This device integrates a spectrum analyzer and an signal generator. Connects to a computer (Win7/Win10) via USB Type-C interface, powered directly by USB, enabling signal generation and spectrum measurement in the 35 MHz - 4400 MHz frequency band. It is a cost-effective and ideal tool for , education, production, and field operations. High Integration: One device combines a spectrum analyzer and a signal generator, saving cost and space. Portable Power Supply: Powered and communicates via USB Type-C interface; no external power supply required, plug and play. Superior performance: Fast scanning speed (2800 points/second), dynamic range >50dB, and background noise as low as -60dBm. Wide frequency coverage: Available in multiple versions, supporting a wide range of tests from extremely low frequencies to 6GHz. Specifications Interface and Power Supply: USB Type-C (Communication and Power Supply) Power Supply Current: Standby ≤100mA, Scan ≤350mA Supporting Software: WinNWT4 for 7/10 Scanning Speed: . 2800 points/second Resolution Bandwidth (): 120kHz (Dynamic Scan) Dynamic Range/Scan Recording Ratio: > 50 dB Output Power (Signal Source): . 0 dBm Maximum Input Level (Spectrum Analyzer): ≤ +10 dBm Background Noise Floor: . -60 dBm Spectrum Analysis Range: 35 MHz - 4400 MHz Signal Output Range: 35 MHz - 4400 MHz Application: Wireless Communication and Teaching: Signal testing and debugging of devices such as WiFi, Bluetooth, Zigbee, LTE, and walkie-talkies. Circuit Development: Frequency response testing of components such as filters, amplifiers, antennas, and matching circuits.
