Here's a link to using a AWG and DSO for a crude curve tracer we did awhile back. https://www.eevblog.com/forum/testgear/fooln-around-with-dso-awg/msg4421209/#msg4421209 Another link to a Curve Tracer concept for a more advanced Curve Tracer, we are way delinquent in finishing this project as other work took a precedent. https://www.eevblog.com/forum/projects/dso-awg-based-curve-tracer/ Best |

Here is my expedient. My AFG has a max of 10 volts which means low voltage zeners only. But it should work for most of us amateurs. Over time I may add an amplifier. My Kikusui cannot even really pick up the knee. But the venerable Siglent 1104XE can. I took photos instead of screen shots to better show the setup. Also,as noteself and a breadcrumb, the hi current output is 13.3 X the low output. This makes little sense to me at the moment. I will change the 7.5K resistors to 10K for a useable 10X scale. |
