More InfoQuote

Frequency Range: 1 MHz – 1000 MHz

The 94111-Series probes have a 1.25″ window measurement probe covering the frequency range from 1 MHz to 1 GHz. The 94111-Series is ideal for monitoring injected current on cables during bulk current injection tests such as RTCA/DO-160C Section 20 conducted susceptibility, or MIL- STD-462D test method CS114.

The 94111-Series is part of a state of the art attempt to provide test equipment capable of making bulk current injection measurements up to 1 GHz, vs, the present range of 400 MHz. The present 400 MHz range represents the capability of equipment at the time these standards were formulated.  Another application of an extended range probe such as the 94111-Series is as a diagnostic tool searching for cable common mode current sources of radiated emissions, and as measurement of cable common mode coupled currents during radiated susceptibility testing. The different -X models have different cw and pulsed RF current sensitivity and measurement range.

The 3.18 cm (1.25 in) window makes the Model 94111-Series probe suitable for measurements on most power cables (AWG 4/0 cable, good for several hundred Amps, is 12.7 mm (0.5 in) diameter, exclusive of insulation). Probe saturation current is compatible with the current carrying capacity of wires placed in its window.
