AURSINC TinySA Ultra+ ZS407 7.3GHz Spectrum Analyzer with 50W RF Attenuator

Features

• High-Precision Spectrum Analysis: The TinySA Ultra+ ZS407 delivers excellent RF measurement performance with a 100kHz to 7.3GHz frequency range, covering most common ham radio and wireless signal bands. It supports fine RBW adjustment and high receiving sensitivity, capturing both faint ambient signals and strong local transmissions clearly for accurate frequency and power readings
• Expand Testing Range with 50W Attenuator Bundle: This kit includes a 50W N-type RF attenuator that safely reduces high-power signals to the compatible input range of the ZS407. It effectively protects the analyzer from overload damage and extends your measurement capabilities to high-power transmitter testing, repeater verification and device calibration scenarios
• Stable & Durable Attenuator: Rated for 50W power handling across DC-3GHz, this attenuator provides 50dB fixed attenuation with 2.5dB tolerance, 50 impedance and a maximum 1.20:1 VSWR for low signal reflection. Made of anodized aluminum, it offers excellent heat dissipation and corrosion resistance for long-term, maintenance-free high-power operation
• Portable Handheld Design with Multi-Mode Support: Equipped with a high-resolution color display and built-in rechargeable battery, this compact spectrum analyzer works seamlessly for both bench work and on-site field testing. It features multiple operation modes including full spectrum sweep, zero span analysis and signal peak tracking, and supports PC connection for data export and in-depth post-processing
• 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
