Electric field double probes are used on many satellite missions to provide accurate AC and DC electric field measurements. These measurements are vital in extracting quantities that allow for a full understanding of the plasma environment these satellites fly through. It has been found however, that these electric field measurements can have anomalous signatures that have so far gone unexplained. Our aim is to investigate these signatures by using the space plasma simulation chamber at the Naval Research Lab and try to replicate the signatures found in space. Current work is being made on the hardware to run these tests, but the first round of testing should be concluded at the end of Summer 2023. In this project we purpose a possible cause for why these signatures arise and discuss ongoing work toward validating this theory.
