With the FieldMan, Narda opens up new dimensions in the versatility and handling of electromagnetic field measuring devices. The lightweight and easy-to-use device can be used with different probes and thus allows reliable, direction-independent measurements from 0 Hz (DC) to 90 GHz. The successor to the proven NBM-500 series detects high and low frequency electric and magnetic fields. It delivers precise and reproducible measurements and delivers meaningful and reliable results.
Highlights
- Wide measuring range from 0 Hz (DC) to 90 GHz
- Ambient sensors store temperature, humidity, measuring altitude and air pressure
- Digital probe interface, therefore no calibration of the measuring device necessary
- Additional input option for data, text, voice, photo or video
A wide range of isotropic field probes are available for the FieldMan. All of them transmit their information and measurement data to the FieldMan as a digital signal, either via an electrical USB interface or via an optical COM interface. In this way, interference is significantly reduced compared to high-impedance analog interfaces. The specially developed screw connectors and electrical contacts are extremely robust and resistant.
The probes are automatically recognized after connection to the FieldMan. Sensors inside the probe record the temperature of the measuring point and transmit it to the FieldMan display. In addition to the automatic offset correction, the temperature measurement is also used to compensate for the typical temperature dependency of the sensor diodes. The advantages are uninterrupted measurements without zero adjustment and higher measurement accuracy over wide temperature ranges.
An automatic self-test function can even detect any errors in the sensor technology, making additional testing with a test generator superfluous. Only the digital probes need to be calibrated. You can continue to use your FieldMan in the meantime. Probes are available for many different applications with the appropriate frequency and level ranges.
