The analyzer measures the OFDM modulated signal in accordance with IEEE 802.16-2004.
As a result of measurements, you receive the following data:
- Measurement of EVM
– EVM all carriers
- EVM data carriers only
– EVM pilot carriers - Constellation IQ (Scalar Results) – Shift IQ
– Gain imbalance
– Quadrature shift - Power measurement
- Power burst
– Crest factor - Symbol clock error (scalar result)
- CINR
- rssi The following is displayed graphically:
- Measurement of EVM
– EVM vs symbol
– EVM vs carrier - Frequency vs preamble error
- Phase error vs preamble
- The uniformity of the spectrum
is the power difference of the adjacent carrier - group delay
- Constellation diagram (color-coded according to modulation
- Bitstream (color coded according to modulation)
- Spectrum emission mask (IEEE, ETSI)
- Adjacent channel power (absolute and relative) with noise correction
- CCDF measurement
Also possible:
- Package Summary List (EVM and Power of All Burst List)
- Seamless capture
- Automatic demodulation
- Remote Control via GPIB or LAN
- Export and import of IQ data, recalculation of data
