jfet-test (attachment to a voltmeter to measure the parameters of jfet)

To determine the parameters of field transistors with a P-N-transition on the gate, both N-channel and P-channels, will help the described above simple and inexpensive prefix to the voltmeter, which allows you to measure the initial flow of the field of the field transistor and its cut-off voltage. Thus, using only this console bundled with some voltmeter, you can, for example, select transistors with the best characteristics or select a pair of the same transistor parameters. In addition, the prefix allows you to check the field transistor for performance, to approximately define the steering transistor in the intended working point, and students and novice radio amateurs are to explore the field transistor to better understand its principle of operation.
