It's non-green blasphemy, but here's an option of you can't find a AG-8...

The HP 200CD or 200CDR (rack mount version) will do what you want with
ease. I've seen them for $20-50 at hamfests.  Surplus dealers like C&H in
Pasadena Calif. get a little more.  Plan on replacing the power cord,
however, the plastic formulation that HP used crumbles when it gets old.
I used a saber saw and a file on mine and installed an IEC socket/RF
filter from a junk PC power supply.  Looks like it was made that way.
While I had the case off I also added a BNC jack on the front for
my counter (Heath, of course).  I wired it to the point before the
attenuator and added a voltage divider made of metal film resistors
so that the BNC jack has a 1v p-p signal.

No, I didn't butcher a rare unit - the HP 200CD is a very very common on
the surplus markets.

Mike
