1. A sensor system for measuring an analyte concentration in a host, the sensor system comprising:

  • a sensor comprising at least one electrode;

    a receiver; and

    sensor electronics configured to measure the analyte concentration in the host when the sensor is implanted therein, wherein the sensor electronics comprise a data sampling portion in data communication with the at least one electrode, wherein the data sampling portion comprises an analog portion configured to measure the current flowing at the at least one electrode and to convert the current measurement to digital values representative of the current, wherein the digital values are acquired at a predetermined time interval, and wherein the sensor electronics comprise a transmitter portion for wirelessly transmitting a signal indicating a level of the analyte in the host at a programmable transmission interval to the receiver, wherein the programmable transmission interval is a multiple of the predetermined time interval, and wherein the programmable transmission interval is selectable by a user using a user interface of the receiver.
