To throw in my $0.02 worth:

I have the DVM option on a couple of my counters, but never pay much 
attention to it.  I have DMMs and a couple of Simpson 260s.  However, 
the discussion made me curious so I checked on what they do.  Two things 
of interest:
- They only measure DC. (The ones I have).
- The one in the 5328A will also "Read A" or "Read B".  This reads the 
level of the trigger voltage (DC).  The catalog says this is really 
helpful for setup.  I'll have to give it a try sometime.
- Others are just a separate input and don't measure anything on the AC 
input signal.

On the topic of suffix letters: Sometimes the suffix letter indicates a 
variation in the basic model.  For example, the 3336 synthesizer/level 
- 3336A - CCITT version
- 3336B - Bell system version
- 3336C - General purpose version.
