Narda EF 5092 50 GHz Electric field Probe for NBM Meter

The Narda EF 5092 50 GHz Electric field Probe for NBM Meter contains three orthogonally-arranged thermocouple sensors. Each sensor consists of several thermocouples, which together form a dipole. The output voltage from the thermocouple is proportional to the coupled power level, regardless of the signal shape. The isotropic measurement value is obtained by addition within the probe.

The Narda EF 5091 probe detects electric fields from 300 MHz to 50 GHz, covering the fields found in satellite communications and radar equipment. The use of thermocouples naturally results in a true RMS reading, making the probe particularly suitable for measuring human safety limit values in a multi-frequency environment.

The e-field probe is mechanically and electrically robust. The probe head ismade of foam material to provide effective protection for the sensors, while having excellent RF characteristics. The sensors can handle high impulse power levels.

The probe is calibrated at several frequencies. The correction values are stored in an EPROM in the probe and are automatically taken into account by the NBM instrument. Calibrated accuracy is thus obtained regardless of the combination of probe and instrument.
