Features: brand new and high quality Up to 3GHz vector network analyzer, designed in collaboration with OwOComm. Upgrade metal for shell, which is designed to reduce the external interference and improve the measurement accuracy. Use 0.5ppm TCXO to ensure the accuracy of the high frequency measurement frequency. The full metal for shell can fully protect the internal precision circuit, and the for protection of the external interface is taken into account. Custom high-performance SS405 cable provides good stability, phase stabilization performance, high-performance calibration kit to ensure that the calibration SWR is less than 1.03 up to 3GHz. Specifications: Frequency range: 50kHz-3GHz Frequency error: <2ppm Frequency and temperature: <0.5ppm System dynamic range (Calibration): 70dB (up to 1.5 GHz), 60dB (up to 3GHz).
