VIA Echo 1000, 1000SF & 2500 Combined Operator Training

  1. 1. VIA Echo 1000, 1000SF & 2500 Combined Operator Training
  2. 2. Table of Contents Slides 1 Introduction & Echo Package 2- 5 Why Vector Impedance Analysis 6-12 VIA Echo Operation Power and ON/OFF 13-16 Function Keys 17-35 LCD Screens 36-41 Echo PC Vision 42-51 Bonus Uses for VIA Echo 53-54 Cleaning and Maintenance 55-56 Questions and Answers 57
  3. 3. VIA Echo is: The smallest, lightest 1.0GHz or 2.5GHz Vector Impedance Analyzer on the market Designed for wide Frequency Ranges: Echo 1000 = 4MHz to 1.0GHz Echo 1000SF = 4MHz to 1.0GHz Echo 2500 = 4MHz to 2.5GHz 1000SF & 2500 models have a Spectrum Analyzer and Frequency Domain Reflectometer Full featured and Dual-Port [S11 & S21] on all models 2
  4. 4. What’s in the Package VIA Echo Belt Case with shoulder strap Operator Manual Quick Start Guide USB Cable N-Terminator’s, Short & 50 Ohm AC Wall Charger Soft Carrying Case Options N-to-SMA Adapter Kit N-Female Terminator Set DC Vehicle Charger 3
  5. 5. S11 Port Total Z Reactance Z Angle Return Loss Resistance Gamma SWR Gamma Angle FDR Input S21 Port Gain (loss) dB Lin or log Gain Angle Group Delay Spectrum Analyzer Cooling intake 4
  6. 6. Quick Start Guide Short & 50 Ohm Terminators Echo CD Echo PC Vision Operating Manual Quick Start Guide VIA Application Notes Echo Training PPT 5
  7. 7. Why Use a Vector Impedance Analyzer?  Scalars provide SWR & Return Loss information, but not Vector Impedance. A high SWR reading doesn’t tell you what to fix or what to tune in an antenna system  The VIA Echo’s information can be used to: Maximize an antenna system’s efficiency Document an installation with electronic or paper media Diagnose an Antenna System to effect timely repairs  The VIA Echo can be used at the antenna base or at the feed line using the “Nulling Cable” feature 6
  8. 8. VIA Echo vs Scalar SWR SWR Return Loss Return Loss Impedance (Z) Z Angle Reactance Resistance Gamma Magnitude Gamma Angle Linear/Log Gain Phase Delay Group Delay (Spectrum Analyzer & FDR option) 7
  9. 9. What Chokes an Antenna? Resistance Inductance Capacitance Impedance Reactance Frequency Resonance Impedance Angle Reflection Coefficient All the factors for antenna performance MUST balance or the result is Power Loss from out-of-phase current and voltage and increased VSWR from impedance mismatches 8
  10. 10. Vector Impedance and the Right Hand Plane (RHP) X = Reactance, Z = Total Impedance, R = Resistance, θ = Z Angle, and i or j = square root of -1 Above, the positive X values plot into one quadrant of a Cartesian graph’s RHP, negative X values plot in the other quadrant directly below this one 9
  11. 11. Mapping the RHP to a unit circle – Smith Chart Note where Zo plots – Dead Center is Antenna System Perfection Inductive ResistiveLow Z High Z Capacitive 10
  12. 12. Smith Chart from Antenna Sweep As the frequency changes the antenna’s reactance moves from inductive to capacitive with some impedance change and is resonant slightly off the center of the swept frequency 11
  13. 13. ELI the ICE Man For best performance an antenna should be purely resistive and resonant near Zo at the center frequency (Fc) Power loss factors include: If the antenna is inductive, voltage will lead current (ELI) If the antenna is capacitive, current will lead voltage (ICE) Either of these conditions exceeding the manufacturer’s specifications require corrective action by tuning the antenna or adding a tuning stub 12
  14. 14. VIA Echo’s Operation 13
  15. 15. AC or DC Power and Recharging 100-240 VAC 50/60 Hz AC power permits operation AND Recharging (OPTIONAL) 14 12.5 VDC @ 500 mA Vehicle running is preferred DC power permits operation OR recharging, but not both
  16. 16. Battery Installation CAUTION NO mixing cells Same Type & mAhr 15 BATTERY MENU Select Alkaline or NiMH/NiCd and enter rated mAhrs Date/Time can only be retained for 60 seconds without batteries
  17. 17. Soft Reset Press ON and then Quickly pressing ENTER 4 – 5 times performs a soft reset & restores factory default settings 16 Powering ON Pressing ON/OFF starts the unit, performs a self-check, calibration and restores the last used settings Hard Power Down Press and HOLD the ON/OFF key for 10-15 seconds to force a power down.

  56. 56. Cleaning Your VIA Echo 1. Always spray cleaners and rinse water on a soft cloth, do NOT spray directly on the instrument Soft Cases The soft case should be cleaned the same as the instrument. Use a soft bush to remove tough dirt. Do NOT immerse in water or dry in a dryer. Wash and Dry separately, both instrument and case should be dry before enclosing the instrument in the case. 2. Typical Grime – Use a mild non-abrasive detergent like 409® in water or glass cleaner (non-ammonia) and rinse water to clean 3. Cable Gel – User liquid “citrus” cleaner to remove 4. Tar, creosote or adhesives – Use WD40® followed with mild detergent and water 55
