Wireless equipment diagnosis system

A wireless data acquisition equipment comprising:

• interrogator means;
• and
• one or more transponder means for receiving interrogatory signals from said interrogatory means and then transmitting to the interrogatory means the interrogatory signals after modulating the interrogatory signals using a modulator means with data measured by the one or more transponder means, said one or more transponder means comprising:
• an antenna means for receiving said interrogatory signals and for transmitting the modulated interrogatory signals to said interrogatory means;
• said modulator means for modulating said interrogatory signals;
• detector means for detecting said interrogatory signals and for outputting a detected signal represending said interrogatory signals;
• a control circuit means for receiving said output signals from said detector means and for generating control signals;
• and
• an interface section for transferring said detected control signals to a host computer, said interface section comprising
• line driver means for receiving data from said host computer;
• an interface circuit means for outputting said received signal from said host computer;
• and
• wherein said modulator means modulates said interrogatory signals based on output from said control circuit means.
