Overview

The VectorStar ME7838x4 series consists of 4-port broadband vector network analyzer systems that use compact millimeter-wave modules to provide single-sweep measurements from 70 kHz to 110, 125, 145 or 220 GHz. Each system may also be configured with banded millimeter-wave modules for waveguide measurements up to 1.1 THz.

The ME7838 broadband systems are designed for positive raw directivity across the band. According to Anritsu, this improves calibration and measurement stability, allowing longer intervals between calibrations. The millimeter-wave modules place thin-film multipliers, receivers and couplers at the test port and provide real-time electronic power leveling.

The series comprises four configurations: the ME7838E4X (70 kHz to 110 GHz, 1 mm coaxial output), the ME7838A4X (70 kHz to 125 GHz, 1 mm coaxial output), the ME7838D4 (70 kHz to 145 GHz, operational 40 kHz to 150 GHz, 0.8 mm coaxial output) and the ME7838G4 (70 kHz to 220 GHz, operational 40 kHz to 226 GHz). The ME7838G4 uses the Anritsu MA25400A mmWave module, which combines Nonlinear Transmission Line (NLTL) technology with a 0.6 mm test port connector for measurements up to 220 GHz.

Spectrum Analyzer and Noise Figure Options

The Spectrum Analyzer option (Option 49) adds spectral-domain measurements such as harmonics, spurs, distortion products and spectral occupancy, with single-sweep coverage from 70 kHz to 220 GHz using mm-wave modules. The noise figure option uses a cold-source technique, and the systems support the 3744x-Rx receiver for noise figure measurements to 125 GHz. A Differential Noise Figure option is also available for differential devices.

Software

Additional software options include Universal Fixture Extraction (UFX) for de-embedding, IMDView for intermodulation measurements with the internal combiner option, PulseView pulse measurements, DifferentialView for balanced 4-port analysis, and a trace-based eye diagram option.
