Agilent / HP / Keysight 4280A

This unit measures the capacitance and conductance of semiconductor devices and materials as functions of applied voltage (C-V) or time (C-T).

It's internal DC bias source has a range of 0 to ±100V with 1mV resolution.

This can provide measurement intervals as short as 10µS with external pulse generator (sold separately).

It measures capacitance up to 1.900nF and offers resolutions to 0.001pF.

Also, internal 1MHz test frequency provided.
