GSA Schedule Contract


The BCIT test equipment contains rugged deployable, commercial test instrumentation, packaged in a single mobile, portable container with a laptop computer built in, for easy flightline avionics maintenance.

BCIT test functionality applies to a variety of systems, including aircraft, tanks, spacecraft, and ships, which rely upon MIL-STD 1553 data bus architectures to link their supporting electronic systems (e.g., avionics) into an integrated data distribution network.




Transportable Container

The ruggedized, transportable container holds the PXI Chassis and all of its components. The container is held in a case with rollers and a handle, making it easy to move from site to site. The case has a weather-tight seal that helps it withstand adverse weather conditions, such as wind and rain, when the doors are secured.

The unit itself is also ruggedized and portable. It is lightweight, with handles for easy carrying. When closed, the unit can withstand a drop of 12” or a fall from tipping over with no adverse effects.

System Components

The BCIT System consists of :

  • PXI Chassis with Controller
  • MIL-STD-1553 Probe
  • BCP Probe
  • Removable PXI Hard Disk Card


The STX-EC Controller consists of a mezzanine card, XTX processor board, controller board, and front panel. This unit as a whole is referred to as the STX-EC Controller.

The Controller is the central processing unit for the system. It is capable of interfacing with multiple probes through a PXI backplane.

The controller communicates via Ethernet to the software, logs data from the probe(s) to the hard disk drive, oversees inter-probe communication, and maintains time synchronization.

The Controller is designed to run Windows XP Embedded and SystemTrace® software, and provides an easy to use, programmable interface.


MIL-STD-1553 Probe

Bus Monitor Status Screen - Bus Controller, bus emulator, bus monitor

Bus Monitor Status Screen

The 1553 probe provides the capability to monitor up to four dual-redundant MIL-STD-1553 buses simultaneously. The probe collects and filters MIL-STD-1553 data traffic, contains trace and history memories for buffering collected data, and provides the capability to collect bus statistics.

The Bus Monitor software application processes and displays statistics data from the 1553 probe.



Time Domain Reflectometer

TDR Status Screen - Bus Controller, bus emulator, bus monitor

TDR Status Screen

The BCP 1553 probe provides Time Domain Reflectometry (TDR). It samples the waveform of a transmitted pulse, which provides information about the characteristics of the cable under test.

The probe is a PXI device consisting of a transmitter card and receiver card. The transmitter produces a sharp-edged pulse on the cable under test, while the receiver samples the voltage changes on the cable.

The TDR mode provides features for fault-finding on MIL-STD-1553 cable systems. This allows the user to analyze the attached cable to identify shorts and breaks in the cable. The BCIT has the ability to locate faults within six inches given an accurate VoP of the cable.
