The analyzer makes OFDM measurements of the modulated signal in accordance with IEEE 802.16-2004.
As a result of measurements, you receive the following data:
- EVM measurements
—EVM all carriers
—EVM data carriers only
—EVM pilot carriers - IQ constellation (scalar results) — IQ offset
—Gain imbalance
- quadrature offset - power measurement
— power burst
— Crest factor - symbol clock error (scalar result)
- CINR
- RSSI
Graphically displayed:
- EVM measurements
— EVM vs. symbols
EVM vs. carrier - frequency error vs preamble
- phase error vs preamble
- Spectrum flatness
— Adjacent carrier power difference - group delay
- Constellation diagram (color coded according to modulation
- Bit stream (color coded according to modulation)
- Spectrum emission mask (IEEE, ETSI)
- Adjacent channel power (absolute and relative) with noise correction
- CCDF measurement
Also possible:
- Burst summary list (listing of EVM and power of all bursts)
- Seamless capture
- automatic demodulation
- Remote Control via GPIB or LAN
- Export and import of IQ data, recalculation of data
