Production Measurement System Capabilities

• Product is a integrated sensor and transparent
  path for Tx/Rx parametric tests
• For example BERT tests, or Power Spectral Mask
• Product is a complete measurement system for Tx
  power calibration/testing
• EIRP, TRP
• Verify correct assembly with Near Field or Far
  field test results
• Compare NF scans with reference signatures
• Validate correct operation of Phased Array(eg.
  MIMO) Products
• Look at NF amplitude and phase signatures vs a
  reference for a test sequence
• Capture changing TRP values with antenna and
  phase shifting and compare
• with an anticipated reference signature
• Test all embedded antennas in a multi antenna
  solutions over the air , quickly
