A general purpose pulsed microwave circuit was developed for the purpose of measuring resonator Q by the pulse ring‐down method in EPR spectrometers without pulse capability. The circuit was installed and tested in a Bruker X‐band EPR bridge. This method and circuit could be adapted for use in a variety of spectrometers operating at various microwave frequencies. © 2011 Wiley Periodicals, Inc.
