RF-E 04 Poll E 30 MHz up to 3 GHz

The electrode on the underside of RF-E 04 probe head detects electrical fields which are decoupled by clocked lines and ICs. The resolution of the probe allows for measurements with a distance from 0,5 to 10 mm above the assembly. The RF-E 04 probe was developed for Langer scanner. The RF-E 04 is a passive near-field probe. In principle it has the same structure as the RF-E 03 and RF-E 09 probes. With its small square electrode surface, the specific source of the electrical interference field can be detected. When measuring, the E-field probe is held above or positioned onto components and printed circuit boards. The near-field probe is small and handy. The upperside is electrically shielded. It has a current attenuating sheath and, therfore, is electrically shielded. It can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The E-field probe does not have an internal terminating resistance of 50 Ω.
