Yup a 576 be nice but there is an alternative ... If one need to measure hi current output devices
The DCA Pro is really nice clever gadget only snag for me is that it does not recognise Jfet pins
It beats the old 75 as no more really expensive batteries that is enough to justify the upgrade

Willing to share this time ?
If you show me yours I show you mine
One may goggle up Zhoufang (is that right?) curve tracer
Not sure if that's aimed at me but the ones I use are not curve tracers, just quickly knocked up on vero board and measure at one current only. That being the current at which I will operate the device at in the intended circuit. Being a manufacturer and wanting to earn a living from this () no I do not share anything really interesting/original/of use to rivals... as one would expect!

WP_20170825_19_43_58_Pro.jpgWell then I am not going to show you this one
For all the nice peoples that do this for passion or just to stay out of troubles
A constant temperature (50C) rig to measure up Moss Fets
Set up the pot (gate voltage ) to get a wanted current flowing through source and drain
A further Mossfet is used to warm up the plate and the Fan (CPU cooler)speed is regulated by a thermistor
My DCA75 pro also just arrived, very nice
Ill have to dig out my bags of transistors and start testing again, I seem to remember hfe of 415 was the match I got for my first build but it took a few thousand transistors to achieve that
