This compact (less than 5 lbs.) hand-held, battery-powered meter is packed with exceptional capabilities. The Champ® is convenient for finding RF "shadows" in indoor wireless systems for drive-around studies to detect RF leakage and propagation coverage. The PCMCIA memory system stores data for post processing.

Champ Software

Data from the Champ measurements are saved to a 2 Mbyte PCMCIA battery backed-up card and to an RS-232 serial port for direct storage to a PC (up to 38K baud, selectable). The PCMCIA card data can be down-loaded to a PC using the supplied PC software. Serial output may be binary (compressed) for later conversion or in an ASCII comma delimited format. The Champ data can be imported directly into third-party software including spread sheets, such as EXCEL or propagation analysis software such as TEC's Wizard. Visit our Technical Support section for updated downloads of this software, demos and more...
