Millimeter-wave Module Cable Connections

Before connecting the millimeter-wave modules, verify that the test set and the
power supplies (if used) are powered down.
There are four RF cables for each T/R module. Cables provided with the VDI
modules are pre-labeled. The cables for use with the OML modules come in
two types, two lighter and two heavier. Use the lighter cables for the IF signals
and the heavier cables for the RF and LO signals.
