Testing of the Triggering Interferometric Sum Correlator and the Tunable Universal Filtering Frontend
The Antarctic Impulsive Transient Antenna (ANITA) is a balloon-borne radio experiment that is designed to detect ultra-high energy (UHE) neutrinos and cosmic rays. The fourth iteration of ANITA is currently flying and was launched on December 2, 2016 in Antarctica. ANITA 4 will fly for twenty to for...

This problem caused specific bits to be inverted or locked into a state. This in turn made the TISC not perform correctly and unusable for ANITA 4. The TUFF was assembled and modified based on tests and is currently onboard ANITA 4. The TUFF will hopefully allow ANITA 4 to obtain more data about cosmic rays and UHE neutrino interactions during its flight.
