Broadband Vector Network Analyzer in Single Coax Connection

Mon, 08/03/2009 - 11:41am
Anritsu Company introduces the VectorStar Broadband ME7828A vector network analyzer system that produces industry-best dynamic range, measurement speed, and calibration and measurement stability over the broad frequency range of 70 kHz to 110 GHz. The performance and frequency coverage provide designers and manufacturers of microwave/millimeter wave components and devices with a single system to accurately and quickly measure devices from DC to daylight. Traditionally, users have been constrained by the poor performance of microwave VNAs below 500 MHz, as signal-to-noise ratio diminishes below 500 MHz due to microwave coupler roll-off. The result has been a significant weakness in device models at the low end. Previously, the only solution was to re-measure the device on a separate low-frequency system that has resulted in large concatenation errors. Due to VectorStar’s 70 kHz low-end frequency, it is possible to accurately measure devices starting at 70 kHz for DC information and up to 110 GHz for capturing all the performance of the device at multiple fundamental harmonics.
