Analog to Digital (A/D) Conversion Accuracy - The
3.5.8.4.1.2
A/D conversion shall be made to 12 bits of resolution. the conversion
accuracy over the temperature range -55C to +55C shall be:
(1) Within 12 arc minutes statically and dynam-
ically up to, but not greater than, an angle
rate of change of 15 degrees per second for all
synchro and resolver inputs, except conversion
accuracy for asterisk (*) inputs can be 18
arc minutes.
(2) Within 10% of full scale value for roll
gimbal temperature.
Analog Outputs - The SDC shall provide the following
