s web site, Application Note 101: Benefits of Time-Synchronized Dual-Channel Spectrum Recording details the dual-channel measurement technique and provides examples of how and where it can be used.
