The R&S®Pulse Sequencer software offers a powerful mechanism to model sequences that are often required for meaningful radar receiver test cases. The sequences can consist of many individual elements, such as pulses defined by the software or imported waveform segments. The software’s powerful interpulse modulation mechanism gives the user full control of each single element.

The need to properly represent the ever changing complexities of the RF environment across communications, surveillance, electronic support measures (ESM) and signal intelligence system (SIGINT) with the advances of signal complexity and bandwidth, requires an enormous test and measurement effort.Extensive field tests are often applied to verify the performance and capabilities under preferably natural but controlled conditions. This is both costly and requires a great deal of time.RF signal environment generation using Test & Measurement equipment brings field tests into the laboratory, where a controlled, cost-effective and reproducible environment exists. The R&S®Pulse Sequencer software is a versatile tool to generate arbitrary and realistic RF signal scenarios ensuringsystem readiness for the real operational world.This application note introduces the R&S®Pulse Sequencer software, explains several examples that are applicable for research, development, before operational and during life-time test in detail, and guides you through the necessary steps, to generate a self-defined, arbitrary real life RF signal environment.

Development of modern EW systems is a complex and expensive process, that requires thorough testing against all requirements during all phases of development. To keep cost under control, system level testing in the lab is key and brings several advantages: test cases can be reproduced under the exact same conditions as often as necessary. System level testing in the lab is often performed in a hardware-in-the-loop (HIL) environment. This application note provides some insight into generating radar signals for hardware-in-the-loop testing with the R&S®SMW200A. An introduction to HIL testing and realtime operation of the R&S®SMW200A is given. The hardware and software interface, the PDW format and synchronization and timing mechanisms are described. Additionally, various example scenarios and detailed information about intermediate calculations are provided. The application note also provides information about system requirements for advanced PDW streaming with multiple emitters on multiple parallel streams.

EW receivers are tested in the lab at RF to discover problems before flight testing. This eliminates cost and schedule risk. Flight testing can cost tens of thousands of dollars per hour and must be scheduled many months in advance. In contrast, using test equipment to test at RF might require a certain upfront cost but provides a readily-accessible capability to simulate radar threats at RF for a long time. This application note explains how the angle-of-arrival (AoA) capabilities of EW receivers can be tested with commercial off-the-shelf (COTS) RF test equipment. Topics covered are the generation of scenarios, instrument setup, and setup calibration. We will use a radar warning receiver (RWR) as a proxy for a generic EW receiver in this application note.

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).
