VectorStar ME7838A4 宽带系统利用紧凑的毫米波模块和业界最佳的校准稳定性提供了高性能 4 端口测量。市场上的其他宽带系统仍然只提供原始性能和关键频带上的负方向性，而包含 ME7838A4 4 端口系统的 ME7838 系列是提供所有频带原始方向性的唯一宽带系统。因而会有更好的校准稳定性和更好的测量稳定性，并且大幅延长校准间隔时间，提高测量准确度和生产力。
The VectorStar ME7838x4 Broadband systems provide high performance 4-port measurements utilizing compact mmwave modules with industry-best calibration stability. While other broadband systems continue to provide raw performance with negative directivity in critical frequency bands, the ME7838 series, which includes the 4-port systems includes broadband systems with positive raw directivity. The result is better calibration stability and better measurement stability with significantly longer time between calibrations for accurate measurements and improved productivity. The new ME7838G4 takes high performance 4-port broadband measurements to a new level by incorporating the Anritsu MA25400A mmWave module. The MA25400A module combines Anritsu developed Nonlinear Transmission Line (NLTL) technology in a small, compact high performance mmWave module with a 0.6 mm test port connector for measurements up to 220 GHz.
