Shifu,

We had a driver done by Richard Dabney at LANL (he's no longer there) for the Joerger VME AFG in 2003. If that is useful I can dig up the code (VxWorks only and Epics 13, not 14).

Dear All,

The arbitary function generator VME-4145 we are using is discontinued and the replacement is not available now. We could buy some  if you have more spare parts or have some parts lying around.

Basically, the requirements for the arbitary function generator is as
follows:
 > 33 millisecond long programmable waveform triggered at 30 Hz  > bipolar output  > 10 usec time resolution (or better) (implies a memory length of > 3.3K)  > 1% amplitude resolution (or better) (e.g. 10-12 bits would be fine)

It would also be great if you could recommand some modules with EPICS device driver which can meet the above requirements.

Any answers and suggestions would be greatly appreciated.

Shifu Xu
