Remote programmable reference systems and methods are described. A remote programmable reference system maintains a set of parameters from which a reference signal can be generated to transmit the reference signal to a system platform. In an embodiment, a parameters update can be received from which a modified reference signal can be generated to transmit the modified reference signal. In another embodiment, the remote programmable reference system maintains multiple sets of parameters from which respective reference signals can be generated for any one or more system platforms having different system configurations. The system platforms can interface with the remote programmable reference system through a system interface via a communication network.
