In order to obtain the key parameters which required by the Vehicle-Carrying test, the multi-channel data acquisition system based on CompactRIO embedded platform was developed. This system was satisfied the requirement of high reliability, inexpensive, portable and rapid configuration, Then, synchronized control technology such as queue, FIFO, interrupt and the superior system architecture which is compare to the state machine has been introduced in detail. Finally, availability and stability of the system were proved through the pressure text of data acquisition.

Constant Field

The results of works aimed at increasing the level of uniformity of measurements of the magnetic induction of a constant field – the basic value in the field of magnetic measurements. A set of equipment for reproducing a unit of magnetic induction of a constant field in the range of 1–25 mT was created and described. The inclusion of this complex in the State primary standard of units of magnetic induction, magnetic flux, magnetic moment and magnetic induction gradient GET 12-2011 will ensure the reproduction and direct transmission of the unit of permanent magnetic induction in the ranges of not only weak (10–3–1 mT), but medium (1–25 mT) and strong (0.025–1 T) magnetic fields. A quantum cesium magnetometer based on the resolved structure of cesium atoms was created to transmit the unit of magnetic induction to the region of medium fields. The procedure for calculating the frequency conversion coefficients to magnetic induction of the created quantum cesium magnetometer is described. The uncertainty budget for reproducing a unit of magnetic induction of a constant field using the created complex is estimated.
