A diagnostic to resonantly probe Alfvén Eigenmodes (AEs) has recently been upgraded as part of an international collaboration. New amplifiers drive each of 6 antennas in two toroidal locations, allowing precise control over the driven toroidal spectrum. The capability to detect and measure weakly damped modes in real time, allowing them to be tracked throughout a discharge, has been demonstrated. AEs have been detected in a range of plasma shapes and as part of dedicated TAE studies. A further upgrade is underway to allow detection of low frequency modes, such as the GAM and the BAE.
