External triggering with BNC connections
An adapter cable is available to connect the micro-DIN Trigger Link of the Model 2000 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 3-9 shows how a Keithley Model 706 Scanner can be connected to the Trigger Link
of the Model 2000 using the adapter cable. With this adapter, a Model 706 could be substituted
for the Model 7001/7002 in the previous example. With the Model 706 set for External Trigger-
ing, the test would start when the single scan mode is selected and initiated.
If the Model 2000 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 trig-
ger connections. It has two micro-DIN connectors and six BNC connectors, one for each trigger
line.
