Abstract

A device for monitoring a signal, comprising: a combiner (103, 303) configured to combine the received signal to be monitored with an impairment signal; a signal spectrum analyzer (105, 305) configured to analyze spectrum of a signal output from the combiner (103, 303) upon receiving a trigger signal; a signal quality analyzer (108, 308) configured to analyze the signal output from the combiner and output a signal quality factor; a trigger generator (110, 310) configured to monitor the signal quality factor and output the trigger signal upon detecting the signal quality factor below a trigger threshold level; and an impairment simulator (112, 312) configured to generate the impairment signal and an impairment scaler (113, 313) configured to scale the impairment signal and input the scaled impairment signal to the combiner (103, 303).
