Available Features (802.16 OFDM)

The following features are available with OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. Demodulation:

Standard 802.16 OFDM demodulation presets
Variable carrier spacing
Pulse Search with manual override
IQ Meas constellation measurement data (includes multiple formats when present)
Auto detected format: BPSK Binary phase shift keying - A type of phase modulation using 2 distinct carrier phases to signal ones and zeros., QPSK Quadrature phase shift keying, 16QAM, 64QAM (color coded for display)
FDD Frequency Division Duplex: A duplex scheme in which uplink and downlink transmissions use different frequencies but are typically simultaneous., TDD Time Division Duplex: A duplexing technique dividing a radio channel in time to allow downlink operation during part of the frame period and uplink operation in the remainder of the frame period. and H-FDD modes (including non-bursted)
Subchannelization supported
Equalizer response measurement data
Common Pilot Error measurement data
Enhanced Error Vector trace data display
Mirrored (flipped) frequency spectrums used to remove the effects of high-side mixing or complex conjugation mismatches in simulated data.
Measurement offset and interval (similar to time gating) used to select specific data segments for analysis
Averaging is applicable only in the following circumstances:
- Multi-measurement averaging is available for OFDM RMS Error Vector Spectrum trace data
- The following averaging types are available for the numeric error summary data and for the pre-demodulated spectrum trace data:
  - RMS (video)
  - RMS Exponential
  - Continuous Peak Hold
Time gating is not available (does offer measurement offset/interval feature)
CCDF of the 802.16 OFDM burst
Preamble Frequency Err (used to show frequency settling)
Subframe Info trace data

These features are available with Digital Demod but not available for OFDM Demodulation:

IQ Mag error and IQ Phase error trace data
