Product Details
✓50W N-Type Attenuator Spec: Rated for DC–3GHz operation, it provides 50dB of fixed attenuation with ±2.5dB tolerance, matched to 50Ω impedance and a maximum 1.20:1 VSWR for minimal signal reflection and consistent, predictable power reduction. It reliably steps down high-power transmitter and repeater signals to the analyzer's safe input range, preventing permanent overload damage
✓RF Attenuator for High-Power Testing: This bundle includes a professional 50W N-type RF attenuator to safely expand your testing scope. Its dry convection-cooled aluminum housing delivers excellent natural heat dissipation for continuous high-power operation, with standard N male input and N female output compatible with most RF equipment and feedlines
✓Upgraded Tinysa Ultra ZS406: Built on the latest HW V0.4.6, the AURSINC TinySA Ultra+ ZS406 features a 4.0-inch 480*320 touchscreen for intuitive, responsive operation. A pre-installed 32GB micro SD card supports convenient on-site data storage and sharing, while the built-in 5000mAh rechargeable battery delivers at least 3 hours of continuous runtime for both field and bench use
✓Wide Frequency Range & Precision Measurement: Covering 100kHz to 5.4GHz with Ultra mode extending up to 6GHz, this analyzer adapts to most common RF testing scenarios. It offers switchable resolution bandwidth from 200Hz to 850kHz, with the 200Hz minimum RBW clearly resolving adjacent signals and supporting SSB two-tone intermodulation testing
✓2-in-1 Analyzer: Doubles as a signal generator when not used for spectrum analysis. It outputs MF/HF/VHF sine waves from 100kHz to 900MHz, UHF square waves from 800MHz to 4.4GHz, and mixed signals from 4.4GHz to 5.4GHz. A built-in calibration signal generator supports automatic self-test and low-input calibration for sustained measurement accuracy
✓What You Get: 1x TinySA ULTRA+ ZS406 Spectrum Analyzer; 1x 50W Attenuator; 2x 30cm ALSR100 SMA cables; 1x USB Type-C data cable; 1x SMA-SMA barrel connector; 1x Lanyard and touch plectrum; 1x Antenna with SMA connector; 1x 32GB MicroSD card (pre-installed in the host); 1x Stylus Pen
✓Versatile Applications & Dedicated Support: Ideal for ham radio station setup, antenna tuning, signal interference troubleshooting, wireless device verification and RF electronics experimentation. Every unit undergoes full pre-shipment testing, and AURSINC provides technical support and after-sales service for all setup and operation issues
