Agilent X-Series Signal Generators User’s Guide 235
Basic Digital Operation (Option 653/655/656/657)
Understanding Option 012 (LO In/Out for Phase Coherency) with Multiple Baseband Generator Synchronization
Figure 8-31 3x3 and 4x4 MIMO (LO In/Out for Phase Coherency) Equipment Setup
Note:
A SMA flexible cable is recommended for the input to the 4–way splitter connections to the LO IN and LO OUT of the instruments
with Option 012 (see page 232).
To optimize the phase coherence, the same length SMA flexible cable is recommended for the output of the 4–way splitter
connections to the LO IN of the instruments with Option 012 (see page 232).
To minimize synchronization delay, the Agilent BNC cable 10502A is the recommended cable for the rear panel daisy chain
