TinySA ZS-406 Spectrum Analyser by Zeenko

Unlock the RF Spectrum Anywhere! The TinySA Zeenko ZS-406 is a powerful and incredibly compact handheld tool, perfect for technicians, engineers, radio amateurs, and electronics enthusiasts. This versatile device functions as both a spectrum analyzer and a signal generator, offering a wealth of features in a tiny footprint, making advanced RF analysis more accessible than ever.

Use in EMI Investigations: The portable TinySA Zeenko ZS-406 spectrum analyzer serves as a highly practical tool for on-site EMI investigations in industrial settings, enabling technicians to efficiently identify and troubleshoot both conducted and radiated electromagnetic disturbances. For conducted emissions, typically assessed in the 150 kHz to 30 MHz range, the TinySA ZS-406 can be utilized with standard accessories like Line Impedance Stabilization Networks (LISNs) and RF current probes to measure noise on power lines and cables. Its adjustable Resolution Bandwidth (RBW) settings, which for the ZS-406 typically range from around 200Hz to 850kHz, allow for diagnostic work aligning with common requirements (such as 9 kHz RBW for conducted emissions scans), and its peak detectors are useful for quickly identifying problem frequencies. When investigating radiated emissions, often examined in the 30 MHz to 1 GHz range and beyond (the ZS-406's Ultra mode extends its capability to several GHz), this handheld analyzer can be paired with appropriate antennas to assess fields emanating from equipment. While not a substitute for full compliance testing in certified anechoic chambers, the TinySA ZS-406's portability makes it exceptionally effective for diagnostic "sniffing" using near-field E-field and H-field probes. This allows for the direct pinpointing of EMI leakage from components, PCB traces, cable penetrations, or enclosure seams directly on the factory floor or in situ, providing crucial relative insights for effective troubleshooting.
