Datasheet

Overview

The VectorStar ME7838D4 is a 4-port broadband vector network analyzer system that provides single-sweep coverage from 70 kHz to 145 GHz and is operational from 40 kHz to 150 GHz. It combines an MS4647B VectorStar VNA with an MN4697C 4-port test set, 3739C and 3736B broadband test sets and four MA25300A millimeter-wave modules with 0.8 mm coaxial test ports.

The MA25300A modules use Anritsu-developed Nonlinear Transmission Line (NLTL) technology, with thin-film multipliers, receivers and couplers at the test port. Anritsu states that this architecture gives positive raw directivity and therefore improved calibration and measurement stability over 24 hours, with longer intervals between calibrations. The modules are compact and light enough for direct positioning on wafer probe stations, and the system supports real-time electronic power leveling at millimeter-wave frequencies.

Waveguide and millimeter-wave configurations

The ME7838D4 can also be configured for 4-port waveguide-band operation from 50 GHz to 1.1 THz. E and W bands are covered with MA25300A modules plus coax-to-waveguide adapters, or with 3744A-EE and 3744A-EW modules. Higher bands use Virginia Diodes (VDI) frequency extension modules. The waveguide setup can extend the broadband system or run as a waveguide-only system.

Options

Available options include Time Domain, Universal Fixture Extraction, Dual Source Architecture, Noise Figure (with the 3744A-Rx receiver for 30 GHz to 125 GHz), DifferentialView, IMDView, Eye Diagram, Differential Noise Figure and Spectrum Analysis. SC8215 and SC7287 Kelvin bias tees provide sense and force connections close to the DUT.
