For more information, see data sheet.
The interface is a QSFP+ (Quad Small Form-factor Pluggable) module. It supports
max. bandwidth of up to 50 Gsample/s with optical active cables.
NOTICE! Risk of damaging the HS DIG I/Q interface.
Use active optical QSFP+ cable with max. power class 2 module (2.0 W max. power
consumption).
●
To plug in the cable:
