The 91550-1 and 91550-1L current probes have a calibration available down to 20 Hz, which makes them ideal test equipment for such test methods as MILSTD-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 with degraded sensitivity below 100 Hz, sensitivity at low audio frequencies is very important. Use of the 91197-1 current probes with the HP8566B allows current measurements below 80 dBA at 20 Hz. This is more than 6 dB below MILSTD-461 and related conducted emission limits, including common mode limits on submarines.
