Since this example uses an instrument that does not have
Trigger Link (Model 230), the Model 8502 Trigger Link
Adapter is required. Connections are shown in Figure 2-24.
For this example, the Model 230 is programmed for External
Triggering and is set to source the first voltage level. The
Models 2002 and 7001/7002 are configured as follows:
Model 2002:
Idle state:
Bench reset = :INIT:CONT ON*
Arm layer:
Arm source = Immediate*
Arm count = 1*
Arm trigger control = Acceptor*
Scan layer:
Scan source = Immediate*
Scan count = Infinite*
Scan trigger control = Acceptor*
Measure layer:
Measure source = TrigLink
Trigger link mode = Asynchronous
Input line = #3
Output line = #4
Measure count = 20
Measure trigger control = Acceptor*
* Indicates that the setting is the BENCH RESET (and factory) default con-
dition.

Model 7001 or 7002:
Idle state:
Reset = :INIT:CONT OFF*
Scan list = 1!1-1!10,
Arm layer:
Arm spacing = Immediate*
Arm count = 1*
Arm trigger control = Acceptor*
Scan layer:
Scan spacing = TrigLink
Trigger link mode = Asynchronous
Input line = #2
Output line = #1
Number of scans = 2
Scan trigger control = Source
Channel layer:
Channel spacing = TrigLink
Trigger link mode = Asynchronous
Input line = #4
Output line = #3
Number of channels = 20
Channel trigger control = Source*
* Indicates that the setting is the RESET (and factory) default condition.
Notice that the Model 2002 is reset to BENCH defaults. With
this selection, the multimeter stays armed. Since the arm
source and scan source are set to Immediate, the Model 2002
waits in the measure layer for a trigger.
