The WBIQ has a wide IF bandwidth that cannot be processed by the on-board Analog-to-digital converter. The WBIQ product is intended for use with external digitizers only and it interfaces with such devices across the analog IF output. It cannot produce a wideband digitized output over the Ethernet port.
There is only one mode that can be used through onboard digitizer for the WBIQ option model, which is SHN mode. In this case, it is over the Giga Ethernet port.
If the customer is using SHN mode with an onboard digitizer for their application, then there is no point to use WBIQ. SHN mode is often used as a reference in WBIQ option.
