Patent ID: 7764958

Claim:
A measurement system, comprising: sensors; a network of wireless sensor nodes, wherein at least one of said sensors is connected to each said wireless sensor node, wherein each said wireless sensor node includes a node transceiver configured to transmit digital data derived from said at least one sensor; and a base station configured to receive transmitted digital data from a plurality of said wireless sensor nodes of said network of wireless sensor nodes, determine whether there is an error, convert to analog, provide an analog output, and provide an output indicating whether an error was found, said base station including: a base station transceiver configured to receive transmitted digital data from at least one wireless sensor node of said network of wireless sensor nodes and to provide at least one received digital signal derived from said transmitted digital data; a processor configured to analyze said at least one received digital signal for detecting an error; digital to analog circuitry configured for converting said at least one received digital signal into at least one received analog signal; a first analog output connected to provide an analog output signal derived from said at least one received analog signal; and a second output connected to provide an output signal indicating presence of an error in said received digital signal.
