The circuit shown enables dynamic diode testing with an oscilloscope. We found this configuration in a 1980s documentation. The external signal source may be a small transformer. To calibrate use a resistor instead of a test diode.
This circuit can be used as a shield for microcontrollers. The circuit is from American...
