    "abstract": "In this paper we present several techniques for characterizing longitudinal\nimpedances based on transient measurements of the growth rates and tune shifts\nof unstable coupled-bunch modes. These techniques are applicable to measurement\nof both fundamental and higher-order mode impedances and allow characterization\nof shunt impedances and quality factors of the HOMs. Methods presented here are\ncomplementary to lab bench measurements of RF cavities, in that the beam based\nmeasurements directly sense the physical impedance in the installed\nconfiguration. In contrast to a single-bunch integrated impedance measurement\nthese techniques resolve the impedances in the frequency domain. These methods\nallow determination of the impedance\u0027s unaliased frequency by analyzing\nsynchronous phase transients. Experimental results from ALS and BESSY-II are\npresented showing the use of these techniques to measure complex impedances.",
