What physical parameter does a slotted line measure?

Answer 1

A Slotted line carriage ; a microwave instrument used to measure like

1. Wavelength

2. VSWR and SW Pattern

3. reflection coefficient

4. Impedance

5. Return loss measurements

Answer 2

Slotted lines can measure standing wave amplitude, standing wave ratio,

wavelength, and a number of other parameters including impedance and

reflection coefficient.
