21.4 MHz crystal and LC bandwidth filters on the
A11 and A13 Bandwidth Filter assemblies. The
self-calibration routine produces DAC values

that adjust each bandwidth to within ±20%.
The 9 kHz and 120 kHz entries are for the 6 dB EMI
resolution bandwidths. All other entries are for the
3 dB resolution bandwidths.
