EVM Confidence with Simplified Satellite Testing

EVM problems in satellite testing are rarely caused by a single issue. More often, it’s the combination of LO phase noise, I/Q imbalance, PA behaviour, filtering, and setup inconsistencies that makes measurement confidence difficult. This blog does a good job breaking down those contributors and explaining how a cleaner measurement environment can help reduce uncertainty during debug and validation. 🔗 https://lnkd.in/ePQJFFH4 #SatelliteTesting #EVM #RFEngineering

In LMR systems, output power alone doesn’t define performance. Signal integrity does. Crescend amplifiers are engineered to maintain: – Stability under variable loads – Consistent output across operating conditions – Clean amplification without added distortion Because in mission-critical communication, clarity is the performance metric that matters.

Struggling with Third‑Order Intercept (TOI/IP3) measurements? Nonlinearities in amplifiers and mixers create intermodulation products that can ruin your system's performance. But testing IP3 comes with real challenges: 🔹 Extrapolation errors from operating near compression 🔹 Test‑system induced distortion (signal generators & combiners) 🔹 High dynamic range needs for high‑linearity DUTs Our latest application note walks you through a practical, step‑by‑step solution using SIGLENT's spectrum analyzers and vector signal generators – including a one‑click TOI measurement mode that simplifies the entire process. ✅ Verify linear operating regions ✅ Avoid false IM3 readings ✅ Get reliable IP3 results without guesswork 👉 Download the note or read more here: https://lnkd.in/gnM2fRtQ #RF #SpectrumAnalyzer #TOI #IP3 #Intermodulation #Siglent #TestAndMeasurement

🔊 Why 16.384 MHz OCXO is the ears of subsea leak detection Detecting pipeline leaks underwater comes down to one thing: timing precision. High‑frequency acoustic sensors rely on a stable reference clock to catch the subtle frequency shifts of escaping fluid. That's where a 16.384 MHz OCXO becomes critical. ✅ Sub‑microsecond stability for accurate signal sampling ✅ Resolves tiny frequency changes that indicate a leak ✅ Operates reliably in cold, high‑pressure environments A microsecond of drift, and critical leak signals can disappear into noise. With a high‑stability OCXO, engineers get early, actionable detection — before a small leak becomes a disaster. 🔊 Precision that listens. 👉 Learn more: www.DynamicEngineers.com #OCXO #SubseaEngineering #LeakDetection #AcousticSensors #SignalProcessing #UnderwaterTech #FrequencyControl #RFEngineering #DataAcquisition #PipelineMonitoring #MWJournal #EverythingRF #SignalIntegrityJournal #RFFilters #TimingModules #Oscillators #CMSE2026 #DynamicEngineers #EverythingRF

A subsea leak doesn’t scream. It whispers. Detecting it means hearing a tiny frequency shift – microsecond drift and that whisper vanishes into noise. That’s why 16.384 MHz OCXO matters. It’s not just a clock. It’s the ears of the operation. For anyone working in subsea monitoring or acoustic sensing – this one’s worth a read. #SubseaMonitoring #OCXO #LeakDetection #PrecisionTiming #AcousticSensing #DynamicEngineers #EverythingRF

Active Voltage Contrast (AVC) setup is the critical first step in any Electron Beam Probing analysis—and getting it right depends heavily on beam conditions. At #ASMC2026, I'll be presenting some work between myself, Rainer Arnold, Marc Heinemann, and Markus Reichel on "Beam settings optimization for Active Voltage Contrast of Cu and Al wiring". We systematically investigate how beam energy and detector configuration affect sensitivity and feature detectability in copper interconnects, leveraging annular detector capabilities on a modern SEM. If you're working on similar problems, I'd love to connect to discuss more. #PVC #voltagecontrast #nanoprobing #semiconductormanufacturing #conference2026 #albany #teamzeiss
