AT1032S Test Sequencer Applications

The AT1032S is a versatile test sequencer designed to streamline and automate testing across a wide range of applications, and over all design stages, from early prototyping to production testing. This page showcases typical use cases where the AT1032S excels.

PCB Functional Testing​

End-of-Line Testing​

Automate comprehensive testing of assembled PCBs before they leave your production line. The AT1032S can validate digital circuits, analog signals, communication interfaces, and power consumption in a single test sequence.

Typical Test Scenarios:

  • Verify proper voltage rails across the board
  • Test digital I/O functionality at various logic levels (1.0V, 1.8V, 3.3V, 5V, even 24V logic level).
  • Stimulate the circuit with specific voltage patterns
  • Validate analog sensor outputs
  • Check I2C/SPI device responses
  • Measure quiescent and active current consumption

Benefits:

  • Reduce test time from minutes or hours to seconds
  • Eliminate human error with automated scripts
  • Generate detailed test reports automatically and/or feed test results to your dashboard
  • Achieve 100% test coverage consistency

Bring-Up and Debug​

When debugging a new PCB design, the AT1032S serves as a powerful multi-function tool that combines the capabilities of multiple instruments.

Use Cases:

  • Apply controlled power while monitoring current draw
  • Stimulate inputs and observe outputs in real-time
  • Inject test patterns via communication buses
  • Isolate faulty sections using relay-controlled signal routing
  • Log long-term behavior (voltages, currents, communication responses)for intermittent issue detection

Bed-of-Nails Testing​

The AT1032S can serve as the controller for custom bed-of-nails test fixtures.

Advantages:

  • 32 I/Os provide comprehensive coverage
  • Relay-switched test points for routing flexibility
  • Built-in current measurement for short detection
  • Programmable power supply for device under test

Capabilities:

  • Coordinate probe positioning (via external motion controllers)
  • Perform measurements at designated test points
  • Generate test reports with spatial information
  • Adapt to different board designs quickly

System Integration Testing​

Multi-Board System Validation​

For systems consisting of multiple interconnected PCBs, the AT1032S can orchestrate complex test sequences that validate inter-board communication and system-level functionality.

Example Scenarios:

  • Test communication between main controller and peripheral boards
  • Simulate external sensors and actuators
  • Verify system response to various input conditions
  • Validate power sequencing across multiple boards
  • Monitor system behavior under different load conditions

Advanced Features:

  • Daisy-chain multiple AT1032S units for expanded I/O coverage
  • Synchronize actions across devices for precise timing
  • Integrate with external equipment (oscilloscopes, spectrum analyzers) via scripting

Production Line Integration​

The AT1032S integrates seamlessly into automated production lines, communicating with other equipment and factory systems.

Integration Points:

  • Connect to MES (Manufacturing Execution Systems) via Ethernet
  • Trigger test sequences based on external signals (barcode scanners, PLCs)
  • Report test results to databases in real-time
  • Control upstream/downstream equipment via dry contact relays
  • Implement pass/fail routing with visual and audible indicators

Communication Protocol Testing​

Multi-Protocol Validation​

With support for CAN, RS232, RS485, I2C, SPI, UART, and Ethernet, the AT1032S can validate complex communication scenarios.

Test Scenarios:

CAN Bus Testing​

  • Monitor bus loading and timing

RS485 Multi-Drop Networks​

  • Test communication with multiple slave devices
  • Verify collision detection and resolution
  • Validate long-distance communication
  • Check termination and biasing

I2C/SPI Device Communication​

  • Scan for I2C devices on the bus
  • Read/write to specific registers
  • Verify data integrity
  • Test clock stretching and multi-master scenarios

Protocol Conformance Testing​

Ensure your device's communication implementation meets protocol specifications.

Testing Capabilities:

  • Generate edge cases and error conditions
  • Verify timing requirements
  • Test error recovery mechanisms
  • Validate protocol state machines

Environmental and Stress Testing​

Temperature and Environmental Testing​
