Berkeley Valtronics The Fox
This compact 5 pound hand-held, battery-powered meter is packed with exceptional capabilities. The Fox is designed to measure RF propagation coverage and detect "RF Shadows". It is internally powered (or maybe externally) and logs text measurements, or displays graphically a wide assortment of built-in real-time macro measurements. These include "follow mode", C/I, RSSI, adjacent channel, "best server", peak hold, A-band or B-band scan and BER analysis.

POST-PROCESSING
Data from The Fox Meter measurements are saved to a 2 Mbyte PCMCIA flash card and to an RS-232 serial port for direct storage to a PC (up to 38K baud, selectable). Serial output may be binary (compressed) or in an ASCII comma delimited format.
