Vector Impedance Analyzer: VIA Echo
View DatasheetProduct Accessories

The Echo is a hand-held Vector Impedance Analyzer (Vector Network Analyzer), Spectrum Analyzer, Power Meter, and Frequency Domain Reflectometer (FDR) in one instrument. Echo models come in frequency ranges of 4MHz-to-1.0GHz or 4MHz-to-2.5GHz. The VIA Echo Network Analyzer was designed for performing antenna testing and tuning, transmission line testing and fault locating, cellular site turn-up testing and troubleshooting. It can be used for individual component testing, system or network testing. In a production environment Echo can be used to verify components and assemblies the same as equivalent Agilent (old HP) Network Analyzers at a fraction of the cost.

The VIA Echo’s all come with two ports S11 and S21 to perform both reflective and loss/gain measurements. The full suit of test parameters in the Echo instruments is:

  • SWR
  • Return Loss (dB)
  • Phase Angle
  • Reactance (X)
  • Resistance (R)
  • Impedance (Z)
  • Gamma Magnitude
  • Gamma Angle
  • Linear Gain
  • Phase Gain
  • Spectrum Analysis (specific models)
  • Frequency Domain Reflectometer (specific models)
  • Power Meter (specific models)

In addition to being a 1.0GHz or 2.5GHz Network Analyzer, the Echo is light at 2.2lbs (1Kg), compact, rugged, and weather resistant. It is portable and operates about 3 hours on a single charge. It has a backlit quarter VGA display that can show any two measurements bother graphically and digitally and a third measurement digitally only. Echo is self-calibrating and has a “Cable Null” feature, user friendly menus, and comes complete with a calibration load set.

Supporting Software - Echo PC Vision is supplied with every Echo to upload, customize, save, and print test results. Echo can be operated in remote control via the USB 2.0 connection with Echo PC Vision or upload any of 250 tests stored in its memory. Echo PC Vision adds full color graphics, Smith Chart and Spectrum Analyzer views with color markers
