Test Accessories & Cables

Test accessories and cables are the essential supporting components that enable accurate, safe, and reliable measurements across all categories of test and measurement instrumentation. This category encompasses a wide variety of supplementary items including RF cables, test leads, probe adapters, test fixtures, signal connectors, batteries, and mechanical accessories such as hand pumps and carrying cases. Selecting the correct accessory is critical to measurement integrity — a poorly matched cable or adapter can introduce impedance mismatches, signal degradation, or safety hazards.

From precision RF interconnects used in microwave testing to pneumatic and hydraulic pumps used in pressure calibration, test accessories bridge the gap between instruments and the systems under test. Batteries and power accessories ensure uninterrupted operation in field environments, while test fixtures and jigs enable repeatable connections for production testing and calibration workflows in electronics manufacturing, power, and process industries.

Typical Applications

RF and microwave signal routing using precision cables and connectors in laboratory and production environments
Pressure calibration with pneumatic and hydraulic hand pumps for process instruments
Battery replacement and power management for portable field instruments
Test fixture and jig setup for automated production testing
Probe and adapter selection for oscilloscopes, multimeters, and impedance analyzers
