    This paper presents a flexible testing method and the steady-state compliance of PMUs under the C37.118.1a amendment. The work is focused on the changes made to the standard for the harmonic rejection and out-of-band interference tests for which the ROCOF Error limits have been suspended. The paper aims to provide an indication whether these limits should be reinstated or not. The test platform consists of a test signal generator capable of providing three phase voltages and currents, and playing back digitized files, PMUs under test, and a PMU test result analysis kit. Three PMUs from different vendors were tested simultaneously in order to provide a fair comparison of the devices. The results for the steady state tests are discussed in the paper together with the strengths and weaknesses of the PMUs and of the test setup.
