This is the difference between the measured DC gain and the nominal DC gain, divided by the nominal
DC gain and expressed as a percent.

Analog Bandwidth De fi ned in Section 4.6 of IEEE std 1057. The difference between the upper and lower frequencies, at
which the amplitude response, as seen in the data record, is 0.707 (-3 dB) of the response seen in the
data record at the speci
fi ed reference frequency. Speci fi es only the -3 dB point. It does not include
the in-band response.
