I need a driver for HP4280A 1MHz C Meter/C-V Plotter

Recommended Posts

Hi everybody,


I am working on electrical characterization of Semiconductor Devices. I am using the HP 4280A C-V Plotter for that reason.


I have just developed a program that control the instrument just in C Mode. the C-V and C-t Modes doesn't work enough and I found errors in reading the data (the data recorded is only the first one).

open the "HP 4280A C-V Mode.vi" example.

Please help me as soon as possible.


Thank You in Advance.

Best Regards.
