System histograms
The System Statistics page contains the following fields under System Histograms:
Transmit Power
Receive Power
Vector Error
Link Loss
Signal Strength Ratio
The Signal Strength Ratio is the ratio of the power received by the Vertical /
Horizontal receivers and presented as: max, mean, min, and latest in an histogram
format. The max, min and latest are true instantaneous measurements; the mean is the
mean of a set of one second means. See Histogram data on
page 6-18.
Transmit Data Rate
The data rate in the transmit direction, expressed in Mbps and presented as: max,
mean, min, and latest in an histogram format. The max, min and latest are true
instantaneous measurements; the mean is the mean of a set of one second means.
Expected data rates can be found in Data rate calculations on
page 4-99.
Receive Data Rate
The data rate in the receive direction, expressed in Mbps and presented as: max,
mean, min, and latest in an histogram format. The max, min and latest are true
instantaneous measurements; the mean is the mean of a set of one second means.
Expected data rates can be found in Data rate calculations on
page 4-99.
Aggregate Data Rate
The sum of the data rate in the directions expressed in Mbps and presented as: max,
mean, min, and latest in an histogram format. The max, min and latest are true
instantaneous measurements; the mean is the mean of a set of one second means.
Expected data rates can be found in Data rate calculations on
page 4-99.
Histogram Measurement Period
The time over which the system histograms were collected.
