Does the diode mode of the multimeter vs Curve tracer
« on: November 07, 2024, 05:51:01 pm »
Does the diode mode of the multimeter (with the red probe on the ground) replace the curve tracer in integrated circuit testing? If not, why?

not       

a curve tracer use a scope,  that way you see the dut  specs and how it behave, and  if it leak ...   a meter will not show it like this,  on some   it help you test a zenner too


a meter will test in voltage, mostly up to 3v,  or some eevblog ones or some others who can output 15 vdc,   you get the junction voltage of a diode  0.3v 
0.6v  etc ..   can test some zenners,  but there is a limit

a meter in ohms   you may see if you are in forward or reverse   if you see conduction


as tools:  get both of them, learn on how to interpret read values,  tests them,  interference of parts in parallel on / in the circuit   etc ...

you have 2 questions here about curve tracer,  pls avoid multiples thread ....  i know it is not identical,   but be careful ...

No.

Because it doesn't show a curve on a screen.
