1 This is not an EMC analyzer specication; 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 .
