Bench testing power supply accessories connect test instruments to the device being monitored or tested. Bench test leads and patch cords connect to testing and measuring devices, or extend reach and measurement range. Bench test clips, probes, and connectors touch or connect a meter to the device under test, or extend the reach of the test leads. BNC adapters are commonly used with coaxial cables in commercial and industrial settings. RF adapter kits adapt an existing system from one connector type to connect it to a different connector type. SMA adapters and terminations convert RF cabling to make system components compatible for a stable, non-permanent connection. Test lead holders facilitate mounting to offer a safe place for bench test lead storage.
