Hi
Yes, RDB channel archiver can store waveform data (as any other Channel Access PV data);
and users can retrieve the stored waveform data using e.g.: CSS DataBrowser (and waveform analyzer).
Answer to your 1.25GS/s requirement: If you have a HW good enough and the sampled data well partitioned into waveforms, then yes, it is possible to archive the data with use of one-or-more RDB archiver instances and with properly scaled SQL storage.
Detailed answer requires more information about how the waveforms are processed at IOC side -- in terms of their update rate, NORD, NELM, FTVL.

Hi,
I have a question to consult you.Can RDB Channel archiver engine stores the waveform data received by channel access and then get the history data back out? The waveform data presents for the voltages samples by the beamloss with sample rate 1.25Gs/s.
Any help will be appreciated and thanks in advance.
regards,
