  We provide an experimental framework where periodically driven PT-symmetric
systems can be investigated. The set-up, consisting of two UHF oscillators
coupled by a time-dependent capacitance, demonstrates a cascade of PT-symmetric
broken domains bounded by exceptional point degeneracies. These domains are
analyzed and understood using an equivalent Floquet frequency lattice with
local PT-symmetry. Management of these PT-phase transition domains is achieved
through the amplitude and frequency of the drive.
