docsIf3CmSpectrumAnalysisCtrlCmdFileName

This attribute is the name of the file containing the spectrum
analysis data.
          
This value can only be changed while a test is not in progress.
An attempt to set this value while the value of MeasStatus 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:
          
       PNMSpecAnData_<CM MAC address>_<epoch>
          
For example: PNMSpecAnData_0010181A2D11_1403405123
          
The data file is comprised of a header plus the Spectrum Analysis
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 '504E4D09' (without the quotes)      4 bytes
Capture Time                                          4 bytes
Channel Id (use zero for this test)                   1 byte
CM MAC Address                                        6 bytes
FirstSegmentCenterFrequency                           4 bytes
LastSegmentCenterFrequency                            4 bytes
SegmentFrequencySpan                                  4 bytes
NumBinsPerSegment                                     2 bytes
EquivalentNoiseBandWidth                              2 bytes
WindowFunction(SpectrumAnalysisWindowFunction enum)   2 bytes
Length in bytes of SpecAnData that follows            4 bytes
Spectrum Analysis Data                   BinAmplitudeFileData
          
If the size of the data the CM is commanded to collect would exceed the
maximum file-size limit of the data collection mechanism, the CM will
limit the file size accordingly and set the 'MeasStatus' attribute to a
value of 'sampleTruncated'. If this occurs, the file will contain valid
data, from the beginning of the capture, but will represent fewer bins
than configured for the measurement.
