The sampling rate for those waveforms is 45 MSa/s with bandwidth 20 MHz. They can be played on the Keysight signal generators like X-Series SG (MXG, EXG, CXG), ESG and PSG. The zip file on this page includes three demo waveforms as the interference signals for adaptive test defined in ETSI EN 301 893.
