3. Switch to the Show all mode and read the value of capacitance or inductance.

Unknown capacitor Unknown inductor
5.3.2. Transformers
RigExpert analyzers can also be used for checking RF transformers. Connect a 50 Ohm
resistor to the secondary coil (for 1:1 transformers) and use SWR graph or R,X graph
modes to check the frequency response of the transformer. Similarly, use resistors with
other values for non-1:1 transformers.
5.3.3. Traps
A trap is usually a resonant L-C network used in multi-band antennas. By using a
simple one-turn wire coil a resonant frequency of a trap may be measured.
Example:
A coaxial trap constructed of 5 turns of TV cable (coil diameter is 60 mm) was
measured:
