	For the FAIR proton linac at GSI a 325 MHz 4-rod RFQ prototype has been built. On this prototype RF measure- ments have been carried out. After low power conditioning in cw mode the structure was high power tested in pulsed mode. During the performance tests the 6 stem prototype was optimized and has shown the feasibility of a dipole free 4-rod RFQ at high frequencies and was testet up to 120 kW per meter. In this tests the input power and the electrode voltage was observed using gamma spectroskopy. From this the shunt impedance was calculated and compared to other methods of measurements. The power test results are presented in this paper.

	The performance of an RFQ in case of its beam quality and transmission is in the basis dependent on the conformity of the field distribution of the manufactured structure with the one of its particle dynamic design. In the last years studies have been performed on the influence of various elements of the 4-rod RFQ on its field distribution. In particular the tuning process of the 4-rod RFQ with its tuning plates has been optimized. These studies have been complemented with detailed simulations on the fringe fields at the end of the electrodes and the conformity of the fields along the structure as well as the influence of other tuning elements like the piston tuner.
