The 4025 Spectrum analyzer is a new generation of high-performance handheld Spectrum analyzer launched by Maxwellon. Its frequency measurement range covers 9kHz~20GHz. It is mainly used for the installation, commissioning, maintenance and interference troubleshooting of outdoor wireless communication equipment. It is small in size, light in weight, strong in environmental adaptability, flexible in power supply, and convenient in operation.
