X-Band pulsed EPR spectrometer designed and constructed in Wroclaw UT is described. The spectrometer has been designed as a modular system which makes it easy to upgrade. In the microwave path a power pulse amplifier with traveling wave tube (P/sub out/=350 W) is used. Pulse EPR signals are recorded with a fast digital storage oscilloscope of LeCroy (9361, 2.5 GS/s), supported with hardware mathematical option (WP02) performing FFT calculations. The system is fully controlled with PC computer via a GPIB interface.
