The International X-ray Observatory (IXO) has baselined a soft x-ray grating spectrometer as part of its instrument complement to provide spectral resolution (R) of >1250 over the 0.3 - 1 keV band. Current generations of reflection gratings have demonstrated R of a few hundred with very small telescopes. The same basic technology can be used with a higher resolution telescope such as IXO to provide R of up to 3000 with only small modifications. We have developed a test article which will be placed in the X-ray beamline facility at GSFC using a mirror pair developed as a technology demonstration for IXO. The test article will demonstrate the current baseline requirement for resolution. We present test data (as available) and performance predictions, as well as an approach to get to R 3000, well in excess of IXO requirements.
