MezaBOX - a mezzanine carrier in the LXI standard is a device that ensures the functioning of various modules installed in it, made in the form of mezzanines, under the control of a personal computer. MezaBOX is intended for use as mezzanine carriers in multichannel systems for collecting / issuing information of both digital and analog form.
The main function is to accumulate a large amount of information in the form of binary codes coming from mezzanines at high input frequencies and a large number of channels when it is not possible to process data in real time.

In the mode of issuing information on mezzanines, MezaBOX provides the output of data recorded in its internal memory at specified intervals in a single time grid to specified mezzanines.

The MezaBOX device in the LXI standard performs batch buffering of data from dissimilar mezzanines with data binding to a single time grid and provides access to the current (received at the last moment of time) measurement results on any channel. It also provides interaction with an external personal computer via USB or ETHERNET message-based interfaces. The device complies with the “C” class of LXI devices according to IEEE 1588 standard and USBTMC-USB488 (USB Test and Measurement Device) device class.
