HELP!!! xferring waveform from PC to AWG

I need to know exactly what steps are necessary for transferring a
waveform file from a PC to an AWG2005 Arbitrary Waveform Generator using
only LabVIEW. I tried to read a wavefrorm from a file into the AWG but
got errors. I use LabVIEW 5.1 and employed the 488 vi's -- not the
488.2 vi's.

Someone suggested I use the IBWRTF command, but this didn't even work in
the IBIC program. The IBRDF starts to write a file to the PC from the
AWG to the path_name\file_name specified on the command line, but
encounters a time-out no matter how long I set TMO for.

Any and all suggestions greatly appreciated.

Thanks,
Mike Forkner

I used t
he AWG2005 arb a few years back with LV4.0.1 while designing a
maintenance test station. One question I have: Do you need to transfer
actual data, or can you get by with modeling the waveform parametrically?
The approach I used for each waveform was:

1. Build an equation definition locally
2. Transfer the equation definition over the GPIB to the arb mass memory
3. Compile the waveform in mass memory
4. Delete the original equation definition
5. Transfer compiled waveforms to dynamic memory as needed

This approach, if it is acceptable to your application, allows you to
eliminate waveform variability and minimizes the amount of data transferred
over the GPIB interface (which can be enormous for raw data). I remember
briefly flirting with raw data transfers, but I don't think I kept any of my
notes.

Hope this helps,
