External triggering with BNC connections
An adapter cable is available to connect the micro-DIN Trigger Link of the Model 2182 to
instruments with BNC trigger connections. The Model 8503 DIN to BNC Trigger Cable has a
micro-DIN connector at one end and two BNC connectors at the other end. The BNC cables are
labeled VMC (trigger line 1) and EXT TRIG (trigger line 2).
Figure 7-9 shows how a Keithley Model 220 Current Source can be connected to the Trigger
Link of the Model 2182 using the adapter cable. When used with the STEP mode of the
Model 220, you can perform synchronized source-measure operations without the use of a
computer. Whenever the Model 220 receives a trigger from the Model 2182, it will step to the
next current source value.

NOTE If the Model 2182 trigger line configuration has been changed from the factory
setting, the Model 8502 Trigger Link Adapter must be used to interface with
instruments having BNC trigger connections. It has two micro-DIN connectors and
six BNC connectors, one for each trigger line.
