Whether a device is dealing with chirped pulses, phase-modulated waveforms, or pulse position modulation, the R&S FSWX-KM700 pulse analysis option tracks how well it handles the advanced modulation schemes utilized by today’s most agile radars.
Rohde & Schwarz Upgrades FSWX Analyzer for High-Stakes Radar Jammer Testing
Electronic warfare is a high-stakes game of cat and mouse. As radar systems grow more sophisticated, so must the technology used to spoof them. To help engineers keep pace, Rohde & Schwarz has rolled out the R&S FSWX-KM700 pulse analysis option, a major software upgrade that transforms its FSWX signal and spectrum analyzer into a dedicated workstation for testing Digital Radio Frequency Memory (DRFM) jammers.
DRFM jammers are designed to deceive and spoof enemy systems by intercepting radar emissions, digitizing them, and firing them back with precisely controlled delays, phase shifts, and frequencies.
But as modern radars adopt increasingly agile and complex waveforms, mimicking them is harder than ever. A jammer’s deception signal is only credible if it flawlessly reproduces the original radar burst; even the slightest hiccup in timing or amplitude can give the game away.
That’s exactly the problem the new R&S FSWX-KM700 software aims to solve.
Leveraging the FSWX analyzer’s innovative dual-channel, phase-coherent architecture, the new tool gives engineers a granular look at a jammer’s actual performance.
It meticulously measures critical pulse parameters such as width, amplitude, rise and fall times, overshoot, and duty cycle,so developers can ensure their jammers are reproducing radar envelopes with pinpoint accuracy.
Moving Beyond the Single Pulse
The software isn’t limited to isolated bursts; it evaluates entire pulse trains. Engineers can extract pulse repetition frequency spectra and track pulse-to-pulse variations to verify complex timing patterns.
Whether a device is dealing with chirped pulses, phase-modulated waveforms, or pulse position modulation, the FSWX-KM700 tracks how well it handles the advanced modulation schemes utilized by today’s most agile radars.
To help users cut through the noise, the system features highly customizable triggers based on amplitude, pulse width, or user-defined patterns. This allows engineers to isolate specific events within a massive pulse train and focus solely on the most relevant parts of the signal.
Tracking Long-Term Consistency and Latency
Understanding a jammer’s behavior in a single moment isn’t enough, which is why the R&S FSWX-KM700 aggregates data over long measurements. This helps engineers prove whether a jammer performs consistently over time or if timing and modulation errors creep in under specific conditions.
The software also introduces tailored displays designed specifically for DRFM electronic attack analysis. Engineers can use “capture vs. time” views to measure a jammer’s precise latency, the exact response time between a radar stimulus and the jammer’s reaction.
Meanwhile, individual pulse parameter displays ensure that the jammer itself isn’t introducing any unwanted frequency or phase distortions.
Ultimately, the R&S FSWX-KM700 packages phase-coherent multi-channel analysis, pulse sequence tracking, and segmented capture functions into a single instrument. For engineers testing the limits of signal fidelity in modern electronic warfare, it offers a highly specialized, streamlined way to ensure DRFM jammers are field-ready.
