Cisco uBR7200 Series Universal Broadband Router Wireless Modem Card and Subsystem Installation and Configuration
78-6030-03
Command Reference
show interfaces radio (histdata)
Use this command in privileged EXEC mode to display the collected histogram data for the identified
histogram specification. The values are displayed as a BinID:Value pair. BinId represents the sample
value contained in that bin. Value represents the count in the histogram bin.

Syntax Description
slot Positive integer representing the Cisco uBR7200 series slot number.
port Positive integer representing the port number on that slot.
statParam {in | inr | constVariance | timingOffset | freqOffset | syncStatus | receivedPower
| gainSettingsIF | gainSettingsRF | totalGain | codewordError}
The radio attribute whose data is to be collected as a histogram.
Note If <statParam> is specified, antenna_num is conditionally required.
in (Interference + Noise) The interference plus noise power levels are computed by
the hardware on a burst-by-burst basis.
inr (Interference + Noise Ratio) The ratio of the interference plus 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.
Note This parameter is available for a dual antenna system only.
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 (SINR)
–1
. On a dual antenna system, it represents a composite value
providing (SINR)
–1
.
timingOffset Represents the timing delay variations detected in the radio link.
freqOffset Represents the carrier frequency offset between the slave radio and 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 intermediate frequency (IF) attenuation value commanded by the
automatic gain control loop. This can be captured for each antenna and for the IF
module.
