E4402B - RBW cannot be reduced.

I cannot reduce the RBW of my E4402B below 1 kHz (with a span of 150 kHz and center frequency of 1.24 MHz)  It experienced a memory reset and the firmware was reloaded last year and I guess this is the first time I have tried to use a lower RBW since that all happened.  It has shipped with options 1AX, 1DN and 1DR.  It would seem I may have lost option 1DR (the tracking generator appears to be working fine).  What do I need to do to get the enhanced RBW option working again?  S/N is MY41441731.
