Avionics Interface Technologies has released new MIL-STD-1553 and ARINC429 test and simulation modules for the PXI form factor. The PXI-C1553 and PXI-C429 are 3U PXI Hybrid Slot compatible instruments designed to support testing, simulation, monitoring and analysis of MIL-STD-1553A/B databuses and ARINC429 data channels.

AIT’s test and simulation modules use an innovative FPGA[]-based hardware architecture, with an embedded processor, scalable memory, and an IRIG-B time code generator/processor. Every AIT module comes with high-level device driver support, object-oriented software library cells, Object-oriented Wrapper Layer (OWL) and Remote OWL Server (ROS).

The PXI-C1553 and PXI-C429 modules are supported by AIT’s industry-leading Software Development Kit (SDK) and Flight Simulyzer Graphical User Interface (GUI) analyzer software. Both modules also provide full error injection and detection as well as support for PXI triggering and synchronized time-tagging to the PXI 10 MHz clock.

The PXI-C1553 module is capable of simultaneously simulating a MIL-STD-1553 Bus Controller (BC), up to 31 Remote Terminals (RT), and a Chronological Bus Monitor (BM) on each channel. Single, dual, and quad channel options are available. The BC provides real time BC simulation functions supported by the PXI-C1553’s onboard advanced FPGA. Precise timing and sequencing of bus commands, within minor/major frames, is handled onboard supporting autonomous operations. The PXI-C1553 is capable of simultaneously simulating up to 31 RTs. Each RT provides fully programmable and intelligent responses to BC commands, including intelligent mode code responses and application selectable response times. Each RT may also be configured to operate in a monitor only mode in which it only stores data sent to it, while not responding to BC commands. The BM supports 100% time tagged data capture and archiving to disk. Full error detection capabilities are provided as well as support for advanced filtering and triggering.

The PXI-C429 module supports simulation of up to 32 ARINC429 transmitter/receiver channels concurrently. Each channel is fully programmable as input or output. Bit transmission rates and duty cycles are selectable for each channel and the 12.5 kbits/sec and 100 kbits/sec transmit modes are supported. Associated rise and fall times are in accordance with the ARINC429 electrical specification.
