2400 Series SourceMeter User's Manual
For the purposes of this test, assume the following basic sweep parameters:
Source Function: current
Sense Function: volts
Source Mode: sweep
Start Current: 1mA
Stop Current: 10mA
Step Current: 1mA
Voltage Compliance: 1V
Source Delay: 100ms
Figure 10-8 shows typical test connections for this test, and
diode curve. Note that the diode anode is connected to INPUT/OUTPUT HI, and the cath-
ode is connected to INPUT/OUTPUT LO. These connections are required to properly for-
ward bias the diode for the purposes of the test. The test connections could also be
reversed by using negative sweep voltage parameters.
