The STX 1553 Monitor/Analyzer, powered by ITCN’s Real-Time Trace™ technology, is designed for use in the SystemTrace STX platform for network-centric instrumentation. The 1553 Monitor is capable of recording activity on up to four dual redundant MIL-STD-1553 buses. This allows the analysis of data transfers between all devices that participate in data transfers on the network.

Data is monitored by symbolically specifying MIL-STD-1553 Terminals, Sub-Addresses, Messages, Mode Codes, and Data Words, then selecting the items from this list as “Events” (Filters) on the bus for the test unit to monitor and record. Conditions for Event recording may be setup by the user, such as, number of Event occurrences, elapsed time, or a dependence on the occurrence of other Events.

Up to 256 unique Events (Filters) may be monitored per channel for each data collection session. Symbols may be defined from single bit size to Double Precision Floating Point values. Activity on the Bus may be recorded at the RT, RT+SA, Message, Mode Code, or Data Word level, or any combination of these.

In addition to event capture and anlysis, a parallel circular history buffer with a 100K window may be enabled allowing the test unit to collect all activity from the time the target is powered up until the History buffer is triggered or the unit is stopped. Pre- or post-trigger events may be designated to record activity preceding and following the trigger.
