• 1553 oriented menu prompts quickly set up test scenarios for testing and exercising 1553 RTs or BCs
• Compact 63B series enclosure
The Model C2253 Bus Analyzer is a powerful bench top unit designed to test Remote Terminals (RTs), Bus Controllers (BCs), and other terminal devices defined by MIL-STD-1553. An IBM or compatible PC serves as the primary user interface and test equipment controller. Using 1553 oriented menu driven prompts, the C2253 allows the user to quickly set up test scenarios for testing and exercising 1553 RTs or BCs. User test scenarios can be saved for future use or for later inclusion in complete production test programs.
The instrument level commands issued by the C2253 software to control each C2253 test scenario are saved in separate ASCII text files for later integration into more complex automatic testing procedures using any programming language of the user’s choice. Data responses from the UUT are stored internally in the C2253 and easily transferred to the PC (using menu selections) for display, further analysis, or archiving.
Gaussian noise test capability can be added to the Model C2253 as Option 01 to perform the complete noise rejection test specified in MIL-STD-1553.
The C2253 Bus Analyzer is contained in a single, portable, suitcase type package that is only 5 1/4 inches tall and weighs just 33 pounds. The unit may also be optionally rack mounted. Interfacing to the PC is by means of an IEEE-488 bus.
