Description
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. Existing NBM probes can also be used with the A/D Probe Converter and the Digital Broadband Probe Repeater.
Highlights
- Digital probe interface, therefore no calibration of the measuring device necessary
- All NBM probes can be used with the A/D probe converter
- Digital Broadband Probe Repeater converts the digital electrical signal into an optical signal
- Precise and direct measurements with the live measurement option for Narda TSX
Digital probes
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.
