is the power level measurement data filename with a limit of 20
characters excluding the "

Displaying FFT Power Level Measurement Data
The fft display command is used to display FFT power level measurement data. The
command provides the following FFT data retrieval options:
■
Retrieving FFT Data from an Operational CMTS Module
■
Retrieving FFT Data from a File System
The FFT data can be processed into a table or graph format and then displayed to a
console or telnet session.
Retrieving FFT Data from an Operational CMTS Module
Power level measurement data can be directly retrieved from an operational CMTS
module. Use the
fft display command, in Privileged EXEC mode, to retrieve FFT
data from a CMTS module, as follows:
MOT#
fft display {<
Slot
/
Port>
} startfreq {<
0-81920000
>} endfreq
{<
0-81920000
>} { table | graph }
where:
Slot
is always 0 for the BSR 2000.
Port
is a valid upstream port number.
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.
Retrieving FFT Data from a File System
Power level measurement data can be retrieved from a file system if a user has saved
the latest FFT power level measurement data to a file system with the
fft store
command. See Storing FFT Power Level Measurement Data .
Use the fft display command, in Privileged EXEC mode, to retrieve FFT power level
measurement data from a file system, as follows:
MOT#
fft display { nvram: <
WORD
> | flash: <
WORD
>} startfreq {<
0-81920000
>}
endfreq {<
0-81920000
>} { table | graph }
