Frequently Asked Questions
Why choose 6.5 GHz coverage over standard 4.5 GHz models for C-band satellite applications?
The USG3065M's extended 6.5 GHz coverage provides complete C-band downlink testing capability (3.7-6.5 GHz) that standard 4.5 GHz models cannot match. Commercial C-band satellite systems use the full 3.7-6.5 GHz band for broadcast, VSAT, and telecommunications services, but standard 4.5 GHz generators cover only 3.7-4.2 GHz—leaving a 2.3 GHz gap in the upper C-band. This gap means incomplete LNB testing, inability to characterize wideband receivers across their full operating range, and potential need for additional test equipment or acceptance of coverage limitations. The USG3065M eliminates these compromises, enabling comprehensive testing of complete C-band receiver systems including wideband LNBs serving multiple satellites, complete downconverter frequency response validation, and end-to-end receive chain characterization without frequency gaps. For manufacturers of commercial satellite equipment serving multiple frequency segments within C-band, the complete coverage eliminates test limitations while potentially reducing total equipment costs by consolidating capability in a single instrument.
What extended frequency applications beyond satellite does the 6.5 GHz coverage enable?
Beyond complete C-band satellite coverage, the USG3065M's 6.5 GHz range addresses several emerging commercial applications. Wi-Fi 6E equipment development benefits from preliminary component testing approaching the 5.925-7.125 GHz allocation—engineers characterize filters, amplifiers, and front-end components at frequencies near the band edge before final integration and compliance testing. Telecommunications infrastructure companies testing microwave wireless backhaul receivers operating in 6-8 GHz licensed bands use the extended coverage for sensitivity and selectivity measurements. RF component manufacturers producing wideband devices for satellite, advanced wireless, and automotive radar applications benefit from complete characterization across broader operating frequencies without multiple instruments. University researchers investigating spectrum sharing between C-band satellite and Wi-Fi 6E, exploring 6G frequency allocations, or studying propagation characteristics at extended frequencies use the instrument for comprehensive measurement capability. The extended range effectively bridges the gap between standard sub-6GHz cellular/Wi-Fi test equipment and specialized microwave instrumentation, addressing a growing set of commercial applications at frequencies becoming increasingly important for next-generation wireless systems.
How does the USG3065M compare to using a 4.5 GHz generator plus additional equipment for upper C-band?
Many test laboratories historically used standard 4.5 GHz generators for lower C-band (3.7-4.2 GHz) then added frequency extension modules, additional signal generators, or simply accepted incomplete coverage for upper C-band testing. The USG3065M eliminates these compromises through continuous 9 kHz-6.5 GHz coverage in a single instrument. Compared to configurations using multiple instruments, the USG3065M reduces equipment costs (eliminating a second generator or expensive frequency extension), simplifies test setups (single instrument configuration), streamlines calibration procedures (one instrument to maintain), and improves measurement consistency (eliminating uncertainties from switching between instruments). Compared to accepting incomplete coverage, complete C-band testing capability ensures thorough validation of satellite receiver performance across all operating frequencies, identifies issues that might only appear in upper-band operation, and supports testing of wideband equipment serving multiple frequency segments. For satellite equipment manufacturers, component producers, and test laboratories, the USG3065M provides professional extended-frequency capability previously requiring multiple instruments or higher-cost specialized equipment while delivering better measurement workflow and potentially lower total cost of test.
