Object
This attribute is the name of the file with the Spectrum Analysis data
at the CMTS that is to be downloaded using TFTP to the PNM server.
This value can only be changed while a test is not in progress. An attempt
to set this value while the value of 'docsPnmCmtsUsSpecAnMeasStatus' is
'busy' will return 'inconsistentValue'.
If the value of this object is the DEFVAL (empty string), then a default
filename value will be used. Otherwise the value set will be used as
the filename.
If a default filename value is used, it is generated as the test name
plus a unique CCAP identifier (either a loopback address (IPv4 or IPv6)
or FQDN), plus the 'epoch time'. The epoch time (also known as 'unix time')
is defined as the number of seconds that have elapsed since midnight
Coordinated Universal Time (UTC), Thursday, 1 January 1970.
Hence, the format would be:
PNMCcapSpecAn_<Unique CCAP Identifier>_<epoch>
For example: PNMCcapSpecAn_ccap1.boulder.cablelabs_1403405123
The data file is comprised of a header plus the Spectrum Analyzer Data.
The header is comprised of ordered fixed-length fields. Unless
otherwise specified, the header fields contain hex values that are
right-justified within the field. If necessary the field is left-padded
with zero values.
Syntax of the file is as follows:
File Type set to '504E4D6A' (without the quotes) 4 bytes
Capture Time 4 bytes
ifIndex 4 bytes
Unique CCAP ID 256 bytes
Center Frequency in Hz 4 bytes
Frequency Span in Hz 4 bytes
Number of Bins 2 bytes
Length in bytes of Spectrum Analysis data 4 bytes
Spectrum Analysis Bin Amplitude Data BinAmplitudeData
