ETS-Lindgren's 94330-1 Current Probe is a small-sized, lightweight probe featuring a 1.90 cm (0.75 in) window, and covers the frequency range of 10 kHz to 250 MHz. This RF sniffer probe is particularly suitable where permanent or semi-permanent installation of current probes is desired. Such applications might be 6 dB or 20 dB safety margin demonstrations during system-level EMC tests, performed on complete weapon system planes, ground vehicles, or ships. Another application is sensing field-to-cable coupled common mode currents during a low level swept cw scan of a commercial aircraft undergoing FAA certification to the High Intensity Radiated Field RF electromagnetic environment. Probe saturation current is compatible with the current carrying capacity of wires placed in its window.
