This unit
The DDC BUS-68005 is a portable MIL-STD-1553 data bus exerciser that simulates, tests, and troubleshoots MIL-STD-1553A and 1553B communication systems. It delivers full-function simulation of both Bus Controller (BC) and Remote Terminal Unit (RTU) operations, supporting up to 8 simultaneous RTU simulations with flexible memory mapping for real-time transmission and reception. The exerciser implements protocol tests from the SAE AE-9A Production Test Plan, including RT Address, Word Count, Subaddress, Error Injection, Dual-Redundant Operation, Mode Commands, Status Word, Broadcast Messages, and RT to RT Transfers.
Technical Specifications
System Compatibility: MIL-STD-1553A and MIL-STD-1553B
Functional Simulation: BC simulation supports BC-to-RT, RT-to-BC, and RT-to-RT message formats; can simulate both BC and one RTU in RT-to-RT transfers
Remote Terminal Capacity: Up to 8 simultaneous RTU simulations with mapped memory blocks for real-time operation
Response Time: 6 to 31 microseconds in 1-microsecond increments
Message Gap: Variable
Transmitter Amplitude: Variable
Response Time-Out: Programmable
Error Modes: Single, Repeat, or Halt-on-Error operation; detects response time, continuity, fail-safe timeout, Manchester coding, sync, parity, and bit/word count errors
Data Storage: Internal RAM for message/command data, block linking information, transmit/receive words, and control word parameters
Key Features
Local programming via 24-pad keyboard and 10-character alphanumeric display
Remote programming via 8-bit parallel I/O, RS-232, or IEEE-488 (with DMA support)
Full RS-232 CRT terminal control for low-speed commands
High-speed command interface using single-character ASCII mnemonics with binary byte parameters
Error generation and detection with comprehensive diagnostic flagging
Built-in power-on self-test
Typical Applications
MIL-STD-1553 system validation and production testing
Remote terminal protocol compliance verification
Bus controller functional simulation and troubleshooting
RT-to-RT transfer testing
Compatibility & Integration The BUS-68005 interfaces with test systems and production environments through RS-232, IEEE-488 (including DMA), and parallel I/O connectivity, enabling integration into automated test sequences.
DDC BUS-68005 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the DDC BUS-68005. Calibration covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common DDC BUS-68005 faults: power supply failure (cRIO-9073/9074), C-series slot connector wear, PXI chassis fan failure, GPIB interface failure on VXI controllers, BIOS/EEPROM corruption. NI CompactRIO most common faults are power supply failure on older cRIO-9073/9074 chassis and C-series module slot connector wear from repeated hot-swap cycles. PXI chassis fan failure is the most common wear item — chassis fans are field-replaceable. VXI embedded controllers most commonly develop EEPROM corruption and GPIB interface failure.

This DDC BUS-68005 is listed at $3,200. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
DDC BUS-68005 calibration cost
NIST-traceable calibration for the DDC BUS-68005 is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. Turnaround is 1 to 3 business days after receipt. See full calibration details →
