Really good point about it being a powerful testing tool. Especially good for reverse leakage threshold degradation detection. Had a power supply with excessive heating once, everything was testing perfect until I hooked up the main transistor to the tracer. Keep up the good job!

Thanks for deciding to share that . I can imagine how much work filming a video requires. I could watch your videos all day because I know I'm gonna learn something. I've been thinking of getting a curb tracer and you have shown benifit in some older equipment. Thank you my friend !! 73

This might come in handy with the Leader tracer I bought. Thanks for the design!

I use KEITHLEY source generator four quadrant, model 2450 and 2461 together with kickstart software to work as curve tracer for my transistor BJT and mosfet. I match mosfet for high end audio amplifier. work great .

I always had thinking about this topic. And not only on transistors, but capacitors and diodes aswell.

Just as a heads-up, ST Microelectronics makes a TL072/ TL074 with a much higher slew rate of 16V / µS, which would be an increase of 23%. Thanks for this video!

Nice modification Peter, I have the same curve tracer, maybe one day I will get the chance to do the same to it, I have saved your video to watch it again later :-)

Hi Scott, the old heathkit can be very helpful in some ways, especially with a Mos Fet Mod.

Curve tracing is a forgotten art. Having taught Uni EE undergraduates over the last 20 years, I can tell you there is very little emphasis on such techniques. There is just not enough time in the curriculum!

Yes, I fully agree it is a forgotten art and sometimes very helpful. We see that no A brand test device manufacturer has one in their portfolio that is telling a lot...

For what it’s worth, I graduated BSEE in 2010 and one of our labs was to design a transistor amplifier and confirm performance based off of a curve tracer’s information. Tektronix 571. Another student developed a GPIB interface as their senior design project! How cool!

What about testing dual gate MOSFETs like the kind used as RF amps in a lot of radios? Is there any way to test them besides trying them in the circuit?

for gate 2 you use an dc voltage to preadjust and that's it

Yeah, he misspoke earlier in the video but states it correctly @15:42. He means to say that normal FET's work fine with the curve tracer, but MOSFET's do not.

Please be more concise and get to the points much faster. It is painful having to listen to so much that could have been said in a fraction of the time.
