Comments 1. GENerator Digitizer Configuration. Channel 1 of the GENerator
digitizer is CONFigured for 10 readings on the 5V range.
Before setting the digitizer’s Local bus configuration, the Local bus chip is
reset. Next, the Local bus mode is set to GENerate and the feed (data
source) is set to MEMory:CHANnel1.
2. APPender Digitizer Configuration. Channel 1 of the APPender
digitizer is CONFigured for 10 readings on the 5V range.
For all digitizer’s doing Local bus transfers, the Local bus chip must be
reset first. Next, the Local bus mode is set to APPend and the feed (data
source) is set to MEMory:CHANnel1.
3. Pre- and Post-Arm Readings. When the Local bus data source is
MEMory: ..., the readings are transferred over the Local bus from digitizer
memory rather than directly from the A/D. In this case, pre- and post-arm
readings are allowed prior to the Local bus transfer.
4. Initiating the Digitizers. After the memory card is configured, the card
is INITiated first so that it is ready to receive the digitizer readings. In a
configuration with multiple digitizers in the APPend mode, the APPender
digitizer(s) is (are) INITiated next. Because CONFigure sets the arm source
to IMMediate, INITiating the (APPender) digitizer causes it to take its
readings. After the APPender is INITiated the GENerator digitizer is
INITiated. *OPC? is used to allow the GENerator readings to complete and
be transferred before they are retrieved from the memory card.
Note that the APPender digitizers must have finished taking data before the
GENerator is finished. All APPenders must be ready to pipeline the
GENerator’s data at the time the data is sent.
