A signal conditioning system which includes a low voltage analog bus and a high voltage analog bus. The signal conditioning system comprises a chassis having a plurality of slots, wherein each of the slots is adapted to receive a module. The chassis includes a low voltage analog bus and adapted for transmitting low voltage electrical signals. The chassis also includes a high voltage analog bus and adapted for transmitting high voltage electrical signals. Modules may be placed in slots of the chassis, wherein each module may connect through a connector to one or both of the low voltage analog bus and the high voltage analog bus. The high voltage analog bus allows for the conditioning (including switching) of high voltage electrical signals. In an alternate embodiment, the signal conditioning system may comprise a chassis which only includes a low voltage analog bus, i.e., the chassis does not include a built-in high voltage analog bus. For example the signal conditioning system may be an existing SCXI chassis which does not include a high voltage analog bus. In this embodiment, the system may include one or more rear connectors which are adapted to connect to one or more of the modules comprised in the chassis. The one or more rear connectors collectively form a high voltage analog bus for transmitting high voltage electrical signals between the one or more modules.
