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,
