You info is not enough. For a cyclic transmitter there is a transmission duty cycle and repetition cycle. From what I understand, you are trying to measure repitition cycle. But, What is the duty cycle of your transmitter (the time it will stay ON)? For example, Blue tooth is a frequency hopping device. It hops 1600 hop/sec. This means the duty cycle for it is 625usec.
