720 MHz Pulse EPR Imager with Arbitrary Waveform Generator-Based Bridge and Direct Sampling


A pulse 720 MHz EPR imager with a permanent magnet, arbitrary waveform generator based excitation, and detection system operating in the direct sampling and signal down-conversion modes is presented. This flexible instrument allowed testing various acquisition modes and demonstrating its signal to noise ratio advantage over the previously used 250 MHz instrument.
