Overview

Product overview

Key product information and technical features.

This cable provides a custom-connection alternative to VHDCI-to-VHDCI cabling. Its flying leads let users connect individual signals to a breakout fixture rather than use a standard VHDCI accessory.

Each digital waveform generator/analyzer signal breaks out into separate signal and ground receptacles. With a supported instrument, this arrangement supports logic-analyzer-type connections and stimulus/response testing.

Paired signal and ground leads help preserve signal quality.
Individually shielded micro-coaxial construction with shielding on the complete cable assembly.
Wire mapping is printed on the lead pairs for connection identification.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

What is the cable's manufacturer part number?

NI identifies the 1.5 m SHC68-H1X38 cable as part number 192681-1R5. The other items listed on its product page, 194096-01 and 779581-01, are accessory sets rather than alternative cable part numbers.

How do the flying leads connect to a fixture?

Each signal breaks out into two 0.1-inch header receptacles: one for the signal and one for ground.

Does NI publish a temperature rating for the complete cable?

NI does not publish a single temperature specification for the complete assembly. Individual wire or sleeving ratings must not be treated as the cable assembly's operating range.
