Vector Impedance Analysis

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 are:

*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.
