Overview

The VectorStar MS4640B Series is Anritsu's premium vector network analyzer (VNA) line for S-parameter measurements of RF, microwave and millimeter-wave devices. The family comprises three 2-port models: the MS4642B (10 MHz to 20 GHz), the MS4644B (10 MHz to 40 GHz) and the MS4647B (10 MHz to 70 GHz). Each can be extended down to 70 kHz with Option 70, giving 70 kHz to 70 GHz coverage in a single instrument.

The platform is extendable through the ME7838 Series broadband configuration to 110 GHz, 125 GHz and 145 GHz from a single coaxial test port, using Anritsu-developed non-linear transmission line (NLTL) millimeter-wave modules, and through banded configurations up to 1.1 THz.

Measurement applications

IMDView provides a real-time display of intermodulation distortion measurements while IMD parameters are modified; combined with the internal combiner option it allows switching between S-parameter and IMD measurements without reconnecting the device under test. PulseView, used with the IF digitizing option, offers 2.5 ns pulse resolution and 100 dB dynamic range. DifferentialView, combined with the dual internal source option, analyzes differential devices while the phase and magnitude relationship of the two sources is adjusted.

Spectrum analysis and noise figure

The Spectrum Analyzer option (Option 49) adds spectral-domain measurements such as harmonics, spurs, distortion products and spectral occupancy, and is available on all baseband VectorStar models. With mm-wave modules it covers 70 kHz to 220 GHz in a single sweep. The noise figure option uses a cold-source technique, and a Differential Noise Figure option is available for differential devices.

Opto-electronic measurements

With the MN4765B O/E Calibration Module, the VectorStar supports optoelectronic measurements from 70 kHz to 40, 70 and 110 GHz at 850, 1060, 1310 and 1550 nm wavelengths. The MS4640B is supplied with a 3-year warranty.
