Looking for a T&M piece of equipment, close to a pattern generator or arbitrary waveform generator.

Essentially a multiple channels (Let's say 8 - 16 channels) of digital outputs with a graphical interface to design a waveform, set amplitude, frequency, burst length, etc. Bonus if it can formulate data packets (serial, ethernet, etc.).

Basically I want something that can output all of the functions a logic analyzer could measure.

All the function generators I've seen are more limited in features from the digital front, and have only 1-2 channels.

Does this exist? How do people test their equipment? It seems like being able to source reference data for digital equipment would be a common requirement.

In my context, I'd love to be able to emulate a fancy absolute digital encoder signals (including absolute serial data in addition to incremental tracks), or incremental encoders with hall effect signals. This would require a minimum of 9 channels of parallel data. I can of course run a real encoder into the circuit, but this seems... imprecise.

I think my data logger can play back "digital" outputs. That is 32 channels.
I have a ARB that plays back two channels of analog signals. I need to find the manual, but I think in the back, the inputs to the DACs is brought out. So it outputs digital information.

I don't know of any software that will help.

This thing has 16 digital output that will do much of what you want. This one is built for analog & digital. There is one that is digital only and has more I/O. Thereare some versions that come in a metal box for more money. (faster)

Yep they exist alright !
Budget ?
Go looking here but have a chair ready for when you hear the price:
