This is an antenna analyzer for ham radio hobbyists. It can measure 50 ohms source impedance. It is also a meter for magnetic loop resonance, standing wave ratio, impedance... Features: Frequency generation & control: 1-60MHz.External power supply: 2.1mm power jack(center pin positive). 6 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). Operation: Manual control option displays SWR and complex impedance at selected frequencies Automatic scanning results displayed as frequencies of lowest SWR and complex impedance Battery operated for field use or use external 13.8V wall adapter Power saving modes Multi-point calibration for better accuracy Instrument Capabilities: 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; Determine length of ¼ and ½ 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; Specifications: Version Type: Ordinary Version / BT Version.
