Measuring Bit-Error-Rates of Forward Error Correction Code Encoded Signals

A device may include one or more components and a processor. The one or more components may obtain bit-error-rates of a signal and signal-to-noise ratios of the signal. The processor may select a target signal-to-noise ratio for the signal, determine a target noise level based on the target signal-to-noise ratio, set a noise level of the signal to the target noise level, determine a signal-to-noise ratio of the signal via the one or more components, adjust the noise level of the signal based on the determined signal-to-noise ratio, to stabilize the signal-to-noise ratio, determine a bit-error-rate of the signal via the one or more components, and record the bit-error-rate.
