DIY Test Equipment for Audio and Ham Radio Enthusiasts:
Erno Borbely described drew a schematic for a JFET tester in his 1999 2-part Audio Amateur series "JFET's The New Frontier".  I thought it would be interesting and time-saving to incorporate his idea into a Visual Basic Project which would test for Idss, PinchOff Voltage and Transconductance.  The tester is deployed through a Measurement Computing PMD1208LS Data Acquisition Card.  The software can be downloaded as a ZipFile by clicking here -->>>  JFET Tester
