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) Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. Products only include analyzers; Customers should provide DC5.5*2.1mm power cable and coaxial cable. Package List 1 x Analyzer(Power supply is not included)
