Attribute Meaning
Wireless Link
Status
As the attribute name suggests it displays the current status
of the wireless link. A state of ‘Up’ on a green background
indicates that a point-to-point link is established. A state of
‘Down’ on a red background indicates that the wireless link is
not established.
Maximum
Transmit Power
The maximum transmit power that the local wireless unit is
permitted to use to sustain a link.
Remote Maximum
Transmit Power
The maximum transmit power that the remote wireless unit is
permitted to use to sustain a link.
Transmit Power Transmit power histogram is expressed in dBm and
presented as: max, mean, min, and latest. 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
pag
e 7-19.
Receive Power Receive power histogram is expressed in dBm and presented
as: max, mean, min, and latest. 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 7-19.
Vector Error The vector error measurement compares the received
signal’s In phase / Quadrature (IQ) modulation characteristics
to an ideal signal to determine the composite error vector
magnitude. The results are stored in an histogram and
expressed in dB and presented as: max, mean, min and latest.
The max, min and latest are true instantaneous
measurements; the mean is the mean of a set of one second
means. The expected range for Vector Error would be
approximately -1.5 dB (NLOS link operating at sensitivity
limit on BPSK 0.50) to –28 dB (short LOS link running
64QAM 0.83). See Histogram data on page 7-19.
