Understanding the Measurement Results File

Version:
Last Modified: February 23, 2021

The mmWave OTA Validation Test Software saves your measurement results as a CSV file that you can load into the mmWave OTA Validation Visualizer to visualize the measurements.

Refer to the following list for details about the values of each column in the measurement results file:

  • Azimuth—The specified azimuth.
  • Elevation—The specified elevation.
  • Context— The value of this column is <none>, as it is reserved for future use.
  • Frequency—Frequency in the test.
  • BeamNumber—A customized value based on the antenna plugin.
  • Polarization—The reference plane of the antenna. The value of this column is 0 (Horizontal), 1 (Vertical), or 2 (Combined).

Each of the remaining columns in the measurement results file correspond to a specific measurement.

Measurement results are organized into two different sections in the CSV file: Non-Spatial Data and Spatial Data. The Non-Spatial Data section includes measurement data that is not specific to azimuth or elevation angles, and Spatial Data includes measurement data that is valid at different azimuth and elevation angles.

Refer to the following tables for more information about each measurement.

Table 1. Non-Spatial Data Measurements

ACPUpperTRP Total radiated power of ACPUpper.
ACLRLower Adjacent channel leakage ratio of lower offset.
ACLRUpper Adjacent channel leakage ratio of upper offset.
BeamPeakEVMHorizontal(RMS) RMS of EVMs for the H-Plane at beam peak.
BeamPeakEVMHorizontal(Peak) Maximum of EVMs for the H-Plane at beam peak.
BeamPeakEVMVertical(RMS) RMS of EVMs for the E-Plane at beam peak.
BeamPeakEVMVertical(Peak) Maximum of EVMs for E-Plane at beam peak.
BeamPeakOBW Occupied bandwidth at beam peak.
BeamPeakOBWPower Absolute power, in dBm, of the occupied bandwidth at beam peak.
BeamPeakOBWStartFrequency Start frequency of the occupied bandwidth at beam peak.
BeamPeakOBWStopFrequency Stop frequency of the occupied bandwidth at beam peak.
