I have here a quite new E4990A Impedance Analyzer that I want to use for semiconductor device characterization measurements. There are a few things I do not understand:
- What is the "Constant Mode"? I do not find much information about it, neither in the manual nor on the internet. For bias sweeps, the timing is changed depending on whether this mode is ON or OFF.
- Is there a possibility to exactly fix the timing of bias sweeps independent on the used frequency? I mean, can the time per bias measurement point be fixed?
- Can I perform consecutive up and down bias sweeps meaning that there is no voltage drop in between? Example: Sweep from -10V to 10V, maybe stay a short period of time at 10V (ideally not the case), then sweep back to -10V
I would really appreciate your help.
