Question about HP8447 D and E

This is probably a stupid question, but maybe someone can assist.

I want to improve the performance of a spectrum analyzer for low level CW signals.

Can the HP8447E amplifier which is described in the literature as a 'power amplifier' be used for this?

The HP8447D is described as a pre-amplifier, but as far as I can see, the specification is almost identical apart from the gain.

Is the reference to pre amp and power amp just words - or is it fundamentally different?

Comments appreciated
