Keysight/Agilent M9803A PXIe Vector Network Analyzer
The Keysight M9803A provides complete two-port vector network analysis for frequencies from 9 kHz through 14 GHz in a compact, single-slot PXIe module. It features a dynamic range of 140 dB, a measurement time of 2 ms per point (for a 201-point sweep), and trace noise of less than or equal to 0.0015 dB RMS. Together these enable accurate S-parameter characterization to be included directly in automated testing platforms. As it is typically stable against changes in temperature by a factor of 0.005 dB/C, the M9803A will provide consistent results regardless of the environment being tested. In addition, at maximum output levels (typically 10 dBm), the device is capable of driving DUTs without additional external amplification. These characteristics have made this product ideal for use in the study of signal integrity, in measuring unbalanced signals, and in evaluating the performance of components such as coaxial cables, antennas, filters, connectors, isolators, amplifiers, and mixers.
The M9803A was designed to support scalable multiport applications. A single M9803A may operate independently as a two-port analyzer, or multiple units can be synchronized together inside a PXIe chassis to create a true multiport VNA capable of measuring up to 50 ports. Because all of the test ports are fully synchronized during operation, users can perform simultaneous multiport measurements without having to compromise on switching times. The design of the M9803A also enables users to access a wide variety of measurement application suites that extend far beyond standard vector network analysis and include spectrum analysis and pulsed-RF measurement. As such, engineers are able to evaluate frequency converters and other active devices under simulated operating conditions (i.e., modulated signals) directly on the same hardware platform used for vector network analysis.
Like most of Keysight's benchtop PNA, ENA, and USB VNAs, the M9803A shares the same measurement technology. As a result, all models share a common software base, which guarantees that measurement results will correlate exactly and that the programming interface will be identical for all instruments. This simplifies program development efforts, as the need to migrate programs between R&D and production environments is greatly reduced. By allowing precision vector network analysis to be integrated into a standard PXIe module, the Keysight M9803A reduces rack space requirements for testers, decreases cabling complexity, and increases test throughput in various areas, including semiconductor characterization, high-volume component inspection, and wireless infrastructure manufacturing.
