91550-1L Current Probe
Current Probes are a diagnostic tool for cable common mode current sources of radiated emissions and as measurement of cable common mode coupled currents during radiated susceptibility testing. The Model 91550-1L Probe has an extremely broad frequency range, covering 20 Hz to 100 MHz and calibration available down to 20 Hz, which makes it ideal for MIL-STD-462 CEO1 and RSO1.

A Diagnostic Probe for Radiated Emissions with a Broad Frequency Range
Current Probes are a diagnostic tool for cable common mode current sources of radiated emissions and as measurement of cable common mode coupled currents during radiated susceptibility testing. The Model 91550-1L Probe has an extremely broad frequency range, covering 20 Hz to 100 MHz and calibration available down to 20 Hz, which makes it ideal for MIL-STD-462 CEO1 and RSO1. In particular, the newer CEO1 limits which are dependent on EUT current/voltage requirements are more stringent than the older fixed limit CEO1 requirement. Coupled with the widespread use of microwave spectrum analyzers (Keysight PXA).
The 91550-1L has 3.18 cm (1.25 in) window, making it 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).
