Antenna pattern testing in seconds

The RFX is a compact bench-top scanner that characterizes antennas in your own lab environment in real-time. RFX provides far-field patterns, bisections, EIRP and TRP in seconds. Novel near-field results, including amplitude, polarity and phase give insights into the root causes of antenna performance challenges and help troubleshoot far-field radiation patterns.



    Key Features & Functions

    • 300 MHz - 6 GHz
    • 384 H-field probes
    • Maximum radiator size: L 16 cm x W 10 cm (L 6.30” x W 3.94”) real-time scanning
    • Far-field resolution: 1.8° for theta and 3.6° for phi

  • Frequently Asked Questions

    1. How do you provide an accurate EIRP estimate despite the fact that only one side of DUT is measured?  
    2. How fast is the full measurement cycle?  
    3. When measuring GSM power, how do we address duty cycle?  
    4. How do we measure transmitters with rapidly changing power levels?  
    5. What is the measurement sensitivity for accurate power measurements?  
    6. Are the measurements reliable in noisy ambient environments without an anechoic enclosure?  
    7. Can you measure multiple antennas on different planes?  
    8. What kind of power supply can be used?  
    9. What is the range of supported power levels?  
    10. Where do I place the DUT?  
    11. What is the accuracy of RFxpert measurements?  
    12. I have a network analyzer that is not on the list of supported analyzers, can it still be supported?  
    13. What are the minimum system requirements?  
    14. What is the maximum power level that RFxpert can receive without being damaged?  
    15. What are the effects on the measurement from driving the antenna with lower power (e.g. dBm vs. 20 dBm)?  
    16. The features/specifications indicate measuring dipoles and helical antennas. I assume that this is done by laying the DUT flat on the scanner bed? How do you feed the antenna without having the cable on the scanner bed, without some sort of de-embedding? Both of these conditions would seem to compromise the integrity of the near-field and alter the measurement accordingly.  
    17. When selecting “Pattern Settings Properties”, “Amplitude Scale”, “Comparison Type”, switching from linear to Log10 seems to have no effect. What is this supposed to do? I thought it changed the scale of the near-field and far-field patterns.  
    18. If I put my cell phone on the scanner, does it scan?  
    19. How can I measure each side of the DUT in order to get a full spherical pattern?  
    20. Can RFxpert be integrated into existing test applications or simply automated to provide faster measurement results?  
    21. Why am I getting low power warning? How can I test an antenna while getting low power warning?  
    22. What is the resolution bandwidth of Rfxpert?
