Moved circuitry of inertial referencing for Fast GVT to a wood plank to get it off of the power unit.
Converted .ati files for Scott P. for World View
Reviewed circuit diagram for inertial referencing circuit and compared against the actual circuit to make sure it was wired up correctly. The only differences I could see between the actual circuit and the diagram were 1) for the accelerometer signal conditioning, pins 1 and 8 are supposed to be connected for three of the stages by a variable resistor, and are not, and 2) there is no SW2 as is shown in upper right of diagram.
Performed noise floor on new Measurement Specialties accels (4002M1-002-060 and 4002M1-005-060). Tried using another, lower noise floor accelerometer to glue back to back with the test accel. Found out that some of the ICP sensors are very temperature sensitive. Just temperature deviations in the lab will cause the signal to wander a little. Also, just holding the accel for a little bit will cause serious drift to the signal. Lesson learned!
I am still unclear about what to do about the two resulting random signals. If you add two random signals, what is the resulting signal? Is it’s RMS value twice that of the other two? If not, why?
I also helped scott plot some old WV tests, and convert some .afu files from a local modes test I did awhile ago.
