   Directional power meters are connected between source and load and measure the power flow in both directions. The power applied to the load and the reflection can thus be measured. Compared to low-cost instruments, power meters like NRT provide a number of benefits: most importantly high measurement accuracy through excellent directivity and a measurement method that determines the average power like a thermal power meter. The instruments thus provide correct measurement results even in case of modulation or in the presence of several carriers. Power Sensors NRT-Z feature low insertion loss, very good matching and excellent intermodulation characteristics: the signal to be measured is virtually unaffected, the sensor is fully transparent.


  • For mobile use, service, development, production and quality management
  • Digital sensor interface
  • Sensor operation directly on PC

   Directional power meters are used to measure power and reflection under operational conditions. Typical applications are in installation, maintenance and monitoring of transmitters, antennas and RF generators in industrial and medical fields.

Direct power monitoring on PC

   This is the most economical way of performing high-precision power and reflection measurements with Power Sensors NRT-Z. Via Interface Converters NRT-Z3 and NRT-Z4, the two sensors can be operated on the serial RS-232 or PC Card interface of any PC. In addition to purely remote-controlled applications, eg power monitoring in transmitter stations and EMC test systems, this solution is ideal where the data are to be collected by a computer. This may be in the development laboratory as well as in the maintenance of base stations, where in addition to power and reflection other parameters have to be measured and recorded.

   A Windows user interface (V-NRT,supplied with the sensors) is available for all these applications. This program allows setting of all the available measurement functions as well as display and storage both of individual results and of whole measurement series.
