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.
