American Amplifier Technologies has released a vector network analysis module.
The company said that the new EmPower Controller VNA brings automated feedline and antenna evaluation to its existing remote-control suite.
“The system allows engineers to assess transmission performance in real time, without interrupting on-air operations,” AAT said.
The VNA module is designed for the broadcast and RF communications industries, measuring both time- and frequency-domain characteristics. AAT said this gives engineers two complementary perspectives on the same signal path, which can help identify where changes occur along the feedline and how they affect overall system performance across the band.
Using stored references and continuous monitoring, the EmPower Controller VNA identifies variances in antenna or feedline behavior, alerting engineers before the variance results in an outage or degraded signal quality, AAT said.
Through AAT’s EmPower Mobile App, users can access visual overlays, automated comparisons and historical trends. The VNA works alongside AAT’s RF power monitoring, control modules and cloud-based analytics.
AAT is the parent company to Shively Labs and Kathrein-Scala—a manufacturer of FM, VHF and UHF antennas, filters, combiners, coax and rigid line components.
