The M9485A is a multiport PXI Vector Network Analyzer from Keysight that has been designed for high-volume wireless component manufacturing of front-end modules, switches and filters used in mobile phones and base stations. It can support applications from 1 MHz to 9 GHz and provides excellent measurement speeds. This PXI VNA provides higher throughput with fewer sweeps than a VNA with a switch matrix for the same multiport device. For example, with a 24-port PXIe VNA, a 24-port device only requires 24 sweeps versus 264 sweeps with a 4-port VNA and a switch matrix. This reduces sweep time by more than 10 times, and there is no degradation in performance. The M9485A provides excellent performance with a fast speed of 5 msec at 201 points with 2-port calibration and a wide dynamic range of up to 142 dB. The VNA also delivers low trace noise (0.001-dBrms at 10 kHz IFBW) and high stability (0.005 dB/deg C). When coupled with the M9485A multiport and multi-site measurement capabilities, this level of performance helps decrease the cost of test.
