Mini HF ANT SWR Antenna Analyzer SARK100  
For Ham Radio Hobbists

        Precise and self-calibrating reflectometer design measures forward and reflected signals and impedance data
        Display 2x16 with optional backlight
        Precision DDS signal generator (AD9851) used as signal source
        USB port connects to PC for field-upgradeable software and uploading of real-time measurement data
        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 adaptor
        Power saving modes
        Multi-point calibration for better accuracy
    Instrument Capabilities:
        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 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
