- Kondensatoren >
- Keramik-Vielschichtkondensatoren (MLCC)
A. The HP4291A parameter settings:
- Measurement capacitance: PRL(Cp)
- Format : Log Y-Axis
- OSC level : 500mV
- Trigger : Continues
- Sweep Type : Log
- SRC : Freq
- Point Average : on
- Point Average Factor : 32
- Seep Average Factor : off
- Number of Points (NOP) : depending on the span of frequency
- Short Inductance : depending on the dimension of the device under test (DUT)
