This contribution describes the current state of the X-band EPR setup at the Novosibirsk Free Electron Laser facility (NovoFEL). Recent advances in experimental hardware and software are discussed in detail. Improvements include implementations of fast detectors for recording the THz macropulses during experiment, possibility of simultaneous use of two oscilloscopes, configured at different timescale, and the development of software for on-the-fly data treatment. Modification of hardware and software of the EPR spectroscopy station at NovoFEL facility was funded by the Russian Science Foundation, grant number 17-13-01412. Synthesis of [Co0.01Zn0.99(piv)2(2-NH2-Py)2] complex was funded by IGIC RAS state assignment.
