The region of the Hubble Deep Field North was observed by the Chandra X-ray Observatory for a total of 227 ks. Over 200 sources were detected in this observation. The number of sources versus their intensity will be presented as well as spectral information for the sum of the sources. A comparison to the current best estimate of the Diffuse X-ray Background will be discussed.
