Avionics Bus Series

In the field of Avionics, efficient and precise testing solutions have always been the core driving force of technological innovation. CEMAI Measurement has launched new aerospace bus testing products — the MIL-1394B bus communication card, the MIL-STD-1553B Bus Communication Module, and the ARINC429 bus expansion module. These new products will bring entirely new value to the avionics testing field.

▍Product Overview:

1. MIL-1394B Bus Communication Card

The MIL-1394B communication card is a 3U PXIE board that complies with the MIL1394B (AS5463) protocol specification. The communication card supports 2 nodes, each providing three independent ports, and each node supports CC and RN modes. It is suitable for simulation and testing work for the MIL-1394B (AS5643) bus protocol.

▍Product Features

◆ Number of nodes: ≥2

◆ Supports cyclic and event messages

◆ Can simulate and inject faults such as package CRC errors, ultra-short frames, and ultra-long frames

◆ Equipped with send and receive buffers, hardware buffer: ≥256M

◆ Supports timestamp function with resolution better than 1 μs

◆ Supports dual modes CC (Cyclic Controller) and RN (Redundant Node)

◆ Supports real-time modification of STOF packets and messages

◆ Programmable STOF offsets, supports small message offsets

 

2. MIL-STD-1553B Bus Communication Module

The MIL-STD-1553B Bus Communication Module is a 3U PXIe-compliant standard board based on the MIL-STD-1553B protocol specification, and it conforms to the GJB289A-97 bus standard.
