Abstract	A beam-based test bench is proposed for the ILC Crab Cavity system. The RF phase and amplitude imbalance in the pair of the electron and positron cavities, a harmful spurious odd field component, and some effects of beaminduced field can be measured and investigated. The test bench comprises two fully powered crab cavities, a RF reference distribution circuit, two upstream reference BPMs and two downstream BPMs measuring the imbalance differential kick produced to a traversing low energy bunch. The set-up is insensitive to bunch arrival time jitter and RF phase Common Mode jitter. With two pairs of BPMs, it is insensitive to bunch trajectory jitter as well. Similar BPM set-up with single dipole cavity can be used as a high resolution bunch arrival time jitter monitor.
