Option 001 provides a device guide for the 0603 (mm) / 0201 (inch) size.### Operational Details* **Measurement Flow:** Involves setting measurement conditions on the instrument, performing fixture calibration (open, short, and electrical length compensation), connecting the DUT, and taking measurements. * **Calibration:** Open and short compensation are recommended, performed using furnished shorting devices or by leaving the DUT slot empty. Electrical length compensation is also a critical step. * **Electrode Maintenance:** Electrode deterioration can be checked by measuring the impedance in a shorted state using a suited shorting bar. This check is recommended daily and before fixture compensation.### Why Choose Aumictech for Keysight 16197A?At Aumictech, we specialize in supplying high-end impedance measurement equipment.
