摘要:
The present invention relates to an IQ imbalance measuring device and an IQ imbalance measuring method and, more specifically, to an IQ imbalance measuring device and an IQ imbalance measuring method for an optical receiver. The IQ imbalance measuring device according to the present invention comprises a light generating unit generating an optical signal and a reference signal and providing an optical receiver with the optical signal and the reference signal; a graph creating unit creating a Lissajous figure by using an I signal and a Q signal output from the optical receiver in response to the optical signal and the reference signal; and a calculating unit calculating IQ imbalance of the optical receiver with reference to the Lissajous figure. The IQ imbalance measuring device and the IQ imbalance measuring method according to the present invention can measure IQ imbalance for the optical receiver with few calculations on a low speed signal.
