This is an antenna analyzer for ham radio hobbyists. It can measure 50 ohms source impedance with the error of (+/-)1 ohm. It is also a meter for standing wave, impedance, capacitance...
Features:
Frequency generation & control: 1-60MHz.
External power: 2.1mm power jack(center pin positive).
5 operation buttons, easy and convenient to operate.
Installed black metal case, just connect the power(not included) and then work.
Step size: user configurable increments of 100Hz, 1KHz, 10KHz, and 100KHz.
Support measuring data waveform analysis via connecting computer with USB cable(not included).
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, 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;
Measure magnetic loop resonance and SWR;
Operation Buttons Definitions:
MODE: select operation mode: impedance(default), complex impedance, capacitance, and inducatance
BAND: select band from any of the available bands: 160M to 6M
CONFIG: provide menu for configurations and extended functions: PC Link, step size setting, suspend timeout setting, calibration, and software upgrade
SCAN: press this control to 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
