• 3U cPCI instrument (compatible with 3U PXI)

describe

The QCP-1553 module is a robust, reliable, and fully functional Compact PCI module designed to provide independent MIL-STD-1553A/B interfaces for aviation electronics applications. The 3U QCP-1553 module supports up to four independent dual redundant MIL-STD-1553 data bus streams. In addition, the module also provides full functionality testing, simulation, monitoring, and data analyzer functions for MILSTD-1553A/B applications. The onboard IRIG-B time code decoder and generator allow users to accurately synchronize single or multiple QCP-1553 modules to a common time source. The QCP-1553 module can be configured with single or full functionality (RT simulation, monitoring, and bus controller).

The standard features of QCP-1553 include selectable transformers or direct couplings, 1 MB of RAM per channel, 45 bit message timestamps, triggers, a wide range of BC&RT link list structures, error injection/detection, avionics grade discrete, automatic/manual RT status bits and mode code responses, and advanced BC functionality. An IRIG-B signal receiver/generator supports DC/TTL signals from the generator, and the receiver supports AM or DC/TTL signals. The QCP-1553 bus monitor features the industry's fastest encoder/decoder, providing unparalleled error detection capabilities and 100% full load bus monitoring.

The QCP-1553 multifunctional interface can be easily configured to simultaneously serve as a bus controller, 31 remote terminals, and bus monitor.

The single function QCP-1553 interface has all the functions and functionalities of the multifunctional version, but can only enable one main operating mode at a time. Each interface can simulate a bus controller or 31 remote terminals or bus monitors.

Bus controller function

• Programmable control:
  • Main and secondary frame content and timing
  • Message interval time
  • Response timeout and delayed response
  • Multiple BC retries
• Modify messages, data, or settings while the card is running
• Insert irregular messages into the running BC list
• The 'Oneshot' mode is used to simplify BC operations
• Conditional message sorting based on real-time message data or status
• Interrupt generation and status messages can be selected based on system conditions or all detected errors across the entire system
• Full error detection:
  • INVALID WORD
  • Late response
  • Bit count error
  • Early response
  • High character
  • not responding
  • low word
  • The RT address is incorrect
  • anti-phase synchronization
  • parity error
  • Manchester error
• Widespread programmable error injection (based on each word)
• Synchronize BC operations to an external time source

Remote terminal function

• Multiple RT simulations (up to 31 RTs)
• Programmable error injection (based on each word)
• Modify data, status words, or settings while the card is running
• Programmable message content (link message buffer)
• Interrupts can be generated based on each message
• Message termination and error conditions
• RT map monitoring

Bus monitoring function

• Capture 100% full load bus traffic:
• Time Tag - Error Status
• Word Status - Message Status
• RT response time
• Interruption can be selected by RT/SA/WC
• Wide range of filtering and triggering options:
• Through independent RT/sub address
• Send, receive, or broadcast mode codes
• Internal or external triggering
• Trigger the output of user specified data
• Real time bus playback using RT editing mode
