Narda Digital Broadband Probe Repeater

Narda Digital Broadband Probe Repeater Overview

Narda’s Digital Broadband Probe Repeater transforms the digital electrical signal from a connected FieldMan broadband probe into an optical signal. This signal is then conveyed to the FieldMan EMF Meter through a fibre optic cable, allowing for interference-free measurements over distances of up to 50 metres. The housing of the repeater has an IP54 rating and boasts a high irradiation resistance of over 1000 V/m, making it suitable for outdoor use and measurements at extremely high field strengths where human presence is not permitted.

The digital interface of the FieldMan probes ensures that the measurement data is transmitted to the repeater without any interference, which means the basic device does not need to be calibrated. The probe extension is ergonomic for comfortable long periods of use with a long battery life of up to 130 hours as well as a convenient universal USB-C charging interface.

In addition to HF broadband FieldMan probes, NBM probes can also be connected with the help of an additional A/D probe converter.
