5.5.3 Diode
5.5.3.1 Limits
NOTE:
The diode test is described in section 10.5.
Figure 5-19 Test Step Diode, Test Properties Limits
Enable During the diode test, two measurements are performed optionally:
• Voltage Measurement
Measurement of the forward bias voltage (knee voltage)
• Current Measurement
Measurement of the reverse bias current
The related measurement is performed when the check box is select- ed. At least one measurement must be activated.

Upper Limit Lower Limit
The upper and lower limits of the measured forward bias voltage (knee voltage) can be entered in these fields. The fields on the left contain the absolute value in the same unit as the nominal value. The fields on the right contain the deviation from the nominal value as a percentage.
Inactive input fields (which appear in grey) are recalculated and dis- played with the command “Edit…Apply”.
Absolute / Relative This setting determines whether limits will be entered as absolute val-
ues or relative values.
Current Measurement
Nominal The nominal value for the reverse bias current to be measured is en-
tered in this field.

The upper and lower limits of the measured reverse bias current can be entered in these fields. The fields on the left contain the absolute value in the same unit as the nominal value. The fields on the right contain the deviation from the nominal value as a percentage. Inactive input fields (which appear in grey) are recalculated and dis- played with the command “Edit…Apply”.
