Syntax Description

{receivedPower} | {gainSettingsIF} | {gainSettingsRF}}>
in (Interference + Noise) The interference + noise power levels are computed by the
hardware on a burst-by-burst basis.
NoteThis parameter is available for a dual antenna system only.
inr (Interference + Noise Ratio) The ratio of the interference + noise power levels
captured by the first antenna to the second antenna on a burst-by-burst basis. This
value is specified as a log to base 2 number.
constVariance (Constellation Variance) The average energy of the constellation error signal - the
error between the received (noisy) constellation symbol and the nearest ideal
constellation symbol. Constellation Variance is a measure of the Signal to
Interference + Noise ratio (SINR) for that tone. On a single antenna system, it
represents 1/SINR. On a dual antenna system, it represents a composite value
providing 1/SINR.
timingOffset Represents the histogram of timing delay variations detected in the radio link.
freqOffset This represents the frequency offset calculations made to keep the receive frequency
on a slave radio synchronized with the master radio.
syncStatus Represents the synchronization status.
receivedPower A measure of the analog signal power received by the radio system on a
burst-by-burst basis.
gainSettingsIF Represents the changes in the automatic gain control loop maintained by the
hardware. This may be captured for each antenna and for the intermediate frequency
(IF) module.
gainSettingsRF Represents the changes in the automatic gain control loop maintained by the
hardware. This may be captured for each antenna and for both the intermediate
frequency (IF) and radio frequency (RF) modules.
totalGain Represents the changes in the automatic gain control loop maintained by the
hardware. This can be captured for each antenna.
