One embodiment includes an electrometer system. The system includes a sensor cell comprising alkali metal atoms within and an optical beam system configured to provide at least one optical beam through the sensor cell to provide a Rydberg energy state of the alkali metal atoms, the at least one optical beam exiting the sensor cell as a detection beam. The system also includes a signal generator configured to generate a radio frequency (RF) tuning signal. The system also includes a waveguide extending along a length of the sensor cell, the waveguide being configured to propagate the RF tuning signal in the sensor cell to tune at least one energy state of the alkali metal atoms relative to the Rydberg energy state. The system further includes a detection system configured to monitor the detection beam to detect an external signal based on monitoring the detection beam.
