[R-390] Audio Signal Generator question

Thu, 29 Aug 2002 13:34:03 -0400

The "CD" has a balanced, 600 ohm output. The "A" does not. VERY late
versions of the "CD" were also very low distortion. This series of HP
generators was manufactured for decades, and were very stable and reliable.
Suggest that you obtain the correct service / owners manual. Make sure that
the manual that you get matches the serial number of your unit, as there
were many mods made over the production lifetime of these units.

>An HP200CD followed me home from the local hamfest recently.  I figured it
was worth $15 since it was working (plus it matches my HP410B).  It is a
200CD model.  Last night someone was advertising a 200AB on Ebay (a very
nice-looking one at that).  Is the CD a later version of the AB?  Is that
only difference?  Anyone?
