87050A Option K24 Theory of Operation

Each path is routed to a bank of four 1 × 6 switches, for a total of eight 1 × 6 switches. Each

bank of switches is routed to a single 1 × 4 switch where it becomes either the

Transmission or Reflection port.

All switches are mechanical, biased according to the necessary switching path. A user

interface through the GPIB and parallel ports converts the necessary input signals from

the user to the necessary control signals to control the switching paths.
