VIA Echo™ Analyzer US Patent 7,030,627 B1 The Echo is a handheld Vector Impedance Analyzer, Spectrum Analyzer, Frequency Domain Reflectometer (FDR) and Power Meter for measuring antennas, networks, and cables. Echo has the capability of providing digital measurements and graphical sweep displays of impedance, RF power gain, or cable quality. The Echo’s testing functionality combined with it’s 4MHz to 1.0GHz or 2.5GHz frequency ranges makes it a versatile tool for numerous service applications. The Echo PC Vision™ software application, included with the VIA Echo, provides the user with the capability of remotely operating the VIA Echo through a USB port and view near realtime results or Echo’s stored tests on a PC. PC Vision provides color Cartesian and Smith Charts of vector plot data. The PC Vision software makes the capture, storage, and printing of documentation and reports easy. 4 Instruments in one hand-held package Vector Impedance Analyzer 3 Measurement Displays 2 graphical and 1 digital Spectrum Analyzer Broad or Narrow Spectrum Selection All information is subject to change without notice PC Vision Smith Chart
