EW receiver mission data files can contain hundreds of emitters with thousands of modes and beams that must be tested by simulation at RF. Often, these emitters, their modes and beams are listed on intelligence databases and must be imported from a spreadsheet into to an emitter simulation application such as the R&S®Pulse Sequencer software. For this purpose, the R&S®Pulse Sequencer software offers an internal script editor which allows to import user data and automatically generate emitter, sequence or platform configurations that can then immediately be played into RF without any additional software. Furthermore, the R&S®Pulse Sequencer offers a SCPI recorder tool to collect manual entries during scenario data creation into a list of corresponding SCPI commands. This list of commands can easily be used to create user defined scripts that can either run in the internal script editor or an external software (e.g. Matlab, Python).

Primer

A power sensor is a fundamental measurement tool in RF engineering. However, today's marketplace is filled with myriad choices, and many are making bold claims about attributes such as measurement speed and readings per second. As a result, it can be difficult to cut through the hyperbole and determine which sensor will actually meet the requirements of a specific measurement.This primer outlines the basics of RF power sensors and highlights a few key characteristics that will help you select the best one for each application. The narrative has three parts. First, we focus on choosing the right type of sensor: multipath, wideband, average power and thermal can satisfy slightly different measurement needs. The second section covers the five major attributes of sensor performance, and what to look for relative to your requirements. Finally, we outline three ways to integrate a sensor into your measurement application.

Keeping an ATSC (or ATSC Mobile DTV) single-frequency network (SFN) running smoothly not only requires that every single TV transmitter functions properly – the RF performance criteria echo pattern and frequency deviation also have to be strictly complied with. The R&S®ETL TV analyzer enables operators to check these crucial RF parameters at a glance with unmatched precision. The patented implementation achieves an echo delay resolution of one nanosecond, which is nearly a hundred times higher than in conventional approaches. This allows more precise control and adjustments of the several transmitters within the ATSC (or ATSC Mobile DTV) SFN and thus helps to ensure excellent coverage for the receivers.

Secondary surveillance radar (SSR) bridges the gap between communications systems and classic radar systems. Despite the increasing capabilities of mobile communications, SSR remains a major component in airspace surveillance. State-of-the-art methods such as Mode S reply enhance SSR with broadcast-like capabilities and enable airports in remote locations to surveil the airspace even if no radar is available. More advanced techniques such as automatic dependent surveillance broadcast (ADS-B) utilize the infrastructure provided by a Mode S reply transponder to provide even more information for ground control and other aircraft.
