MaxwellonTW4208 series Modular Spectrum Analyzer frequency range covers from 9kHz to 8G/18GHz. The integrated design of highly integrated RF front-end and integration with digital processing enables it to have ultra-small size and independent signal processing capabilities, especially suitable for microwave test system integration and signal monitoring sensor applications. The maximum real-time bandwidth of 40MHz meets the test of common radio signals such as mobile communication, TV and WiFi, and the 145MHz analog IF output provides users with a variety of test options. The spectrum analyzer module itself has signal analysis and processing capabilities, and the PC host computer can directly obtain the measurement results, and users can flexibly carry out secondary development according to their needs. Products are widely used in aerospace, microwave communication, satellite navigation, radar detection, electronic detection and countermeasures, precision guidance and other fields.
