1 This is not an EMC analyzer speci￿cation; however, the 300 Hz span is tested to 65 % to keep the narrow bandwidth accuracy and residual FM measurement uncertainty at a minimum. If the 300 Hz span accuracy is >5% the additional measurement uncertainty may need to be included for the bandwidth accuracy and residual FM measurement uncertainties .
