A new coupler test bench based on a resonant ring has been built at ELBE in Dresden-Rossendorf to run warm window as well as coupler tests with RF power up to 190 kW (warm window tests up to 250kW) in CW operation. The ring is driven by a 10 kW klystron. This test bench also includes liquid nitrogen cooling of the ceramic cold window of the RF-coupler which allows testing under almost real conditions. A special waveguide to coupler transition was designed to match couplers with different antenna tips. At the beginning with the test bench it was possible to test the warm windows used at ELBE. It has been shown that the used warm windows are usable up to 70kW of CW-RF power with additional air cooling, much more than the 10kW CW used at ELBE. After this test the coupler used at the ELBE cryomodules was tested, in CW operation a power level of about 20kW was reached. More tests are in program and in near future some improvements are planned.
