The Keysight M9803A is a PXIe Vector Network Analyzer delivering multiport measurement capability across 9 kHz to 14 GHz with up to 142 dB dynamic range. This modular platform supports 2-port, 4-port, and 6-port configurations, each with fully synchronous test ports for simultaneous multiport measurements and multiport error correction. Engineers can cascade modules within a single PXIe chassis to achieve up to 50 ports for complex multisite test requirements.
