43.5GHz VNA delivers enhanced measurement stability

A modular 1-port Vector Network Analyser (VNA) that supports measurement frequencies up to 43.5GHz has been introduced by Anritsu. With 8GHz and 20GHz models also available in the series, the Anritsu ShockLine MS46131A USB VNA brings cost and efficiency advantages to measuring antennas and other 1-port 5G devices at sub-6GHz, as well as in the 28GHz and 39GHz millimeter wave bands.

Lightweight and compact, the MS46131A can be directly connected to the device under test (DUT), eliminating the need for interconnect cables. The result is reduced test costs and improved measurement stability.

The VNA can be configured for each user session on a port-by-port basis. A single PC can control up to two 1-port instruments for convenient dual site testing. Units can be easily moved between test setups, depending on the required port count.

Production uptime is also enhanced, as 1-port VNAs can be easily replaced, if needed, to keep test stations operational.

Beyond the USB connection to the external control PC running ShockLine software, the MS46131A also requires a 12V power supply.

An advantage of the external PC is that it makes test data more secure, as all the measurement results are stored on the PC, rather than the VNA. The MS46131A is well suited for confidential testing environments due to this level of security. Analysis and documentation are also simplified, as there is no need to transfer data off the onboard instrument memory.
