Portable Intermittent Fault Detector™ (PIFD™)

The portable IFD is capable of interfacing with 128, 256, or 512 electrical connection points. The portable IFD is a patented diagnostic instrument that can simultaneously and continuously monitor all unit under test (UUT) circuits, individually at the same time, detecting intermittent faults that occur, even as short as *50 nanoseconds (0.00000005 seconds) in duration.

In addition to detecting and isolating intermittent faults, the portable IFD AutoMap feature will automatically interrogate and store the as-designed wiring configuration for a good unit and then based on that “gold” configuration, detect any open, short, ohmic, impedance, drift or mis-wiring problem in subsequent UUTs.

Features

• Portable unit utilized on/off platform to test wiring to relays, circuit breakers, connectors, and ribbon-cables
• Rapidly detects and isolates permanent and intermittent shorts, opens, instability and EMI events
• Rapid set-up with powerful test software
• Quick testing: results displayed real-time
• Available with 128, 256, or 512 test points
• Detects and isolates permanent and intermittent shorts, opens, instability and Electromagnetic Interference (EMI) events
• Rapid set-up with powerful test software
• Quick testing: results displayed real-time

Functions

• Intermittency – detected to less than *50ns on every test point individually, simultaneously and continuously
• Continuity – programmable continuity checks against referenced values
• Log Scope – instant display of a circuits or component’s stability
• Shorts – two modes providing shorts indication and shorts tracing capability
• Analyze – provides an impedance signature for the Unit Under Test
• AutoMap – rapid mapping of circuits for complex and/or ad-hoc testing

Benefits

• IFD eliminates:
  • Repeated returns of the same assembly for repair
  • Excessive spare part stock to cover units out of service
  • Downtime to replace units
  • Scraping costs associated with unrepairable units
  • Wasted test time using technology that cannot detect intermittent faults
• Reduces No Fault Found (NFF), Can Not Duplicate (CND), Re-Test OK (RTOK), No Evidence of Failure (NEOF)
• Reduces life-cycle support costs
• Increases operational availability, asset availability, and mission capable rates
• Compliance with US Department of Defense (DoD) MIL-PRF-32516 for electronic test equipment, intermittent fault detection and isolation for chassis and backplane conductive paths and their associated wiring harnesses
