Object
This attribute is the name of the file at the CM which is to be
downloaded by 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 'docsPnmCmDsOfdmRxMerMeasStatus' 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 the CM MAC Address 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:
PNMDsMer_<CM MAC address>_<epoch>
For example: PNMDsMer_0010181A2D11_1403405123
The data file is comprised of a header plus the Subcarrier RxMER 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 '504E4D04' (without the quotes) 4 bytes
Capture Time 4 bytes
DS Channel Id 1 byte
CM MAC Address 6 bytes
Subcarrier zero frequency in Hz 4 bytes
FirstActiveSubcarrierIndex 2 bytes
Subcarrier Spacing in kHz 1 byte
Length in bytes of RxMerData that follows 4 bytes
Subcarrier RxMER Data RxMerData
