RF Attenuators

  1. DIY attenuator

Inductors

  1. Measure inductance and capacitiance values with VNA: 3 methods depending on impedance
  2. Measure inductor saturation current
  3. Transformer saturation current can also be measured by applying DC-current to the primary winding, in series with an HF-decoupling inductor (many times the value of the inductor you want to measure and it should also have many times the saturation current).  Then you can connect an L-meter to the secondary winding and start measuring.

Capacitors

  1. Measure capacitance value with DC-offset : Ceramic Capacitor with DC bias value measurement. LCR Meter
