Keysight Technologies Inc. Shared 4.8 GHz reference upgrade for the N5247B by factory

The N5247BUSR4 is a factory-installed shared 4.8 GHz reference upgrade option for the Keysight N5247B PNA-X Microwave Network Analyzer. This upgrade enables the analyzer to use a shared 4.8 GHz reference signal, which is essential for certain advanced measurement applications that require phase coherence between multiple instruments or channels. The shared reference improves measurement accuracy and stability by synchronizing the internal frequency sources of the analyzer with an external or system-wide reference. This option is specifically designed for integration at the time of original instrument manufacture and is not available as a field upgrade.
