(57) Abstract:
A system provides evaluation of stability of an on frequency repeater.
A unique signature is imposed on RF signals transmitted by the
repeater, and RF signals received by the repeater are analyzed to
detect signal components corresponding to the signature. The
signature signal is composed of a sequential series of signal pulses
separated by a quiescent period. Respective transmit and quiescent
power levels of signal components of the input signal received by the
repeater are detected. These power levels are then used to estimate the
system stability.
