In order to realize laser frequency stabilization, the global evolution of an analyzer angle on the electrodeless-discharge-vapor-lamp-based excited-state Faraday anomalous dispersion optical filter (LESFADOF) with a single transmission peak operating on the Rb1529 nm (5P(3/2)-4D(5/2)) is presented. We find that the transmission of the line center peak at -80A degrees arrives at 14% in a 3 cm length lamp contained natural Rb mixed with 2 torr Xe buffer gas operating at 250A degrees C with 176 MHz radio frequency. When it is used to realize laser frequency stabilization, the LESFADOF at near -80A degrees is appropriate. Whether a single transmission peak or double transmission peaks depend on the rf voltage when two polarizers are crossed.
