I also prefer the H-P analyzers, but the Tek 9100 DAS has one nice feature,
the pattern generator option. It will generate fairly complex streams of
16-bit words up to 25MHz (40ns/word). The patterns can have multi-level
subroutines, jumps, conditional jumps, and even (*yes*) interrupts.

I used it to generate (using only one bit of 16) Ethernet packets (to debug
a PLL), hand-crafting the Manchester coding by running the pattern generator
at 20MHz.  It worked fine. (The subroutine feature came in REAL handy!)

But then again, we just happened to have one I could use. I wouldn't buy
it for that reason alone (I would kludge up a RAM and a counter).
