S301 - Receiver to Ports (3, 7, 11 and 15)
Switch 301 provides control of the A Receiver path to PNA Port 3 and ports 7, 11 and 15 to
the Test Set. In the state shown in the block diagram, switch 301 routes the Coupler Arm
from the PNA Port 3 to the A Receiver and all unused Test Set ports (7, 11 and 15) Coupler
Arm paths are terminated.
S401 - Receiver to Ports (4, 8, 12 and 16)
Switch 401 provides control of the B Receiver path to PNA Port 4 and ports 8, 12 and 16 to
the Test Set. In the state shown in the block diagram, switch 401 routes the Coupler Arm
from the PNA Port 4 to the B Receiver and all unused Test Set ports Coupler Arm paths
