The Nautel RF Current Probe is an in-line probe designed to facilitate the measurement and provision of a representative sample of the RF current for LF/MF Non-Directional Radio Beacons, LF/MF DGPS systems and MF Navtex Systems.
The probe provides a 1V:1A sample which is useful for performance, testing and maintenance of LF/MF Non-Directional Radio Beacon, LF/MF DGPS systems and MF Navtex systems.
The probe has an in-line coaxial input for connection between the transmitter and a resistive (dummy) test load. The probe also contains a through hole input for measurement of RF current in wires.
- Standard Interface Connections.
- NDB System Measurement Capabilities.
The RF current probe uses standard Type ‘N’ RF connectors for the connections between the transmitter and resistive (dummy) test load. Alternatively an insulated through hole path is available for measurement of RF current in wires. The output sample from the probe is via a standard BNC RF connector.
The RF Current Probe can be used as a reliable means to verify a variety of parameters for LF/MF Non-Directional Radio Beacon Systems, LF/MF DGPS systems and MF Navtex systems which includes the Forward Power, Antenna Current and System Harmonics. The probe provides a 1V:1A sample representative of the RF Current passing through the RF Current probe. This sample can be measured using a RF voltmeter or oscilloscope and used to calculate the output power of the transmitter if the resistance of the test load is known. Antenna current can also be measured in the antenna tuning unit. The 1V:1A sample can also be used via the appropriate attenuation to measure the system harmonic levels at the ATU.
Please consult the factory for assistance with the proper placement of the RF Current probe in the ATU and with measurement techniques for harmonics and antenna current in LF/MF Non-Directional Radio Beacon Systems, LF/MF DGPS systems and MF Navtex systems.
