Datasheet

Overview

The Anritsu VectorStar ME7838AX is a 2-port broadband vector network analyzer system that provides single-sweep coverage from 70 kHz to 125 GHz, with guaranteed specifications, at a 1 mm coaxial test port. The system is operational from 40 kHz to 125 GHz.

The broadband configuration is built from an MS4647B VectorStar VNA (70 kHz to 70 GHz), a 3739C Broadband mmWave Test Set with interface cables, and two 3743AX broadband mmWave modules. The modules use Anritsu Nonlinear Transmission Line (NLTL) technology, with thin film multipliers, receivers and couplers placed at the test port for raw directivity and calibration stability. Port power control is provided by the base VNA below 54 GHz and by the 3743AX module above 54 GHz.

The compact mmWave modules are intended for positioning on wafer probe stations and are compatible with major probe stations. Kelvin bias tees provide sense and force capabilities close to the device under test.

Configurations and upgrades

In addition to the broadband configuration, the ME7838AX can be configured with banded millimeter-wave modules providing waveguide output from 50 GHz to 1.1 THz, either extending the broadband system or operating as a waveguide-only system. A 4-port variant, the ME7838A4X, is also available. The ME7838AX can be upgraded to 145 GHz and to 220 GHz.

Software options

The system supports VectorStar options including time domain, Universal Fixture Extraction, noise figure and differential noise figure measurements with the 3744x-Rx receiver up to 125 GHz, IMDView, DifferentialView, eye diagram and spectrum analysis (Option 49).
