Electromagnetic Wave Emission Pattern Measurement System – MRP770

• Spectrum analyzer
  Measure the signal that is actively radiated from the EUT.
  It is mainly used for measuring wireless modules.
• Network analyzer
  Input a signal to the EUT and measure the signal radiated from the antenna.
  Mainly used to measure passive sources such as antennas.
• Signal generator
  Input a signal to the EUT and measure the signal radiated from the antenna with a spectrum analyzer.
  Mainly used to measure passive sources such as antennas.

PC software for automatically measuring the radiation pattern of horizontal or vertical polarization.

Setting screen

Set the spectrum analyzer, network analyzer, and electric turntable. You can also save and read the set values.

• Vertical axis
  Set the reference level and display scale.
• Horizontal axis
  Set the measurement point, center frequency, and frequency span.
• Measurement function
  Set the averaging count.
• Marker
  You can specify a maximum of 5 points for the marker within the set frequency span range.
• Turntable
  • Specify the measurement start position and end position in steps of 1 degree.
  • The rotation step interval is at least 1 degree.
  • Set the waiting time in ms unit until the angle to be measured is reached and the spectrum analyzer measurement is started.
  • Set the measurement direction to either one-way (CCW) or round-trip (CCW+CW).

Measurement screen

Turn the turntable to the specified angle and perform sweep measurement with the spectrum analyzer. Automatically plot the signal level at the specified frequency on the polar graph.

• Horizontal polarization and vertical polarization are measured separately, and the measurement results are displayed on the same GUI.
• Displays the measured, maximum, and average values for both horizontal and vertical polarization.
• Measurement data can be output as a CSV file.
• The unit of measurement of the polar coordinate graph can be switched between absolute value display (dBm) and relative value display (dB). The relative value display is based on the maximum measured value.

1. Antennas with known gains measure in the boresight direction.
   

   Pt［dBm］	Effective radiated power (ERP)
   Gt［dB］	Antenna gain
   Pt eirp［dBmeirp］	Equivalent isotropically radiated power Pt [dBm] + Gt [dB]
   Pr［dBm］	Received power of RF connector part of Electromagnetic anechoic box through receiving antenna + coaxial cable

2. Find the degree of antenna coupling.
   

   K［dB］

   Pt eirp［dBmeirp］-Pr［dBm］

3. Can be measured radiation electricity of measured device (EUT) in reception system same as calibration.
   

   P eirp［dBmeirp］
