The US Army Research Laboratory ARL has designed and build a one-of-a-kind electric-field sensor characterization facility. The unique facility features a large parallel plate capacitor with guard rings to control fringing fields, controlled by a custom LabVIEW program and several pieces of test hardware with less than 0.6 combined measurement error. ARLs electric-field characterization facility creates an approximately 1-m3 region with better than 1.5 electric-field uniformity in a smaller physical system than that described in the Institute of Electrical and Electronics Engineers Standard 1308-1994. The custom-developed LabVIEW code thoroughly tests the frequency response, linearity, total harmonic distortion, and noise across a 60-dB frequency range of an electric-field sensor in less than 10 min. The instrumentation, calibration, and characterization methods are detailed.
