Their no polarity inverter circuit,
The PNP measure diagram is below

If test PNP, System will set Eout to 36V,
And step down the Bout inorder to generate Ib.
System measure the Vrb,Vrc and calculate the Ic and Ib and Hfe.

The Vrb Vrc measure circuit is below

It use a OP07 as follower, The op07 bias current and offset current will have some voltage drop on RB. But Op07 bias current and offset current less 5nA,and Op07 offset voltage is less 1mV,so OP07 only a little affect to DTU base current.

 13th July 2012, 08:47 AM #255 Banned   Join Date: Dec 2007 Hi locky_Z Maybe this has been posted before IS there a manual for the calibration of the curve tracer? And maybe, more important, a way to return the curve tracer to original calibration if things go wrong?
