WiMAX, WiBro Measurements (Options K92/K93)
The WiMAX IEEE 802.16 OFDM, OFDMA Measurements option (R&S FSL–K93) extends the
functionality of the R&S FSL to enable WiMAX IEEE 802.16e, WiBro Measurements according to the
IEEE standards listed below. It includes the functionality of the WiMAX 802.16 OFDM Measurements
option (R&S FSL–K92). Accordingly both options are described together in this section, differentiated by
the corresponding standards:WiMAX 802.16 OFDM Measurements (R&S FSL–K92/K93)
– IEEE 802.16–2004/Cor 1–2005 OFDM physical layer mode
The short forms IEEE 802.16–2004 OFDM is used in this section to reference this standard.
The corresponding remote control mode is OFDM.
• WiMAX IEEE 802.16 OFDM, OFDMA Measurements option (R&S FSL–K93)
– IEEE 802.16–2004/Cor 1–2005, IEEE 802.16e–2005 OFDMA physical layer mode
The short form IEEE 802.16e–2005 OFDMA is used in this section to reference this standard.
The corresponding remote control mode is OFDMA.
– IEEE 802.16–2004/Cor 1–2005, IEEE 802.16e–2005 based WiBro
The short form IEEE 802.16e–2005 WiBro is used in this section to reference this standard.
The corresponding remote control mode is WiBro.
The options are available from firmware version 1.40 (R&S FSL–K92) and 1.50 (R&S FSL–K93).
TX measurements of a WiMAX Device Under Test (DUT) according to the standards specified for the device
are performed:
• Modulation formats
– IEEE 802.16–2004: BPSK (IEEE 802.16–2004 OFDM), QPSK, 16QAM, 64QAM
• Modulation measurements
– Constellation diagram
– Constellation diagram per OFDM carrier
– I/Q offset and I/Q imbalance
– Carrier and symbol frequency errors
– Modulation error (EVM) per OFDM carrier or symbol
– Amplitude response and group–delay distortion (spectral flatness)
• Amplitude statistics (CCDF) and crest factor
• Frequency and Phase error vs Symbol
• Transmit spectrum mask
• Adjacent Channel Power (absolute and relative)
• FFT, also over a selected part of the signal, e.g. preamble
• Payload bit information
• Capture time selectable up to 50 ms, multiple sweeps possible for large number of bursts
