Introducing the New

VIA Echo Vector Impedance Analyzer, Spectrum Analyzer

 and  FDR

The Echo is a handheld vector impedance and  spectrum analyzer with FDR  for 

measuring antennas, networks and cables. The 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 its 100 KHz to 1.0 GHz 

or 100 KHz to 2.5 GHz frequency ranges makes it a versatile tool for numerous 

service applications including :

The Echo PC Vision TM  software application, included with the VIA Echo, provides the 

user with the capability of remotely operating the VIA Echo through a USB port while 

viewing real time results or stored data 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. (Available in Aug. 2006)
