Champ Signal Strength Meter

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.

Champ FAQs

Can I export Champ data into my favorite mapping program?
Yes. Champ supports a variety of post-processing software.


How do I get the data into my PC?
Use the Champ Data Logger and then upload that data through the serial port of your PC in either binary or ASCII delimited format or through the PCMCIA storage card included with your Champ.
