3 Radiation Hazards (RADHAZ) and How to Mitigate Risk Wednesday, September 8, 2021
If you are involved in military, aerospace or defense and have been around radar and communication systems, with high-power RF transmitters and high-gain antennas, you are probably aware of the many risks associated with Radio Frequency Radiation (RFR) Hazards. RF emissions from these systems have the potential to cause catastrophic damage to operations and maintenance personnel, ordnance and …
Monitoring the wireless spectrum for interference
3 System Design Challenges with Spectrum Monitoring Tuesday, September 7, 2021
The wireless spectrum is a finite commodity that is tightly regulated, managed and shared by all nations, manufacturers and citizens, who risk being fined if they are caught operating outside of what's regulated or licensed. The presence of interference or other signals of interest creeping into one's band of wireless spectrum is a daily occurrence to some and is of great concern to many who may …

Real-time Digital Signal Processing for Electronic Warfare Systems Monday, August 2, 2021
Evaluating and characterizing wideband communications, radar and electronic warfare systems in real time is challenging. Lacking a commercial off-the-shelf (COTS) alternative, some radar test teams stream test data to an inherently non-deterministic computing device such as a PC or laptop, inevitably leading to lost or missing data with no ability to verify that data is being recorded as expected …

Setting up an Automated Drone Detection System Using Spectrum Analyzers Tuesday, May 25, 2021
In a few short years, the number of drones, or unmanned aerial vehicles (UAVs), purchased has soared. In the US alone, the FAA projects the small model hobbyist UAV fleet will more than double from an estimated 1.1 million vehicles in 2017 to 2.4 million units by 2022. Worldwide, Teal Group’s World Civil UAS Market Profile and Forecast projected in 2018 that non-military UAS production (Commercial …
RF Power Triggering on Tektronix USB-RSAs Friday, January 15, 2021
All Tektronix Real-Time Spectrum Analyzers can be triggered based on a RF power threshold to help acquire specific signal bursts into memory for analysis. The family of USB-based RSAs include this capability. This blog will review some of the details of the RF Power trigger characteristics and settings to help you most effectively apply triggering to your application. This applies to the RSA306B …

What is Probability of Intercept (POI) and Why it Matters Thursday, September 10, 2020
One term we see quite often when breaking down spectrum analyzers is probability of intercept (POI). So, what is the definition of probability of intercept and why does it matter? When we see “probability of intercept” we should know that this term is almost always a contraction of the phrase “minimum event duration for 100% probability of intercept”. POI is the amount of time equal to “the …

8 Challenges with Wideband Radar Thursday, August 27, 2020
Increasingly, designers of radar and electronic warfare (EW) systems and components need to perform modulation and pulse analyses at wider bandwidths. Spectrum managers also need to record and analyze hours of wide bandwidth data. There area number of test and measurement challenges associated with these needs, however.    Here are eight challenges with wideband radar: Generating …
RSA7100B Wideband RF Signal Analyzer and Streaming Recorder Targets Challenging Real-World Test Scenarios Sunday, March 8, 2020
The new RSA7100B wideband RF signal analyzer and streaming recorder is now available, giving engineers a powerful solution for evaluating and characterizing wideband communications, radar and electronic warfare systems. This latest addition to the Tektronix family of real-time spectrum analyzers offers impressive specs and capabilities, including more than 2.5 hours of streaming RF storage at 800 …
How to Use Fast Frame on a Realtime Spectrum Analyzer Thursday, March 5, 2020
Fast Frame is a segmented memory acquisition mode designed to save memory when acquiring a large number of low duty cycle events. It is available on RSA5000, RSA6000 and RSA7000 Series realtime spectrum analyzers. A common application is with RADAR signals. RADAR signals are typically very low duty cycle – often 1% duty cycle or less. When acquiring a large number of consecutive pulses for …
Using Tektronix Real-Time Spectrum Analyzers for Automatic Drone Detection Friday, September 20, 2019
As hobbyist and commercial drones become ever cheaper and more ubiquitous, security and government officials around the world are stepping up efforts to detect the presence of drones or unmanned aerial vehicles (UAVs) in places where they don’t belong. Germany recently announced plans to install drone detection systems at its major airports to avoid runway and airport shutdowns when drones enter …
