Applications

Signal Integrity for Measurement

RF & Microwave Test

Challenge: VSWR and phase stability drive measurement accuracy.

  • SMA / N-type equivalents
  • Phase-stable coax
  • Low-VSWR terminations

DC–18 GHz · VSWR < 1.3

ATE & Bench Instruments

Challenge: High channel counts need reliable, repeatable connections.

  • D-sub / BNC equivalents
  • Custom breakout harnesses
  • Shielded pairs

Low-leakage · shielded

Sensor & DAQ

Challenge: Low-level signals require low-noise cabling.

  • Triaxial / low-noise coax
  • Twisted shielded pairs
  • Guarded constructions

Low-noise · guarded

Lab & Calibration

Challenge: Repeatable, durable, cleanable connections.

  • Precision connectors
  • Durable jackets
