A device for detecting RF power information, for use as a stand alone purpose built device, or connectable to an external computing instrument such as a laptop, PDA, or cell phone, or other similarly capable technology. The device scans two or more bands in the wireless frequency and provides output to the user with wireless information about multiple bands of information. |

1. An system for receiving radio frequency signals and detecting radio frequency signals on at least two different bands, comprising:
an apparatus for detecting RF power on two or more radio frequency bands and that is connected to a computing device, the apparatus including:
a housing for enclosing components of the apparatus,an antenna attached to said housing for receiving radio frequency signals,a switch for selecting a band of radio frequency signals for detection by sending signals directly from the antenna to a radio system for detection when in a first position, and to a band pass filter when in a second position,a band pass filter for selecting a radio frequency band,a mixer for down converting radio frequency signals to a band received by said radio system,an oscillator for generating a local oscillator signal for said mixer, for defining the frequency of signals passed by said mixer, andsaid radio system comprising at least a first radio receiver configured to detect RF power in a single radio frequency band,wherein the apparatus determines the RF power of a first radio frequency band with the first radio receiver by routing via the switch first radio frequency band signals from said antenna to said radio system, andwherein the apparatus determines the RF power of a second radio frequency band with the first radio receiver by routing via the switch second radio frequency band signals from said antenna through said band pass filter for down conversion then through said mixer in which second radio frequency band signals are converted to said first band whereby said radio system can detect second radio frequency band signals; and a computing device with a graphical user interface and configured to display data received from the apparatus, wherein the data is a graphical representation of the RF power of the first radio frequency band and the second radio frequency band. |
