Keysight M9318A PXIe Vector Modulator
Keysight’s M9318A is a PXIe vector modulator that is used in the creation and control of complex Radio Frequency (RF) signals. The M9318A has been designed to be a total package solution by combining a wide-band quadrature modulator and a high-speed DAC into one slot PXIe module. The Vector Modulator provides users with total electronic control of the amplitude and phase of RF signals, thus allowing users to create or manipulate complex waveforms from baseband digital data.
Operating at a wide band of frequencies from 400 MHz to 6 GHz, the Keysight M9318A provides the high degree of accuracy required for demanding test scenarios. It has a very large amplitude adjustment range of 0 to -60 dB with a resolution of .1 dB, and its phase can also be adjusted to a full 0 to 360 degrees with an equal resolution of .1 degrees. The ability to precisely adjust both amplitude and phase is important to simulate many real-world signal degradation mechanisms, determine how sensitive receivers are, and measure the performance of components under controlled, repeatable conditions. The Keysight M9318A is capable of switching signals at speeds greater than 1 ms making it well suited for Automated Test Systems where high volume throughput is desired.
In terms of application, the M9318A is an essential tool in today's communication system development and validation processes. It is commonly used for testing radar systems, satellite communication links, and 5G component analysis. The Keysight M9318A's compact PXIe format enables seamless integration into large automated test racks, providing a scalable and flexible solution for research and manufacturing environments alike. The Vector Modulator, by providing a single platform for complex signal generation and modulation, allows the engineering design and deployment of advanced wireless technologies such as base stations, aerospace, and defense systems to occur more rapidly than ever before.
