56Operating Manual 1176.7649.02 ─ 04
Shows the gain imbalance of the signal in % as well as dB. This is the amplification
of the quadrature phase component of the signal relative to the in-phase compo-
nent.
●
Quadrature Error, IEEE802.11a, j, g, p
Shows the quadrature error of the signal in degree. This is the deviation of the
quadrature phase angle from the ideal 90°.
●
Frequency Error, IEEE802.11a, j, g, p
Shows the frequency error between the signal and the current center frequency of
the R&S analyzer. The absolute frequency error is the sum of the frequency error
of the R&S analyzer and that of the DUT. If possible, the transmitter and the
receiver should be synchronized.
For better orientation, the table also shows the corresponding limits specified in the
standard.
●
Symbol Clock Error, IEEE802.11a, j, g, p
Shows the clock error between the signal and the sample clock of the R&S ana-
lyzer in parts per million (ppm). For better orientation, the table also shows the cor-
responding limits specified in the standard.
●
Burst Power, IEEE802.11a, j, g, p
Shows the mean burst power in dBm.
●
Crest Factor, IEEE802.11a, j, g, p
Shows the crest factor in dB. The crest factor is the ratio of the peak power to the
mean power of the signal (also called Peak to Average Power Ratio, PAPR).
