Keysight Technologies M9485A VNA PXIe Multiport Vector Network Analyser

Keysight Technologies has introduced the M9485A VNA, a high-performance PXIe multiport vector network analyser designed for high-volume wireless component manufacturing of front-end modules, switches and filters used in mobile phones and base stations.

The multiport architecture provides fast measurement while maintaining high dynamic range and has a frequency coverage of 1 MHz to 9 GHz. Suitable for future component designs, users can configure the port count they need, saving money and enabling fast reconfiguration as test needs change. The product offers fast speed (5 ms at 201 points with 2-port calibration) and wide dynamic range (up to 142 dB). The VNA also delivers low trace noise (0.001 dBrms at 10 kHz IFBW) and high stability (0.005 dB/°C).

During volume manufacturing, test speed is critical and space is often limited; however, with its true multiport capability up to 24 ports, all receivers synchronise with a common source to measure all S-parameters simultaneously. When measuring multiport devices, this configuration reduces the sweep time as compared to a switch matrix-based solution.
