Model 6485 Picoammeter Instruction Manual Triggering 7-13
External trigger example
In a simple test system you may want to close a switching channel and measure the current
from a DUT connected to that channel. Such a test system is shown in Figure 7-7, which
uses a Model 6485 to measure 10 DUTs switched by a Model 7158 low current card in a
Model 7001 or 7002 switch system.
