VectorStar ME7838A4 寬頻系統利用簡約的毫米波模組和業界最佳的校準穩定性，提供了高性能的 4 埠測量。市場上的其他寬頻系統仍然只提供原始性能和關鍵頻帶上的負向性，而包含 ME7838A4 4 埠系統的 ME7838 系列是提供所有頻帶原始正向性的唯一寬頻系統。因此這一系列會有更好的校準穩定性和更好的測量穩定性，並且大幅延長了校準間隔時間，提高了測量準確度和生產力。
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.
