We present an analysis of the Galactic bulge emission observed by the RXTE/PCA during a set of scans over the Galactic Center field, performed in 1999–2001. The total exposure time of these observations is close to 700 ks. We construct the distribution of Galactic ridge emission intensity and spectral parameters up to Galactic latitudes . We show that the intensity distribution of the ridge emission at could be well described by an exponential model with e-folding width . Best-fit spectral parameters do not show statistically significant changes over Galactic latitude.
