Applications:
Measure antenna electrical parameters: SWR, impedance (resistance + reactance), capacitance, inductance
Measure feed point impedance
Measure ground loss
Adjust antenna tuners and determine loss
Measure inductors and capacitors
Measure coax transmission line (SWR, length, speed factor, approximate and loss, resonant frequency, and impedance)
Measure and determine optimum settings for tuning stubs: SWR, approximate, resonant frequency, bandwidth, impedance
Determine characteristic impedance of transmission line
Determine length and wave phasing lines
Coaxial Cable Loss
Determine antenna tuner loss
Measure balun loss
Measure inductor
Estimate quartz crystal parameters
Measure magnetic loop resonance and SWR
