Syntax Description
threshParam <{{in} | {inr} | {constVarience} | {timingOffset} | {freqOffset} | {syncStatus} |
{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.
constVarience (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 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.
