Rohde & Schwarz Direct source monitor access for port 1 before the source step attenuator for R&S®ZNA67 (Hardware option, requires R&S®ZNA67-B16 and R&S®ZNA67-B21) (B-option ex factory only, ZNAxx-Uxxx for retrofit: ZNAxx-U161 retrofit for 2-port ZNA only. ZNAxx-U163...
The Direct source monitor access for port 1 before the source step attenuator (hardware option, part number 1332.5113.51) is an official factory-installed B-option for the R&S®ZNA67 vector network analyzer. This option enables direct access to the source signal at port 1 prior to the step attenuator, allowing for precise signal monitoring and measurement flexibility. It is designed to support advanced measurement scenarios where unattenuated source signals are required for analysis or calibration. The option requires the presence of R&S®ZNA67-B16 and R&S®ZNA67-B21 hardware options and is only available as a factory-installed feature (B-option ex factory only). For retrofit scenarios, corresponding retrofit kits (ZNAxx-U161 for 2-port ZNA, ZNAxx-U163 for 4-port ZNA) are available. This option enhances the versatility of the R&S®ZNA67 by providing direct source access, which is essential for certain high-precision measurement applications.
