I developed an ADC model-specific custom record (supported hardware config/monitor and metadata to construct scaled waveform). I wrote a CA client program to assemble amplitude/units/time scaled waveform using the custom record and raw waveform. This program also converted the resultant waveform and metadata for non-EPICS data repository.
This was in 1999. I have long had plans to eliminate the client program.

Dear all
We have a question about implementing device support for an ADC that returns values in a waveform record, not using asyn.
If we want the data to be converted from the ADC voltage range into user's engineering data, we need engineering limits or scaling factors or...
Seems that waveform is not as detailed as ai for that.
I guess that we are not the only one in the globe having this issue.
I'll appreciate to have some indication on the implementation.
Thanks!
