The S4000 Series Spectrum Analyzer Frequency Extension Module is a newly developed product by Siyi Technology designed to extend the frequency range of signal and spectrum analyzers. It offers a maximum frequency coverage of up to 500 GHz (customizable) and can be interconnected with a signal/spectrum analyzer to establish a complete millimeter-wave signal and spectrum analysis system.
Once connected to the main spectrum analyzer unit via a USB cable, the extension module is automatically recognized, and parameters—such as frequency bands and conversion loss—are automatically configured. This series of frequency extension modules boasts several key advantages, including low conversion loss, high sensitivity, a high input 1 dB compression point, and excellent compatibility with host units, all of which significantly enhance testing efficiency. Furthermore, the module features a compact form factor and incorporates a “recessed” input port design, allowing for flexible adaptation to a wide variety of testing scenarios, including on-wafer testing.
