The NI SHC68-H1X38 is a shielded VHDCI single-ended flying-lead cable that connects National Instruments digital waveform generator/analyzer devices to custom breakout fixtures, header pins, and external circuits. At 1.5 meters in length, this cable enables both pattern generation and acquisition in data acquisition, instrumentation, and stimulus-response testing environments.
Technical Specifications
• Cable Type: Shielded micro-coaxial construction
• Length: 1.5 meters (4.9 feet)
• Characteristic Impedance: 50 Ω
• Front-End Connector: 68-pin Male VHDCI
• Back-End Connector: 76-pin Female Flying Leads
• Signal Architecture: Paired signal and ground lines per channel with 0.1-inch pitch compatible receptacles
– Key Features
• Shielded design minimizes noise and electromagnetic interference during signal transmission
• Flying leads enable direct interfacing with circuit boards and custom fixtures without additional connectors
• Paired signal/ground configuration preserves signal integrity across all channels
• 50 Ω impedance matching optimizes compatibility with NI digital signal sources
• Each flying-lead pin breaks out to dedicated signal and ground receptacles
– Typical Applications
• Data acquisition and high-speed digital instrumentation
• Logic analyzer-type measurements
• Simultaneous stimulus-response pattern generation and acquisition
• Custom circuit and device interfacing
• Testing and signal analysis
– Compatibility & Integration
This cable interfaces directly with NI 6535, 6536, and 6537 digital instruments; NI 654x, 655x, and 657x series digital waveform generator/analyzer modules. The 68-pin Male VHDCI connector mates with standard NI device front panels, while the 76 flying leads accommodate flexible backplane connections to 0.1-inch pitch header receptacles.
