The Keysight M9484CU-M9484CF-777 is an official factory upgrade option for the M9484C VXG vector signal generator. This upgrade enables one channel of the M9484C to be enhanced with the low phase noise (ST6) feature, which significantly improves phase noise performance for demanding applications such as advanced wireless communications, radar, and aerospace/defense testing. The ST6 option provides ultra-low phase noise capability, allowing for more accurate and reliable signal generation in scenarios where signal purity is critical. This upgrade is performed by Keysight and is intended for users who require the highest signal fidelity from their M9484C instrument. The upgrade is compatible only with the specified M9484C hardware and must be installed by Keysight service personnel.
