###### Appendix 3 to ETSO-C69c – Measurement of loads on the attachment(s) to the airplane *ED Decision 2003/10/RM* Data acquisition systems which utilize an analog-to-digital (A/D) converter to process the electronic signals from load cells must be configured to accurately record loads during a test. The following parameters are recommended for recording with an A/D converter system: 1. Sample Rate 20 Hz minimum 2. Resolution 12 bits minimum 3. Anti-aliasing pre-filter 5 Hz low pass (0 to -4 dB at 5 HZ), -20 dB/decade rolloff at frequencies above 10 Hz The signal amplifier should provide sufficient gain so that the expected full-scale, or highest anticipated value to be recorded, is at least 70 percent of the maximum input range of the analog-to-digital converter (A/D). No post acquisition digital filter, smoothing, or averaging algorithm may be applied to the data.
