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.
