Solutions that Support the Entire System Development Lifecycle
Use powerful DSP technology that supports your system development lifecycle, from electronic warfare algorithm prototyping to simulation of ultrawide bandwidth RF environments.
Today, the dynamic congestion contained within the electromagnetic spectrum from other emitters, jammers, and interferers demands higher fidelity instruments to accurately simulate the environments represented in the field to ensure radar electronic protection systems are fully tested, so our military forces can detect realistic threats and stay out of harm’s way.
Engineers need technology and integrated measurement tools that accurately capture and recreate the physical and electromagnetic environment exposed during field operations. These tools are used in all stages of development, from rapid prototyping, to verification & validation, through mission readiness test.
Capture and Recreate RF Environments in New Ways
On the analysis side, Tektronix technology is used to capture, visualize and trigger on threats and electronic countermeasure responses. Discover the true RF signature of a signal of interest (SOI) in spectrum and analyze the physical characteristics of signals of interest even if they are hidden within or are under other signals. Record, stream and tag SOI in real time during the most challenging demonstration and validation events.
When it comes to simulation, radar design measurements call for exhaustive, realistic stimulus signals. Tektronix technology is capable of directly generating complex radar signals through the entire Ku band with breakthrough DAC conversion performance.

Electronic Warfare Algorithm Prototyping
The nature of electronic warfare requires engineers to constantly enhance their systems, which often puts a lot of pressure in demonstrating the functionality of new algorithms.
In the past, one effective way to reduce the timeline and budget of producing a prototype was to use commercial off the shelf (COTS) spectrum analysis equipment with the ability to stream I/Q data, combined with custom hardware that would process the digital signals and generate the appropriate response.
Tektronix’ RSA7100 Series avoids the use of custom hardware by combining the digitization and customization tasks. And for parallel testing, our Series 5 and 6 MSO oscilloscopes and SignalVu-PC software provide multichannel capabilities.
RF Record & Playback
The ability to capture signal activity continuously over long periods, digitize and store it, and play it back greatly benefits spectrum management, RF interference analysis, signal acquisition, product testing and validation, RF system design, communication security, and academic research. The high performance RSA7100B from Tektronix outperforms spectrum analyzers with far more limited storage and analysis capabilities. Unlike others that can only be employed as the "front end" of recording because of the limited internal storage (SSD size dependent), the RSA7100B can continuously record and store signal-capture data for hours or days, enabling data capture and analysis to be performed with the same hardware.
Debugging RF systems today requires an understanding of the complex interplay between RF, digital, and time domain signals. RF noise from power and digital lines make troublesome sources without the tools to track them down and correlate behavior across various systems. Tektronix offers complete, single instrument solutions that allow you to fully understand the signals you’re creating, need to work with, or need to work around.
When compliance is required, pre-compliance testing for violations can save project timelines and budgets by allowing you to catch and fix issues without regulator testing. Together, Tektronix hardware and software allow automated testing with built-in standards, and even the ability to define your own, custom requirements with configurable frequency ranges and limit line tables.

Electronic Warfare FAQ
What is electronic warfare?
Electronic warfare (EW) is the use of electromagnetic energy, or the manipulation of the electromagnetic spectrum, to defend against, disrupt, or attack enemy forces. EW operations can include actions such as jamming communications, detecting radar signals, and manipulating electronic devices. It involves the use of electronic devices to confuse or disable an opponent's electronic systems, or to enhance the effectiveness of friendly systems. Electronic warfare is an important component of modern warfare, as it can provide a significant advantage to the side that is able to control the electromagnetic spectrum.
What are the most common approaches for ew testing?
The most common approaches for Electronic Warfare (EW) testing are:
- Field Testing: This involves conducting testing in real-world conditions with actual equipment and operators. The objective is to evaluate how the system performs in the environment where it will be used.
- Laboratory Testing: This involves testing the equipment in a controlled environment, such as a laboratory, to evaluate its performance under ideal conditions. Laboratory testing allows for precise measurements and repeatable results.
- Modeling and Simulation: This approach involves creating a computer model of the system and simulating its operation in various scenarios. Modeling and simulation can be used to test the system's performance in situations that may be difficult or dangerous to replicate in the real world.
- Hardware-in-the-Loop (HIL) Testing: This approach involves connecting the system to a simulation environment that mimics the actual hardware and environment. HIL testing can be used to evaluate how the system interacts with other equipment and to test how it responds to different scenarios.
- Live-Fly Testing: This involves testing the system in flight, often in conjunction with other aircraft and systems. Live-fly testing allows for evaluation of the system's performance in real-world conditions.
Each approach has its own advantages and limitations, and the choice of approach will depend on the specific needs and objectives of the testing program.
What are the biggest challenges in ew system testing?
There are several challenges in Electronic Warfare (EW) system testing that can make it difficult to accurately evaluate the performance of EW systems. Some of the biggest challenges include:
- Complex operating environment: EW systems must operate in complex and rapidly changing electromagnetic environments, making it difficult to predict how they will perform in real-world conditions.
- Limited access to testing environments: EW testing requires access to specialized testing environments, such as anechoic chambers, which can be expensive and difficult to schedule.
- Difficulty in replicating real-world scenarios: It can be challenging to replicate real-world scenarios in testing environments, which can limit the ability to evaluate the system's performance in complex situations.
- Rapidly evolving threats: EW systems must be able to adapt to new and evolving threats, which can be difficult to simulate in testing environments.
