We present the performance and limitations of the SPS exponential coupler for transverse instability measurements with LHC type beam. Data were acquired in 2008 in the SPS in the time domain with a bandwidth of up to 2.5 GHz. The data were filtered to extract the time evolution of transverse oscillations within the less than 5ns long LHC type bunches. We describe the data filtering techniques and reveal the limitations of the pick-up due propagating modes.
