Description: This is a SWR analyzer for ham hobbyists. With 5 buttons, "Mode", "Band", "Config", "Scan", "Up", "Down", you can selects operation mode, band and extended functions. It is powered by DC 12 to 14V 500mA external power with 2.1mm power jack, and can be used to m easure antenna electrical parameters, SWR, impedance (resistance + reactance), capacitance, inductance, feed-point impedance , ground loss , etc. Features: SWR usable measurement range of this analyzer is 1.0 to 9.99. step size: user configurable increments of 100Hz, 1KHz, 10KHz, and 100KHz. Powered by DC 12 to 14V 500mA e xternal power with 2.1mm power jack(center pin positive), just connect the power and then work . 5 operation buttons are easy and convenient to operate. You can s elects operation mode, band and extended functions. Beautiful and simple designed black case would protect the antenna analyzer from external damage. This would be a great SWR a ntenna analyzer for ham hobbyist or professionals. Specifications: Frequency Generation & Control: 1 - 60 Mhz Source Impedance: 50 Ohms Stability: +/- 100 ppm Spectral Purity: Harmonics down >- TBD dB beyond 60 MHz Step Size: User configurable increments of 100 Hz, 1 kHz, 10 kHz, and 100 kHz SWR Usable Measurement Range: 1.0 to 9.99 Impedance: Approx. 5 to 2000 ohms RF Output: Adjustable 2.0 Volts pp (typ) Power Supply: Powered by external 12 to 14V DC, 500mA Push Buttons (5): "Mode", "Band", "Config", "Scan", "Up", "Down" Switch: "Power On" Connectors: RF USB: Mini-B receptacle External Power: 2.1mm Power Jack (center pin positive) Size: 150 x 90 x 40mm / 5.9 x 3.54 x 1.57" Applications: 1. Measure antenna electrical parameters: SWR, impedance (resistance + reactance), capacitance, inductance 2. Measure feed-point impedance 3. Measure ground loss 4. Adjust antenna tuners and determine loss 5. Measure inductors and capacitors 6. Measure coax transmission line (SWR, length, velocity factor, approximate Q and loss, resonant frequency, and impedance) 7. Measure and determine optimum settings for tuning stubs: SWR, approximate Q, resonant frequency, bandwidth, impedance 8. Determine characteristic impedance of transmission line 9. Coaxial Cable Loss 10. Determine antenna tuner loss 11. Measure balun loss 12. Measure inductor Q 13. Estimate quartz crystal parameters 14. Measure magnetic loop resonance and SWR Operation Button Function: Mode: Selects operation mode, impedance(default), complex impedance, capacitance, and inductance 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 Package Includes: 1 x Analyzer(Power supply is not included)
