Rohde & Schwarz 2nd internal LO source, for R&S®ZNA (4 ports) external access up to 26.5 GHz requires option R&S®ZNA-B8 in addition (Hardware option)
The R&S®ZNA-B8 2nd Internal LO Source (part number 1332.4675.02) is a hardware option designed for the R&S®ZNA vector network analyzer series. This option enables external access to the second internal local oscillator (LO) for 4-port R&S®ZNA models, supporting frequencies up to 26.5 GHz. It is essential for advanced measurement configurations that require external LO access, such as mixer measurements or frequency conversion applications. The R&S®ZNA-B8 option must be installed in conjunction with compatible R&S®ZNA analyzers and is required for users who need to interface with the internal LO for specialized test setups. Installation of this option enhances the flexibility and capability of the R&S®ZNA platform for demanding RF and microwave measurement tasks.
