Please be kindly notedthe listed product is produced and distributed abroad and subject to the laws of its country of originPlease read down for 4 Type detailsType 1This is a DIY product with vector network measurement function. It includes a 8inch touching screen, TX/RX measurement, can determine the complete S11 and S21 parameters, if you need to get S12 and S22, you need to manually replace the transceiver port wiring.FeaturesThe PC control software can export Touchstone (snp) files, which can be used for various radio design and simulation software.The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz.The metal shield is designed to reduce the external interference and improve the measurement accuracy.The 50k300MHz frequency ranges of the si5351 direct output provides better than 70dB dynamic.The extended 300M600MHz band provides better than 50dB of dynamics, and the 600M900M band is better than 40dB of dynamics.Small and portable, easy to use, this project aims to provide an RF gadget but useful instrument for enthusiast.SpecificationsMaterial PCBColor blackMeasurement frequency 50KHz~300MHz (50KHz~900MHz, enable extended firmware)(the products will be updated with the latest firmware before shipping, the actual measurement frequency is 50KHz~900MHz)RF output 13dbm (maximum 9dbm)Frequency accuracy
