Multiple VME Bus Data
Transfers
During real time data transfers, readings are taken directly from the A/D
converter and sent to the VME bus. These readings are also stored in
digitizer memory. Transferring (real time or post measurement) readings
from memory does not remove the readings from memory. As a result, a set
of readings can be transferred to the VME bus multiple times. The digitizer
is configured for an additional data transfer with the command:
VINStrument[:CONFigure]:VME:MEMory:INITiate
Reading the data register after executing this command transfers the data to
the VME bus. If a subset of the total number of readings is transferred,
execute the ABORt command following the transfer to allow for additional
transfers. The digitizer should be configured with
VINStrument[:CONFigure]:VME:MEMory:INITiate for each subsequent
data transfer.
