Additionally, if the transfer configuration involves multiple digitizers,
appender digitizer readings will follow the generator digitizer readings.
Inserter digitizer readings will precede the generator digitizer readings.
Data in the packed format are left-justified, signed 2’s complement numbers
(Figure 3-8). See "Packed Reading Conversions" on page 134 for
information on converting the readings to voltages.
Multiple Local Bus
Data Transfers
During real time data transfers, readings are taken directly from the A/D
converter and sent to the Local 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 over the Local bus multiple times. The
digitizer is configured for each additional data transfer with the command:
VINStrument[:CONFigure]:LBUS:MEMory:INITiate
Also, if a measurement is aborted with the ABORt command, the digitizer
should be configured with
VINStrument[:CONFigure]:LBUS:MEMory:INITiate for each subsequent
data transfer.
Note Detailed information on the digitizers Local bus commands can be found in
Chapter 4 - "Command Reference".
