Rohde & Schwarz Extended power range down to -80dBm, for R&S®ZNB8 2-port (retrofittable in factory or service only)
The Extended power range down to -80 dBm option (part number 1316.0227.02) for the R&S®ZNB8 2-port vector network analyzer enables measurements at extremely low power levels, expanding the instruments dynamic range and sensitivity. This option is retrofittable in the factory or by authorized service only and is designed to support applications requiring precise characterization of highly sensitive devices or components. By extending the lower power limit to -80 dBm, users can perform accurate S-parameter measurements on devices with very low input power tolerances, such as low-noise amplifiers or sensitive receivers. This enhancement maintains the high measurement accuracy and stability characteristic of the R&S®ZNB8 series.
