Signal to Noise Ratio Measurement

Signal to Noise Ratio (SNR) measurements using the RF Sentry are performed on a
specified idle Spectrum. The acquired SNR data can be displayed or stored in a file
for on demand diagnostic purposes.
This section describes the following tasks:

Configuring SNR Measurement

The snr setup command can be used to configure the SNR measurement on the
BCM3138/BCM3140 chip set. Use the snr setup command, in Privileged EXEC
mode, to configure SNR
MOT#snr setup {<NUM>{<NUM>}} {<5000000-42000000> |
<5000000-65000000> | <5000000-55000000>} {<5000000-42000000> |
<5000000-65000000> | <5000000-55000000>} {1600000 | 200000 | 3200000 |
400000 | 6400000 | 800000} [equalization {auto | off | on}| ingress-cancel {auto |
off | on} | modulation-type {16qam | auto | qpsk}]

nvram: retrieves the power level measurement data from the NVRAM file
system.
flash: retrieves the power level measurement data from the Flash file system.
WORD is the power level measurement data filename - limit of 20 characters
excluding the ".fft" filename extension.
startfreq 0-81920000 is the start of the frequency range (0 Hz - 81.92 MHz).
endfreq 0-81920000 is the end of the frequency range (0 Hz - 81.92 MHz).
table | graph specifies a table or graph display format.
