VectorStar 4 Port Broadband VNA ME7838E4/A4/D4

The VectorStar series of broadband Vector Network Analyzers offer the widest available 4-port single sweep measurements from 70 kHz to 110, 125, 145, and 150 GHz with mmWave bands up to 1.1 THz

The VectorStar ME7838A4/E4/D4 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, is the only broadband system with positive raw directivity in all bands. The result is better calibration stability and better measurement stability with significantly longer time between calibrations for accurate measurements and improved productivity. The new ME7838D4 takes high performance 4-port broadband measurements to a new level by incorporating the Anritsu MA25300A mmWave module. The MA25300A module combines Anritsu developed Nonlinear Transmission Line (NLTL) technology in a small, compact high performance mmWave module with a 0.8 mm test port connector for measurements up to 145 GHz.

All VectorStar broadband systems include an RF VNA architecture using bridges instead of couplers to extend frequencies down to the RF bands (operational to 40 kHz) for near-DC analysis with excellent dynamic range.

AWR Connected™ to Anritsu VectorStar
Anritsu's VectorStar Vector Network Analyzer (VNA) uniquely combines design and measurement by including AWR's Microwave Office® design software as a standard feature within the instrument, as a separate application on your desktop.

You now have access to all of the design tools essential for high-frequency IC, PCB, and module design at your fingertips, right on your VNA, including:

  • Linear circuit simulators
  • Electromagnetic (EM) analysis tools
  • Integrated schematic and layout

The integration of high-frequency design tools within high-performance VNAs is the way of the future - but it's available today, only from Anritsu and AWR.
