The cutoff voltage of a p-channel JFET
To determine the cutoff voltage of a p- channel JFET:
1 Connect the red input probe lead to the drain.
2 Connect the black input probe lead to the source.
3 Connect the red output alligator lead to the gate terminal
through a 100 kΩ resistor, and connect the black output
alligator lead to the black input probe lead.
4 Gradually decrease the voltage output from +00.000 V to
+15.000 V. The R
(Figure 5- 12 on page 107).
5 Observe at what point the resistance reading becomes OL;
the voltage bias level at that point would be the cutoff
voltage for the p- channel JFET.
