Abstract

See full text

A measurement apparatus and method for triggering and making analog measurements of radio frequency (RF) bursts in a time domain multiple access communications system. An RF level detector or edge detector triggers an analog sampler which acquires measurement data from a spectrum analyzer or an RF peak detector. A digital signal processor processes the RF burst to detect a known bit sequence and calculates a timing relationship between the triggering of measurement samples and transmitted data bits in the RF burst. A host processor uses the calculated timing relationship to identify and analyze the measurement data pertaining to desired measurements of the RF burst.
