  In this paper, we analyze the error probability of reconfigurable intelligent
surfaces (RIS)-enabled communication systems with quantized channel phase
compensation over Rayleigh fading channels. The probability density and
characteristic functions of the received signal amplitude are derive dand used
to compute exact expressions for the bit error rate(BER). The resulting
expressions are general, as they hold for an arbitrary number of reflecting
elements N, and quantization levels, L. We introduce an exact asymptotic
analysis in the high signal-to-noise ratio (SNR) regime, from which we
demonstrate, in particular, that the diversity order is N/2 when L=2 and N when
L >2. The theoretical frameworks and findings are validated with the aid of
Monte Carlo simulation.
