Spectrum Analyzer Seesii Tinysa Ultra+ ZS407 100kHz-7.3GHz Portable

Description

Product Overview

The Seesii Tinysa Ultra+ ZS407 is engineered for professionals who demand precise, wide‑band RF analysis in a handheld form factor. Covering a frequency range from 100 kHz up to 7.3 GHz, the device bridges the gap between low‑frequency signal monitoring and high‑frequency spectrum diagnostics, making it suitable for emerging 5G NR, Wi‑Fi 6E, satellite, and other high‑frequency applications. Its 32 GB internal storage records raw trace data, while a USB‑C port enables real‑time data streaming to a PC or mobile device via the TinySA‑APP. The unit weighs just 13.76 oz and measures 6.69 × 4.33 × 2.05 in, offering a balance of portability and durability for field engineers.

Beyond passive analysis, the Ultra+ integrates a versatile signal generator capable of producing sine waves from 100 kHz to 900 MHz, square waves from 800 MHz to 6.3 GHz, and mixed‑signal outputs between 4.4 GHz and 6.3 GHz. This dual‑functionality eliminates the need for separate equipment, streamlining test setups and reducing overall cost. The device is calibrated up to 8 GHz, ensuring accuracy even when operating near the upper limits of its specified range. A rechargeable 5000 mAh battery supplies up to ten hours of continuous operation, a critical advantage for remote troubleshooting and on‑site verification.

Usage

Field technicians deploying RF interference mitigation solutions will find the Tinysa Ultra+ indispensable. Its compact size allows placement on rooftops, vehicle dashboards, or handheld operation while scanning crowded spectrum environments. The analyzer excels in satellite communication maintenance, where precise frequency alignment is essential for uplink and downlink integrity. In laboratory settings, engineers can use the built‑in signal generator to validate filter performance, assess antenna gain, or simulate interference scenarios without additional hardware.

Educational institutions also benefit from the device’s intuitive interface and comprehensive data logging. Students can conduct hands‑on experiments ranging from basic harmonic analysis to advanced modulation studies, all while learning to interpret real‑time spectral data. The USB‑C connection supports firmware updates, ensuring the instrument stays current with evolving standards and software improvements.

Because the unit runs on a single AA battery (included) for auxiliary functions and a rechargeable pack for primary operation, it remains functional in environments where power sources are limited. Whether you are a telecom field engineer, a satellite technician, or a hobbyist exploring the RF spectrum, the Ultra+ adapts to diverse use cases with minimal setup time.
