Keysight Technologies AXIe and PXI Modular Test Solution for Multiband SATCOM Monitoring Application Note Introduction Today's satellite systems are required to deliver more complex data streams to and from terrestrial stations than ever. The process of monitoring such massive multiband, multi-frequency satellite data streams becomes a multifaceted and challenging environment. Present monitoring configurations usually consist of a dedicated test set allocated to a specific band or frequency. For many satellite earth stations that means a room full of fixed hardware and the resources to support it. Going forward, a solution that consolidates multiple pieces of hardware into a single unit, whenever possible, has the potential to reduce size, conserve resources and insure that the five-nines level of data reliability is maintained. Evolving measurement solutions should be multifunctional across multiple bands and technologies, and be integrated into as compact a footprint as possible. In this application overview, the challenge of monitoring multiple 1.2 GHz satellite bands, from UHF through Ka, and multiple modulation schemes is addressed. The proposed solution replaces individual test units with the smaller PXIe and AXIe modular platform and the Keysight Technologies, Inc. 89601B Vector Signal Analysis (VSA) software. Figure 1: Key components of the solution are the M9703A AXIe high-speed digitizer, M9362A downconverter, M9352A IF amplifier and the N5183A LO source.
