Rohde & Schwarz Direct source and receiver access for R&S®ZNA50 (4 ports) (B-option ex factory only, ZNAxx-Uxx for retrofit) (Hardware option)
The Direct source and receiver access for R&S®ZNA50 (4 ports), part number 1332.4581.54, is a hardware option designed specifically for the R&S®ZNA50 vector network analyzer. This option enables direct access to the internal sources and receivers of the instrument, allowing advanced measurement configurations and enhanced flexibility for demanding test setups. It is available as a B-option ex factory only, meaning it must be specified at the time of order and cannot be retrofitted in the field (for retrofit, the ZNAxx-Uxx option is required). This feature is particularly useful for users who require direct signal routing for calibration, custom measurement paths, or integration with external test systems. The option is compatible exclusively with the 4-port configuration of the R&S®ZNA50.
