SARK100 1-60MHz HF ANT SWR Antenna Analyzer Meter Standing

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 inducatanceBAND: select band from any of the available bands: 160M to 6MCONFIG: provide menu for configurations and extended functions: PC Link step size setting suspend timeout setting calibration and software upgradeSCAN: 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 antennaCAN(up): increase frequency and used to cancel operation for CONFIG menuVAL(down): decrease frequency and used to validate operation for CONFIG menuSpecifications:Frequency Generation Control: 1-60MHzSource Impedance: 50 ohmsStability: (+/-) 100 ppmSpectral Purity: Harmonics Down - TBD dB beyond 60MHzStep Size: User configurable increments of 100Hz 1KHz 10KHz and 100KHzUsable Measurement Range: SWR: 1.0 to 9.99Impedance: Approx. 5 to 2000 ohmsRF Output: Adjustable: 2.0 Volts pp (typ)RF Out: BNCConnectors: RFPower Supply(NOT Included): Powered by External: DC 12-14V 500mAExternal Power: 2.1mm Power Jack (center pin positive)USB Interface: Mini USB ReceptacleItem Size: 14.8 * 8.7 * 3.3cm / 5.83 * 3.43 * 1.3in (L * W * H)Item Weight: 536g / 18.91ozPackage List:1 * ANT SWR Antenna AnalyzerEnglish User Manual:https://www.dropbox.com/s/z2t3t73lwpsq3ha/SARK100%20User%20Manual.pdf?dl=0Software Installation:https://www.dropbox.com/s/wl7vvd2gobm4xaf/WinPCC-Sark100%20EN%20V0.8.exe?dl=0
