The source will then be set tothe second voltage level and the 10 channels will again bescanned and measured.Since this example uses instruments that do not have TriggerLink (Model 196 and 230), the Model 8502 Trigger LinkAdapter is required. Connections are shown in Figure 4-27.For this example, the Models 196 and 230 are programmedfor External Triggering and the Model 230 is set to source thefirst voltage level. The Model 7002 is configured as follows:Model 7002:Scan List = 1!1-1!10,Arm Layer:Arm Spacing = Immediate*Arm Trigger Control = Acceptor*Arm Count = 1*Scan Layer:Scan Spacing = TrigLinkInput Line = # 2Output Line = #1Scan Trigger Control = SourceNumber of Scans = 2Channel Layer:Channel Spacing = TrigLinkTrigger Link Mode = AsynchronousInput Line = #4Output Line = #3Channel Trigger Control = Source*Number of Channels = Use Scanlist Length** Indicates that the setting is the RESET (and factory) default condition.4-64
