  To understand and control the dynamics in the longitudinal phase space,
time-resolved measurements of different bunch parameters are required. For a
reconstruction of this phase space, the detector systems have to be
synchronized. This reconstruction can be used e.g. for studies of the
micro-bunching instability. It occurs if the interaction of the bunch with its
own radiation leads to the formation of sub-structures on the longitudinal
bunch profile. These sub-structures can grow rapidly -- leading to a
sawtooth-like behaviour of the bunch. At KARA, we use a fast-gated intensified
camera for energy spread studies, Schottky diodes for coherent synchrotron
radiation studies as well as electro-optical spectral decoding for longitudinal
bunch profile measurements. For a synchronization, a hardware synchronization
scheme is used which compensates for eventual hardware delays. In this paper,
the different experimental setups and their synchronization are discussed and
first results of synchronous measurements are presented.
