dimitri Posted May 16, 2021 Share Posted May 16, 2021 (edited) Hello, How to set bipolar Vrg, say, from -3V to 1V for n-ch JFET/ depletion mode MOSFET? How to set bipolar Vrd for testing ac SSR? Is it possible to check optocouplers: LED and photodiode/phototransistor ? Maybe optocouplers with photovoltaic output? Yes, I can make my own tracer, following this approach: but for educational purposes I prefer to show digilent app. Thank you Edited May 16, 2021 by dimitri Link to comment Share on other sites More sharing options...
0 attila Posted May 17, 2021 Share Posted May 17, 2021 Hi @dimitri Unfortunately there is no bipolar option in the Tracer tool. Link to comment Share on other sites More sharing options...

0 attila Posted May 24, 2021 Share Posted May 24, 2021 Hi @dimitri The Transistor Tester Adapter was intended to use +5V or -5V rail as emitter/source to have unipolar 10V range. The next software version will let you use bipolar voltages and adjust rails with Adapter. Link to comment Share on other sites More sharing options...
0 D. Dufresne Posted March 4, 2022 Share Posted March 4, 2022 Thanks, I also need to test JFETs and depletion MOSFETs. I will wait for the next version of Waveforms. Link to comment Share on other sites More sharing options...
0 attila Posted March 5, 2022 Share Posted March 5, 2022 Hi @D. Dufresne The bipolar option was added long time ago, shortly after this post, since WF v3.16.28 Under Options adjust the Emitter option away from +/-5V. With +/-5V you have 0 to +/-10V test range, with +/-1V +/-4V to +/-6V ... You can use the public or latest beta version: Link to comment Share on other sites More sharing options...
