This is an Octopus curve tracer circuit.  It has been around since the 1930's.  The blue output is the Y axis which represents current and the green is the X axis which represents voltage.   If you put an oscilloscope in XY mode and connect blue to Y and green to X you should see a a diode curve with the diode that is in the circuit under test.  I have a Tektronix 475 so I have built myself a curve tracer and verified that it works.

I had X and Y switched so I had to correct it!

Changed the component under test to a diode.

Thanks. This is awesome! Done octopus with Rigol but its too noisy even with x10 probes.
