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.
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.
