Power: USB 5V 120mA, built-in 650mAh battery, maximum charging current 300mA.USB interface: USB type-C communication mode: CDC (serial).PCB: 54mm x 85.5mm x 11mm (without connectors, switches).If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring. The TX/RX method can measure the complete S11 and S21 parameters. For longer measurement, please connect external power supply or contact me to make a larger battery version. It includes a 2.8-inch touch screen and 500mAh battery, which can be used offline for 2 hours. This is a DIY product that provides perfect vector network measurement capabilities in the size of a credit card. The extended 300M-600MHz band provides better than 60dB of dynamics, and the 600M-900M band is better than 50dB of dynamics. The 50-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic. The metal shield is designed to reduce the external interference and improve the measurement accuracy. The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 50Khz-900MHz,300Mhz-900Mhz and 0.9-1.5Ghz. Simple and practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software.
