Abstract
The Tune measurement system for HIRFL-CSR has been running in the commissioning of CSRm. The FFT method is used in the system. It is composed of two parts, one is a kicker system that is made up of a noise generator, an excitation kicker, a power amplifier and a switch for the excitation signal, another one is for measurement of the Tune that is made up of a beam position monitor, a 180° hybrid, a switch for the time delay of the synchronization and a real time spectrum analyzer. The principle and the results of the Tune measurement are introduced in the paper.
