Rohde & Schwarz Source reference signal access for port 1 and port 3 before the source step attenuator, for R&S®ZNA26 requires R&S®ZNA26-B16/-B21/-B23 (Hardware option, Upgrade option)
The Source reference signal access for port 1 and port 3 before the source step attenuator (1332.6184.53) is a hardware upgrade option for the R&S®ZNA26 vector network analyzer. This option enables direct access to the reference signal at ports 1 and 3 prior to the source step attenuator, facilitating advanced measurement configurations and external signal routing. It is specifically designed for use with the R&S®ZNA26 and requires one of the following hardware options to be installed: R&S®ZNA26-B16, R&S®ZNA26-B21, or R&S®ZNA26-B23. This upgrade enhances the flexibility and capability of the R&S®ZNA26 for demanding test setups in research and development environments.
