RF Configuration
Model: MP-2U18S-30-GPIB
Four normally open SP10T switches (Dow-Key part number: 5A1-520802N-ROHS)
mounted on the rear panel.
The switches are interconnected in a 1x30 multiplexing configuration as shown
below.
N.C. = Not Connected
These ports are not connected as part of the 1x30 configuration, but are working ports.
So this matrix could be considered a 1x37 configuration (although 7 ports will have
lower insertion loss then the remaining 30 ports).
Note that all switches are bi-directional. Hence each RF port can be considered an input
or an output.
Note that all interconnection cables have the same length for the purpose of keeping the
RF performance (insertion loss) the same among all paths.
The cables have been installed as part of our final test procedure, but then un-installed
to avoid damage during shipment of the matrix.
