The Close Field probes have been specifically designed for use with Spectrum Analysers and other EMC receivers to measure magnetic-field radiation from surface currents, slots, cables, and ICs for EMC diagnostic and troubleshooting measurements.
The unique design of these close field probes results in a high level of electric-field rejection which significantly reduces errors and results in calibrated and repeatable measurements.
The EMC Close field Probes operate from 9 kHz to 30 MHz, the 11940A, from 30 MHz to 1 GHz. Five antenna factors appear on each of the probes for calculating absolute magnetic-field strength (dBµA/m) from the dBµV reading of a spectrum analyser.
These probes are supplied With:
- 2 metre SMA (m) to SMA (m) RG-223 cable
- SMA (f) to Type N (m) adapter
