3.9.2.1 Result display for measurements on OFDM signals
Fig. 3-12: Result summary list for measurements on OFDM signals
●
EVM All Carr, IEEE802.11a, j, g, p
Shows the EVM (Error Vector Magnitude) over all carriers of the payload symbols
in % and in dB. For better orientation, the table also shows the corresponding limits
specified in the standard.
●
EVM Data Carr, IEEE802.11a, j, g, p
Shows the EVM (Error Vector Magnitude) over all data carriers of the payload sym-
bols in % and in dB. For better orientation, the table also shows the corresponding
limits specified in the standard.
●
EVM Pilot Carr, IEEE802.11a, j, g, p
Shows the EVM (Error Vector Magnitude) over all pilot carriers of the payload sym-
bols in % and in dB. For better orientation, the table also shows the corresponding
limits specified in the standard.
●
IQ Offset, IEEE802.11a, j, g, p
Shows the IQ offset of the signal in dB. This is the transmitter center frequency
leakage relative to overall transmitted power. For better orientation, the table also
shows the corresponding limits specified in the standard.
●
Gain Imbalance, IEEE802.11a, j, g, p
