Tool for measuring spectral noise density ?

Please could anyone suggest a piece of equipment for measuring the spectral noise density of amplifier circuits (similar to the plots in data sheets) ? I would like to measure the noise performance of circuits using low noise amplifiers (e.g. AD8610) in nV/ rtHz, over a frequency range of 1Hz to 1MHz. We currently use a HP3562A, but it does not have enough frequency range.
