The HP 33120A goes up to 15MHz, and can be uploaded with data to make 
any arbitrary waveshape you can imagine.  If it doesn't come with it, 
a small customer-installable upgrade board can be added to lock to an 
external reference.  The 33220A is the current model, which runs up 
to 20MHz.  They come in the same portable case design as the 
53131A/32A.  They are not likely to be bargain-basement prices, but 
do appear on ebay from time to time.
