“Performance” 2- and 4-port VNAs focus on affordability, speed sweeping

June 05, 2015 // By Graham Prophet
Anritsu’s MS46500B series brings industry first simultaneous forward and reverse sweeping VNAs to variety of measurement applications.

In the ShockLine family of vector network analysers (VNAs), the MS46500B series claims best-in-class dynamic range and maximum output power. Applications can range up to 8.5 GHz, including designing and manufacturing mobile network equipment, mobile devices, automotive cables, high-speed data interconnects and system integration components.

The MS46500B comprises the 2-port MS46522B and 4-port MS46524B models, and expands the ShockLine family to a broader spectrum of RF test applications. Each instrument features an independent source per VNA port, and all the sources can sweep at the same time for measurement of forward and reverse s-parameters simultaneously. This unique Simultaneous Sweep feature allows 2-port measurements to be conducted twice as fast and 4-port measurements 4x as fast. With shorter test times, the MS46500B series significantly improves throughput in manufacturing environments.

With its dynamic range, low trace noise, and fast sweep speed, the MS46500B series addresses the S-parameter and time-domain measurement requirements of a complete range of passive device applications. Faster frequency and time domain measurements can be achieved with a time domain with time gating option. In this configuration, the 4-port MS46524B VNA can conduct single-ended, mixed-mode, and Time Domain Reflectometry (TDR) measurements on multiport and differential devices.

The MS46500B series is housed in a 3U high chassis to fit in conventional rack systems and the VNA’s short depth allows more bench space for cabling and the DUT. The MS46500B VNAs use industry standard LAN communications for robust remote control in production test environments.

ShockLine software also provides a powerful graphical user interface (GUI) for manual test and engineering use. When attached to a user-supplied touchscreen monitor, the full-featured GUI provides comprehensive capabilities, including network extraction, embedding/de-embedding networks, and time domain with time gating. Developing and troubleshooting test programs are made easier, due to advanced marker and limit lines features.
