Spectrum Analyzer Bandwidth Measurement

Dear Sir:

       I would like to set my 8593E spectrum analyzer (SA) center frequency at a fixed frequency.   I do not want this frequency to change when I change the frequency SPAN settings.    The internal automatic coupling operations, internal to the SA, auto sets the center frequency when I change the frequency SPAN settings.   

       Can anyone please show me a simple method to fix the center frequency and then make display monitor adjustments without altering the center frequency? 

       In order to explicitly answer this question, let me offer an example measurement requirement.  Let's say I want to look at a signal at 2 GHz (center frequency = 2 GHz) and observe a display frequency span of 10KHz to 3.999990 GHz.   Can you tell me the buttons which need to be pressed to accomplish this task? 

       Thank you for your time.
