Applications:
Measure antenna electrical parameters: SWR, impedance (resistance +
reactance), capacitance, inductance
Measure feedpoint impedance
Measure ground loss
Adjust antenna tuners and determine loss
Measure inductors and capacitors
Measure coax transmission line (SWR, length, velocity factor, approximate Q
and loss, resonant frequency, and impedance)
Measure and determine optimum settings for tuning stubs: SWR, approximate
Q, resonant frequency, bandwidth, impedance
Determine characteristic impedance of transmission line
Determine length of ? and ? wave phasing lines
Coaxial Cable Loss
Determine antenna tuner loss
Measure balun loss
Measure inductor Q
Estimate quartz crystal parameters
Measure magnetic loop resonance and SWR
Operation button definitions:
Mode: selects operation mode: impedance(default), complex impedance, capacitance, and inducatance
BAND: select band from any of the available bands: 160M to 6M
CONFIG: Provides menu for configurations and extended functions: PC Link, step size setting, suspend timeout setting, calibration, and software upgrade
SCAN: pressing this control initiates a scan of frequencies of the selected BAND. Scan exits to impedance mode showing the 2:1 bandwidth and the resonant point o the antenna
CAN(up): increase frequency and used to cancel operation for CONFIG menu
VAL(down): decrease frequency and used to validate operation for CONFIG menu
